Contributions of the community-based organization program funded by the Centers For Disease Control and Prevention to linkage to HIV medical care
Marano-Lee M , Williams W , Xu S , Andia J , Shapatava E . Public Health Rep 2024 333549241252579 OBJECTIVE: Linkage to HIV medical care is important in the continuum of HIV care and health outcomes for people with HIV. The objective of this analysis was to identify how the community-based organization (CBO) program contributes to linkage to HIV medical care among people with newly diagnosed HIV in the Centers for Disease Control and Prevention's (CDC's) HIV testing program. METHODS: We analyzed HIV linkage-to-care data submitted to CDC from 2019 through 2021. Linkage was defined as confirmation that an individual attended their first HIV medical care appointment within 30 days of their HIV test date. We included in the analysis data submitted from the health department (HD) program that included 61 state and local HDs in the United States, Puerto Rico, and the US Virgin Islands and the CBO program that included 150 CBOs. RESULTS: The CBO program linked a higher proportion of people to HIV medical care within 30 days of diagnosis (86.7%) than the HD program (73.7%). By population group, the proportion linked in the CBO program was higher than the proportion linked in the HD program among men who have sex with men (prevalence ratio [PR] = 1.13; P < .001), men who have sex with men/people who inject drugs (PR = 1.29; P < .001), transgender people (PR = 1.28; P < .001), and those reporting no sexual contact or injection drug use (PR = 1.34; P < .001). In the Cox proportional hazards model, time to linkage in the CBO program was significantly shorter than in the HD program (hazard ratio = 0.63; P < .001). CONCLUSION: This analysis shows that the CBO program fills a vital need in linking newly diagnosed HIV-positive people to HIV medical care, which is important in the HIV care continuum and for viral suppression. |
Asian people reached by the Centers for Disease Control and Prevention HIV testing program in the United States: HIV testing, linkage to HIV medical care, and interview for partner services 2014-2020
Xu S , Wang G , Williams W , Marano Lee M , Wright C , Uhl G . AIDS Educ Prev 2024 36 (2) 103-112 The purpose of this analysis is to describe HIV tests and associated outcomes for Asian people reached by the Centers for Disease Control and Prevention (CDC) HIV testing program. We analyzed CDC-funded HIV tests among Asian individuals in the United States, Puerto Rico, and the U.S. Virgin Islands (2014-2020). Of the 415,560 tests, the positivity of new diagnoses was higher among males (0.49%, aPR = 7.64) than females (0.06%), and in the West (0.42%, aPR = 1.15) than in the South (0.25%). In non-health care settings, positivity was highest among men who have sex with men (MSM; 0.87%) and transgender people (0.46%). Linkage to HIV medical care among Asian people was 87.5%, and 70.7% were interviewed for partner services. Our findings suggest that improvements are crucial, particularly for Asian MSM, in linkage to care and interview for partner services. |
COVID-19 testing of United States-bound agricultural workers in Mexico
Teleaga J , White ZA , Cervantes J , Assael R , Barrera G , Toney S , Marano N , Rodriguez Lainz A , Assael C , Ortega A , Chappelle CG , Bustamante N , Moser K , Posey DL . J Immigr Minor Health 2023 25 (6) 1295-1301 The COVID-19 pandemic presents global health, welfare, and economic concerns. The agricultural workforce has experienced adverse effects, placing the U.S. food supply at risk. Agricultural workers temporarily travel to the United States on H-2A visas to supplement the agricultural workforce. Approximately 300,000 agricultural workers enter the United States with H-2A visas each year; over 90.0% are from Mexico. During February-May 2021, a COVID-19 testing pilot was performed with Clínica Médica Internacional (CMI), a clinic that performs medical examinations for US-bound immigrants, to determine the SARS-CoV-2 infection status of H-2A agricultural workers in Mexico before entry to the US. The CerTest VIASURE Real Time PCR Detection Kit was used. Participants' demographic information, test results, and testing turnaround times were collected. Workers who tested positive for SARS-CoV-2 completed isolation before US entry. During the pilot, 1195 H-2A workers were tested; 15 (1.3%) tested positive. Average reporting time was 31 h after specimen collection. This pilot demonstrated there is interest from H-2A employers and agents in testing the H-2A community before US entry. Testing for SARS-CoV-2 can yield public health benefit, is feasible, and does not delay entry of temporary agricultural workers to the US. |
Diagnostic accuracy of three computer-aided detection systems for detecting pulmonary tuberculosis on chest radiography when used for screening: Analysis of an international, multicenter migrants screening study
Gelaw SM , Kik SV , Ruhwald M , Ongarello S , Egzertegegne TS , Gorbacheva O , Gilpin C , Marano N , Lee S , Phares CR , Medina V , Amatya B , Denkinger CM . PLOS Glob Public Health 2023 3 (7) e0000402 The aim of this study was to independently evaluate the diagnostic accuracy of three artificial intelligence (AI)-based computer aided detection (CAD) systems for detecting pulmonary tuberculosis (TB) on global migrants screening chest x-ray (CXR) cases when compared against both microbiological and radiological reference standards (MRS and RadRS, respectively). Retrospective clinical data and CXR images were collected from the International Organization for Migration (IOM) pre-migration health assessment TB screening global database for US-bound migrants. A total of 2,812 participants were included in the dataset used for analysis against RadRS, of which 1,769 (62.9%) had accompanying microbiological test results and were included against MRS. All CXRs were interpreted by three CAD systems (CAD4TB v6, Lunit INSIGHT v4.9.0, and qXR v2) in offline setting, and re-interpreted by two expert radiologists in a blinded fashion. The performance was evaluated using receiver operating characteristics curve (ROC), estimates of sensitivity and specificity at different CAD thresholds against both microbiological and radiological reference standards (MRS and RadRS, respectively), and was compared with that of the expert radiologists. The area under the curve against MRS was highest for Lunit (0.85; 95% CI 0.83-0.87), followed by qXR (0.75; 95% CI 0.72-0.77) and then CAD4TB (0.71; 95% CI 0.68-0.73). At a set specificity of 70%, Lunit had the highest sensitivity (81.4%; 95% CI 77.9-84.6); at a set sensitivity of 90%, specificity was also highest for Lunit (54.5%; 95% CI 51.7-57.3). The CAD systems performed comparable to the sensitivity (98.3%), and except CAD4TB, to specificity (13.7%) of the expert radiologists. Similar trends were observed when using RadRS. Area under the curve against RadRS was highest for CAD4TB (0.87; 95% CI 0.86-0.89) and Lunit (0.87; 95% CI 0.85-0.88) followed by qXR (0.81; 95% CI 0.80-0.83). At a set specificity of 70%, CAD4TB had highest sensitivity (84.1%; 95% CI 82.3-85.8) followed by Lunit (80.9%; 95% CI 78.9-82.7); and at a set sensitivity of 90%, specificity was also highest for CAD4TB (54.6%; 95% CI 51.3-57.8). In conclusion, the study demonstrated that the three CAD systems had broadly similar diagnostic accuracy with regard to TB screening and comparable accuracy to an expert radiologist against MRS. Compared with different reference standards, Lunit performed better than both qXR and CAD4TB against MRS, and CAD4TB and Lunit better than qXR against RadRS. Moreover, the performance of the CADs can be impacted by characteristics of subgroup of population. The main limitation was that our study relied on retrospective data and MRS was not routinely done in individuals with a low suspicion of TB and a normal CXR. Our findings suggest that CAD systems could be a useful tool for TB screening programs in remote, high TB prevalent places where access to expert radiologists may be limited. However, further large-scale prospective studies are needed to address outstanding questions around the operational performance and technical requirements of the CAD systems. |
The implementation of CDC COVID-19 recommendations for testing, isolation, quarantine and movement at emergency intake sites of unaccompanied children in the United States, April 1-May 31, 2021
Bustamante ND , Sauber-Schatz E , Lee D , Hailu K , Liu Y , Pezzi C , Yonkman J , Gonzalez J , Appelgate A , Marano N , Posey DL , Cetron M , Monterroso E . J Immigr Minor Health 2023 1-6 In March 2021, Emergency Intake Sites (EIS) were created to address capacity shortfalls during a surge of Unaccompanied Children at the Mexico-United States land border. The COVID-19 Zone Plan (ZP) was developed to decrease COVID-19 transmission. COVID-19 cumulative percent (%) positivity was analyzed to evaluate the impact of the ZP, venue type and bed capacity across EIS from April 1-May 31, 2021. Results: Of 11 EIS sites analyzed, 54% implemented the recommended ZP. The overall % positivity was 2.47% (95% CI 2.39-2.55). The % positivity at EIS with the ZP, 1.83% (95% CI 1.71-1.95), was lower than that at EIS without the ZP, 2.83%, ( 95% CI 2.72-2.93), and showed a lower 7-day moving average of % positivity. Conclusion: Results showed a possible effect of the ZP on % positivity when controlling for venue type and bed capacity in a specific EIS group comparison, indicating that all three variables could have had effect on % positivity. They also showed that smaller intake facilities may be recommendable during public health emergencies. |

CDC-Funded HIV testing and linkage to HIV medical care among American Indian and Alaska Native People in the United States, 2014-2020
Moore A , Williams W , Marano-Lee M , Williams N , Xu S , Uhl G . Public Health Rep 2022 333549221121672 OBJECTIVE: An estimated 1 in 5 American Indian and Alaska Native (AI/AN) adults living with HIV are unaware of their status. We investigated HIV testing among AI/AN people receiving a Centers for Disease Control and Prevention (CDC)-funded test from 2014 through 2020. METHODS: We analyzed data on CDC-funded HIV tests reported by health departments and community-based organizations in the United States. We described the number of CDC-funded HIV tests, the percentage of people with newly and previously diagnosed HIV, and linkage to HIV medical care within 90 days of diagnosis. RESULTS: CDC-funded health departments and community-based organizations provided 99 227 HIV tests to AI/AN people during 2014-2020. Seven hundred thirty-five (0.7%) AI/AN people were diagnosed with HIV; 361 (0.4%) were newly diagnosed, 319 (0.3%) had a previous HIV diagnosis, and 55 (0.1%) had a previously unknown HIV status. Positivity for new diagnoses was highest among the following population groups tested in non-health care settings: men who had sex with men (MSM; n = 72, 1.2%), MSM who inject drugs (n = 12, 1.8%), and transgender people (n = 12, 1.5%). The percentage of linkage to HIV medical care was 80.6% for newly diagnosed people and 78.2% for previously diagnosed people. CONCLUSIONS: MSM AI/AN, including those who inject drugs, and transgender AI/AN may benefit from prioritized HIV testing. All AI/AN people with HIV, whether newly or previously diagnosed, should rapidly link to HIV medical care and receive support throughout the continuum of care. Our findings can inform which AI/AN population subgroups may benefit from enhanced HIV testing efforts and interventions. |
Adults aged 50 years reached by the Centers For Disease Control And Prevention's HIV testing programs in the United States and US dependent areas, 2019
Marano-Lee M , Williams W , Huang T , Uhl G . Public Health Rep 2022 333549221120239 OBJECTIVES: Older adults represent nearly half of people living with HIV in the United States. The objective of this analysis was to describe HIV testing, demographic characteristics, and risks of adults aged 50 years (older adults) reached in 2019 by HIV testing programs funded by the Centers for Disease Control and Prevention (CDC). METHODS: We collected data from 101 CDC-funded community-based organizations and 61 health departments. All funding recipients submitted deidentified program service data for 2019 through a secure online CDC-supported system. We used multivariable robust Poisson regression to assess the association between demographic and risk characteristics and the proportion of tests that resulted in a new diagnosis. We also assessed the proportion of people who received a positive test result, were linked to HIV medical care, and were interviewed for partner services. RESULTS: During 2019, among 2 452 507 CDC-funded HIV tests provided in the United States, 412 164 (16.8%) were provided to older adults. Among the 1059 (0.26% positivity) older adults with newly diagnosed HIV infection for whom we had data, 582 (68.4%) were linked to HIV medical care within 30 days of diagnosis and 494 (72.1%) were interviewed for partner services. Among the 2858 older adults with previously diagnosed HIV infection, 1321 (46.2%) reported not being in HIV medical care at the time of the test; of those with linkage data, 425 (49.9%) were linked to HIV medical care within 30 days of testing HIV positive. CONCLUSIONS: More rapid disease progression and higher morbidity and mortality rates among older adults suggest that services are needed to ensure early diagnosis, rapid linkage, and interview for partner services. |
Lessons Learned From a Qualitative COVID-19 Investigation Among Essential Workers With Limited English Proficiency in Southwest Kansas.
Jaramillo J , Moran Bradley B , Jentes ES , Rahman M , Sood NJ , Weiner Ph DJ , Marano N , Ahmed FS , Kumar GS . Health Educ Behav 2022 49 (2) 10901981221080091 In this commentary, we briefly describe our methodology in conducting a remote qualitative investigation with essential workers from southwest Kansas, and then describe some key considerations, challenges, and lessons learned in recruiting and conducting interviews remotely. From August 4, 2020 through August 26, 2020, Centers for Disease Control and Prevention (CDC) staff conducted five phone interviews with culturally and linguistically diverse employees in southwest Kansas to understand COVID-19 knowledge, attitudes, and practices and communication preferences. Our experience details the potential challenges of the federal government in recruiting individuals from these communities and highlights the possibilities for more effectively engaging health department and community partners to support investigation efforts. Optimizing recruitment strategies with additional participation from community partners, developing culturally and linguistically appropriate data collection tools, and providing supportive resources and services may augment participation from refugee, immigrant, and migrant (RIM) communities in similar remote investigations. |
Post-arrival evaluation of immigrant and refugee children in the USA with latent tuberculosis infection diagnosed overseas, 20072019
Wang Z , Posey DL , Brostrom RJ , Morris SB , Marano N , Phares CR . J Pediatr 2022 245 149-157 e1 OBJECTIVE: To assess outcomes from the U.S. post-arrival evaluation of newly arrived immigrant and refugee children aged 2-14 years who were diagnosed with latent tuberculosis infection (LTBI) during a required overseas medical examination. STUDY DESIGN: We compared overseas and U.S. interferon-γ release assay (IGRA)/tuberculin skin test (TST) results and LTBI diagnosis; assessed post-arrival LTBI treatment initiation and completion; and evaluated the impact of switching from TST to IGRA to detect Mycobacterium tuberculosis (Mtb) infection overseas. RESULTS: 73,014 children were diagnosed with LTBI overseas and arrived in the United States during 2007‒2019. In the United States, 45,939 (62.9%) completed, and 1,985 (2.7%) initiated but did not complete a post-arrival evaluation. Among these 47,924 children, 30,360 (63.4%) were retested for Mtb infection. For 17,996 children with a positive overseas TST, 73.8% were negative when retested by IGRA. For 1,051 children with a positive overseas IGRA, 58.0% were negative when retested by IGRA. Overall, among children who completed a post-arrival evaluation, 18,544 (40.4%) were evaluated as having no evidence of TB infection, and 25,919 (56.4%) had their overseas LTBI diagnosis confirmed. Among the latter, 17,229 (66.5%) initiated and 9,185 (35.4%) completed LTBI treatment. CONCLUSIONS: Requiring IGRA testing overseas could more effectively identify children who will benefit from LTBI treatment. However, IGRA reversions may occur, highlighting the need for individualized assessment for risk of infection, progression, and poor outcome when making diagnostic and treatment decisions. Strategies are needed to increase the proportions receiving a post-arrival evaluation and completing LTBI treatment. |
Disease surveillance among U.S.-bound immigrants and refugees - Electronic Disease Notification System, United States, 2014-2019
Phares CR , Liu Y , Wang Z , Posey DL , Lee D , Jentes ES , Weinberg M , Mitchell T , Stauffer W , Self JL , Marano N . MMWR Surveill Summ 2022 71 (2) 1-21 PROBLEM/CONDITION: Each year, approximately 500,000 immigrants and tens of thousands of refugees (range: 12,000-85,000 during 2001-2020) move to the United States. While still abroad, immigrants, refugees, and others who apply for admission to live permanently in the United States must undergo a medical examination. This examination identifies persons with class A or B conditions. Applicants with class A conditions are inadmissible. Infectious conditions that cause an applicant to be inadmissible include infectious tuberculosis (TB) disease (class A TB), infectious syphilis, gonorrhea, and infectious Hansen's disease. Applicants with class B conditions are admissible but might require treatment or follow-up. Class B TB includes persons who completed successful treatment overseas for TB disease (class B0), those with signs or symptoms suggestive of TB but whose overseas laboratory tests and clinical examinations ruled out current infectious TB disease (class B1), those with a diagnosis of latent TB infection (LTBI) (class B2), and the close contacts of persons known to have TB disease (class B3). Voluntary public health interventions might also be offered during the overseas examination. After arriving in the United States, a follow-up TB examination is recommended for persons with class B TB. PERIOD COVERED: This report summarizes health information that was reported to CDC's Electronic Disease Notification (EDN) system for refugees, immigrants, and eligible others who arrived in the United States during 2014-2019. Eligible others are persons who although not classified as refugees (e.g., certain parolees, special immigrant visa holders, and follow-to-join asylees) are eligible for the same services and benefits as refugees. DESCRIPTION OF SYSTEM: The EDN system has both surveillance and programmatic components. The surveillance component is a centralized database that collects 1) health-related data from the overseas medical examination for immigrants with class A or B conditions and for all refugees and eligible others and 2) TB-related data from the postarrival TB examination. The programmatic component is a reporting system that sends arrival notifications to state and local health agencies in the jurisdiction where newly arriving persons have reported intending to live and provides state and local health agencies and other authorized users with medical data from overseas examinations. RESULTS: During 2014-2019, approximately 3.5 million persons moved to the United States from abroad, including 3.2 million immigrants, 313,890 refugees, and 95,993 eligible others. Among these, the overseas examination identified 139,683 persons (3,903 per 100,000 persons examined) with class B TB, 54 with primary or secondary syphilis (30 per 100,000 persons tested), 761 with latent syphilis (415 per 100,000 persons tested), and, after laboratory testing for gonorrhea was added in 2016, a total of 131 with gonorrhea (374 per 100,000 persons tested). Refugees were offered additional, voluntary interventions, including vaccinations and presumptive treatment for parasites. By 2019, first- and second-dose coverage with measles-containing vaccine were 96% and 80%, respectively. In refugee populations for whom presumptive treatment is recommended, up to 96% of refugees, depending on the specific regimen, were offered and accepted treatment. For the 139,683 persons identified overseas with class B TB, EDN sent arrival notifications and overseas medical data to the appropriate state or local health agency to facilitate postarrival TB examinations. Among 101,119 persons identified overseas as having class B0 TB (6,586) or class B1 TB (94,533), a total of 67,432 (67%) had a complete postarrival examination reported to EDN. Among 35,814 children aged 2-14 years identified overseas with class B2 TB, 20,758 (58%) had a complete postarrival examination reported to EDN. (Adults are not routinely tested for immune reactivity to Mycobacterium tuberculosis during the overseas medical examination.) Among those with a complete postarrival examination reported to EDN, the number with a diagnosis of culture-positive TB disease within the first year of arrival was 464 (688 cases per 100,000 persons examined) for those with class B0 or B1 TB and was 11 (53 cases per 100,000 persons examined) for children with class B2 TB. INTERPRETATION: During 2014-2019, the overseas medical examination system prevented importation of 6,586 cases of infectious TB, 815 cases of syphilis, and 131 cases of gonorrhea. When the examination is used to offer public health interventions, most refugees (up to 96%) accept the intervention. Postarrival follow-up examinations, which were completed for 88,190 persons and identified 475 cases of culture-positive TB, represent an important opportunity to further limit spread of TB disease in the United States by identifying and providing, if needed, preventive care for those with LTBI or treatment for those with disease. PUBLIC HEALTH ACTION: Federal, state, and local health departments and agencies should continue to use EDN data to monitor, evaluate, and improve health-related programs and policies aimed at U.S.-bound or recently arrived immigrants, refugees, and eligible others. Additional public health interventions that could be offered during the overseas medical examination should be considered (e.g., treatment for LTBI). Finally, for persons with class B TB, measures should be taken to identify and remove barriers to completing postarrival examinations to reduce risk for TB disease and community transmission, along with measures to encourage reporting of completed examinations for better data-driven decision-making. |
Multidrug-resistant tuberculosis in U.S.-bound immigrants and refugees
Liu Y , Posey DL , Yang Q , Weinberg MS , Maloney SA , Lambert LA , Ortega LS , Marano N , Cetron MS , Phares CR . Ann Am Thorac Soc 2021 19 (6) 943-951 RATIONALE: Approximately two-thirds of new cases of tuberculosis (TB) in the United States are among non-U.S.-born persons. Culture-based overseas TB screening in U.S.-bound immigrants and refugees has substantially reduced the importation of TB into the United States, but it is unclear to what extent this program prevents the importation of multidrug-resistant TB (MDR-TB). OBJECTIVES: To study the epidemiology of MDR-TB in U.S.-bound immigrants and refugees, and to evaluate effect of culture-based overseas TB screening in U.S.-bound immigrants and refugees on reducing the importation of MDR-TB into the United States. METHODS: We analyzed data of immigrants and refugees who completed overseas treatment for culture-positive TB during 2015-2019. We also compared mean annual number of MDR-TB cases in non-U.S.-born persons within 1 year of arrival in the United States between 1996-2006 (when overseas screening followed a smear-based algorithm) and 2014-2019 (after full implementation of a culture-based algorithm). RESULTS: Of 3,300 culture-positive TB cases prevented by culture-based overseas TB screening in immigrants and refugees during 2015-2019, 122 (3.7%, 95% confidence interval (CI) 3.1-4.1) had MDR-TB, 20 (0.6%, 95% CI 0.3-0.9) had rifampicin-resistant TB, 382 (11.6%, 95% CI 10.5-12.7) had isoniazid-resistant TB, and 2,776 (84.1%, 95% CI 82.9-85.4) had rifampicin- and isoniazid-susceptible TB. None were diagnosed with extensively drug-resistant TB (XDR-TB). Culture-based overseas TB screening in U.S.-bound immigrants and refugees prevented 24.4 MDR-TB cases per year from arriving in the United States, 18.2 cases more than smear-based overseas TB screening. Mean annual number of MDR-TB cases among non-U.S.-born persons within 1 year of arrival in the United States decreased from 34.6 cases in 1996-2006 to 19.5 cases in 2014-2019 (difference of 15.1, p<0.001). CONCLUSIONS: Culture-based overseas TB screening in U.S.-bound immigrants and refugees substantially reduced the importation of MDR-TB into the United States. |
Contributions of community-based organizations funded by the Centers for Disease Control and Prevention's HIV Testing Program
Marano-Lee M , Williams W , Uhl G , Eke A , Joshua T , Xu S , Carter J , Rakestraw A , Dunbar E . J Public Health Manag Pract 2021 28 (2) E461-E466 CONTEXT: HIV testing is a critically important first step in preventing and reducing HIV transmission. Community-based organizations (CBOs) are uniquely positioned to provide HIV testing and other prevention services to populations disproportionately affected by HIV infection. OBJECTIVE: The purpose of this analysis was to assess CDC-funded health department (HD) and CBO testing programs during 2012-2017, including the number of tests and HIV positivity. DESIGN: This is an analysis of National HIV Prevention Program Monitoring and Evaluation HIV testing data submitted between 2012 and 2017 to CDC. SETTING: Sixty-one CDC-funded state and local HDs in the United States, Puerto Rico, and the US Virgin Islands and between 122 and 175 CDC-funded CBOs, depending on the year. PARTICIPANTS: Persons who received HIV testing at CDC-funded CBOs and HDs. MAIN OUTCOME MEASURE: The number of HIV tests and positivity at CBOs were compared with HDs overall and to HDs in non-health care settings that, like CBOs, include HIV risk data and are in similar locations. RESULTS: CBOs accounted for 7625 (8%) new diagnoses but conducted only 3% of the almost 19 million CDC-funded HIV tests from 2012 to 2017. Newly diagnosed HIV positivity at CBOs (1.4%) was nearly 3 times the new positivity at HDs overall (0.5%) and twice that of new positivity at HDs in non-health care settings (0.7%). A higher proportion of tests at CBOs were conducted among groups at risk, and new HIV positivity was higher for most demographic and population groups than new HIV positivity at HDs in non-health care settings. CONCLUSION: These findings demonstrate the essential role CDC-funded CBOs have in reaching, testing, and diagnosing groups at high risk for acquiring HIV infection. |
Tuberculosis among newly arrived immigrants and refugees in the United States

Ann Am Thorac Soc 2020 17 (11) 1401-1412 Rationale: U.S. health departments routinely conduct post-arrival evaluation of immigrants and refugees at risk for tuberculosis (TB), but this important intervention has not been thoroughly studied.Objectives: To assess outcomes of the post-arrival evaluation intervention.Methods: We categorized at-risk immigrants and refugees as having had recent completion of treatment for pulmonary TB disease overseas (including in Mexico and Canada); as having suspected TB disease (chest radiograph/clinical symptoms suggestive of TB) but negative culture results overseas; or as having latent TB infection (LTBI) diagnosed overseas. Among 2.1 million U.S.-bound immigrants and refugees screened for TB overseas during 2013-2016, 90,737 were identified as at risk for TB. We analyzed a national data set of these at-risk immigrants and refugees and calculated rates of TB disease for those who completed post-arrival evaluation.Results: Among 4,225 persons with recent completion of treatment for pulmonary TB disease overseas, 3,005 (71.1%) completed post-arrival evaluation within 1 year of arrival; of these, TB disease was diagnosed in 22 (732 cases/100,000 persons), including 4 sputum culture-positive cases (133 cases/100,000 persons), 13 sputum culture-negative cases (433 cases/100,000 persons), and 5 cases with no reported sputum-culture results (166 cases/100,000 persons). Among 55,938 with suspected TB disease but negative culture results overseas, 37,089 (66.3%) completed post-arrival evaluation; of these, TB disease was diagnosed in 597 (1,610 cases/100,000 persons), including 262 sputum culture-positive cases (706 cases/100,000 persons), 281 sputum culture-negative cases (758 cases/100,000 persons), and 54 cases with no reported sputum-culture results (146 cases/100,000 persons). Among 30,574 with LTBI diagnosed overseas, 18,466 (60.4%) completed post-arrival evaluation; of these, TB disease was diagnosed in 48 (260 cases/100,000 persons), including 11 sputum culture-positive cases (60 cases/100,000 persons), 22 sputum culture-negative cases (119 cases/100,000 persons), and 15 cases with no reported sputum-culture results (81 cases/100,000 persons). Of 21,714 persons for whom treatment for LTBI was recommended at post-arrival evaluation, 14,977 (69.0%) initiated treatment and 8,695 (40.0%) completed treatment.Conclusions: Post-arrival evaluation of at-risk immigrants and refugees can be highly effective. To optimize the yield and impact of this intervention, strategies are needed to improve completion rates of post-arrival evaluation and treatment for LTBI. |
Infectious disease outbreaks among forcibly displaced persons: an analysis of ProMED reports 1996-2016
Desai AN , Ramatowski JW , Marano N , Madoff LC , Lassmann B . Confl Health 2020 14 49 BACKGROUND: The United Nations Refugee Agency (UNHCR) estimates the number of forcibly displaced people increased from 22.7 million people in 1996 to 67.7 million people in 2016. Human mobility is associated with the introduction of infectious disease pathogens. The aim of this study was to describe the range of pathogens in forcibly displaced populations over time using an informal event monitoring system. METHODS: We conducted a retrospective analysis of ProMED, a digital disease monitoring system, to identify reports of outbreak events involving forcibly displaced populations between 1996 and 2016. Number of outbreak events per year was tabulated. Each record was assessed to determine outbreak location, pathogen, origin of persons implicated in the outbreak, and suspected versus confirmed case counts. RESULTS: One hundred twenty-eight independent outbreak events involving forcibly displaced populations were identified. Over 840,000 confirmed or suspected cases of infectious diseases such as measles, cholera, cutaneous leishmaniasis, dengue, and others were reported in 48 destination countries/territories. The average rate of outbreak events concerning forcibly displaced persons per total number of reports published on ProMED per year increased over time. The majority of outbreak events (63%) were due to acquisition of disease in the destination country. CONCLUSION: This study found that reports of outbreak events involving forcibly displaced populations have increased in ProMED. The events and outbreaks detected in this retrospective review underscore the importance of capturing displaced populations in surveillance systems for rapid detection and response. |
CDC's Community-Based Organization Behavioral Outcomes Project: Perspectives for researchers, implementers and funders
Williams WO , Uhl G , Eke A , Fisher H , Joshua T , Heitgerd J , Marano M , Moore A , Sapiano T , Shelley G , Stein R . AIDS Behav 2020 25 (1) 284-293 Behavioral interventions have been a crucial tool for the prevention of HIV transmission since early in the epidemic. The Centers for Disease Control and Prevention (CDC) has provided funding for evidence-based behavioral interventions (EBIs) at health departments and community-based organizations (CBOs) since 2004. From 2006 to 2015, CDC funded 25 CBOs to evaluate one or more of seven EBIs designed to prevent HIV through the Community-based Organization Behavioral Outcomes Project (CBOP) as implemented outside of a research setting. For each EBI, CBOP showed that most HIV risk behaviors improved after the intervention, and improvements were similar to those observed in research studies. Our findings show that behavioral interventions can be successfully implemented in real-world settings. Although the focus of HIV prevention has largely shifted toward biomedical interventions in recent years, successful implementation often depends on behavioral components. Lessons from CBOP can inform future efforts to develop and implement behavioral interventions for HIV and other areas of public health. |
Research ethics and refugee health: a review of reported considerations and applications in published refugee health literature, 2015-2018
Seagle EE , Dam AJ , Shah PP , Webster JL , Barrett DH , Ortmann LW , Cohen NJ , Marano NN . Confl Health 2020 14 39 Introduction: Public health investigations, including research, in refugee populations are necessary to inform evidence-based interventions and care. The unique challenges refugees face (displacement, limited political protections, economic hardship) can make them especially vulnerable to harm, burden, or undue influence. Acute survival needs, fear of stigma or persecution, and history of trauma may present challenges to ensuring meaningful informed consent and establishing trust. We examined the recently published literature to understand the application of ethics principles in investigations involving refugees. Methods: We conducted a preliminary review of refugee health literature (research and non-research data collections) published from 2015 through 2018 available in PubMed. Article inclusion criteria were: participants were refugees, topic was health-related, and methods used primary data collection. Information regarding type of investigation, methods, and reported ethics considerations was abstracted. Results: We examined 288 articles. Results indicated 33% of investigations were conducted before resettlement, during the displacement period (68% of these were in refugee camps). Common topics included mental health (48%) and healthcare access (8%). The majority (87%) of investigations obtained consent. Incentives were provided less frequently (23%). Most authors discussed the ways in which community stakeholders were engaged (91%), yet few noted whether refugee representatives had an opportunity to review investigational protocols (8%). Cultural considerations were generally limited to gender and religious norms, and 13% mentioned providing some form of post-investigation support. Conclusions: Our analysis is a preliminary assessment of the application of ethics principles reported within the recently published refugee health literature. From this analysis, we have proposed a list of best practices, which include stakeholder engagement, respect for cultural norms, and post-study support. Investigations conducted among refugees require additional diligence to ensure respect for and welfare of the participants. Development of a refugee-specific ethics framework with ethics and refugee health experts that addresses the need for stakeholder involvement, appropriate incentive use, protocol review, and considerations of cultural practices may help guide future investigations in this population. |
Clinical sequelae associated with unresolved tropical splenomegaly in a cohort of recently resettled Congolese refugees in the United States - multiple states, 2015-2018

Am J Trop Med Hyg 2020 103 (1) 485-493 Tropical splenomegaly is often associated with malaria and schistosomiasis. In 2014 and 2015, 145 Congolese refugees in western Uganda diagnosed with splenomegaly during predeparture medical examinations underwent enhanced screening for various etiologies. After anecdotal reports of unresolved splenomegaly and complications after U.S. arrival, patients were reassessed to describe long-term clinical progression after arrival in the United States. Post-arrival medical information was obtained through medical chart abstraction in collaboration with state health partners in nine participating states. We evaluated observed splenomegaly duration and associated clinical sequelae between 130 case patients from eastern Congo and 102 controls through adjusted hierarchical Poisson models, accounting for familial clustering. Of the 130 case patients, 95 (73.1%) had detectable splenomegaly after arrival. Of the 85 patients with records beyond 6 months, 45 (52.9%) had persistent splenomegaly, with a median persistence of 14.7 months (range 6.0-27.9 months). Of the 112 patients with available results, 65 (58.0%) patients had evidence of malaria infection, and the mean splenomegaly duration did not differ by Plasmodium species. Refugees with splenomegaly on arrival were 43% more likely to have anemia (adjusted relative risk [aRR]: 1.43, 95% CI: 1.04-1.97). Those with persistent splenomegaly were 60% more likely (adjusted relative risk [aRR]: 1.60, 95% CI: 1.15-2.23) to have a hematologic abnormality, particularly thrombocytopenia (aRR: 5.53, 95% CI: 1.73-17.62), and elevated alkaline phosphatase (aRR: 1.57, 95% CI: 1.03-2.40). Many patients experienced persistent splenomegaly, contradicting literature describing resolution after treatment and removal from an endemic setting. Other possible etiologies should be investigated and effective treatment, beyond treatment for malaria and schistosomiasis, explored. |
Factors associated with HIV antiretroviral therapy among men who have sex with men in 20 US cities, 2014
Stein R , Xu S , Williams W , Marano M , Eke A , Finlayson T , Paz-Bailey G , Wejnert C . J Urban Health 2019 96 (6) 868-877 Reducing HIV among men who have sex with men (MSM) is a national goal, and early diagnosis, timely linkage to HIV medical care, and ongoing care and treatment are critical for improving health outcomes for MSM with HIV and preventing transmission to others. We assessed demographic, social, and economic factors associated with HIV antiretroviral treatment among HIV-infected MSM. Data are from the National HIV Behavioral Surveillance (NHBS) collected in 2014 among MSM. We estimated prevalence ratios and 95% confidence intervals using average marginal predictions from logistic regression. Overall, 89% of HIV-positive MSM reported currently taking antiretroviral therapy (ART). After controlling for other variables, we found that higher perceived community stigma and not having health insurance were significant risk factors for not taking ART. We also found that high socioeconomic status (SES) was associated with taking ART. Race/ethnicity was not significantly associated with taking ART in either the unadjusted or adjusted analyses. Findings suggest that to increase ART use for MSM with HIV, we need to move beyond individual-level approaches and move towards the development, dissemination, and evaluation of structural and policy interventions that respond to these important social and economic factors. |
Efficacy of a solar concentrator to Inactivate E. coli and C. perfringens spores in latrine waste in Kenya
Murphy JL , Ayers T , Foote A , Woods E , Wamola N , Fagerli K , Waiboci L , Mugoh R , Mintz ED , Zhao K , Marano N , O'Reilly CE , Hill VR . Sci Total Environ 2019 691 401-406 Alternative sanitation options are needed for effective waste management in low-income countries where centralized, large-scale waste treatment is not easily achievable. A newly designed solar concentrator technology utilizes solar thermal energy to treat feces contained in drums. This pilot study assessed the efficacy of the new design to inactivate microbes in 13 treatment drums under field conditions in Kenya. Three-quarters of the drums contained <1000E. coli/g of total solids following 6h of solar thermal treatment and inactivation of thermotolerant C. perfringens spores ranged from <1.8 to >5.0log10. Nearly all (94%) samples collected from treatment drums achieved thermophilic temperatures (>50 degrees C) during the treatment period, however this alone did not ensure samples met the WHO E. coli guideline; higher, sustained thermophilic temperatures tended to be more effective in reaching this guideline. The newly designed solar concentrator was capable of inactivating thermotolerant, environmentally-stable microorganisms as, or possibly more, efficiently than a previous design. Additional data are needed to better characterize how temperature, time, and other parameters affect the ability of the solar concentrator to inactivate microbes in feces. |
Expanding travel medicine in the 21st century to address the health needs of the world's migrants
Marano N , Angelo K , Merrill RD , Cetron MS . J Travel Med 2018 25 (1) The body of knowledge needed to effectively practice travel medicine has expanded since the 1990s, as migrants begin to comprise an increasing proportion of the world's population. We describe the unique needs of migrants, and provide resources available to migration health practitioners. As the number of the world's migrants grows, collaboration across disciplines is key to achieving high-quality migration health practices. |
HIV testing, linkage to HIV medical care, and interviews for partner services among black men who have sex with men - non-health care facilities, 20 southern U.S. jurisdictions, 2016
Marano M , Stein R , Song W , Patel D , Taylor-Aidoo N , Xu S , Scales L . MMWR Morb Mortal Wkly Rep 2018 67 (28) 778-781 Identifying HIV-infected persons who are unaware of their human immunodeficiency virus (HIV) infection status, linking them to care, and reducing health disparities are important national HIV prevention goals (1). Gay, bisexual, and other men who have sex with men (collectively referred to as MSM) accounted for 70% of HIV infection diagnoses in the United States in 2016, despite representing only 2% of the population (2,3). African American or black (black) MSM accounted for 38% of all new diagnoses of HIV infection among MSM (2). Nearly two thirds (63%) of all U.S. black MSM with diagnosed HIV infection reside in the southern United States (2), making targeted HIV prevention activities for black MSM in this region critical. Analysis of CDC-funded HIV testing data for black MSM submitted by 20 health departments in the southern United States in 2016 revealed that although black MSM received 6% of the HIV tests provided, they accounted for 36% of the new diagnoses in non-health care facilities. Among those who received new diagnoses, 67% were linked to HIV medical care within 90 days of diagnosis, which is below the 2020 national goal of linking at least 85% of persons with newly diagnosed HIV infection to care within 30 days (1). Black MSM in the southern United States are the group most affected by HIV, but only a small percentage of CDC tests in the southern United States are provided to this group. Increasing awareness of HIV status through HIV testing, especially among black MSM in the southern United States, is essential for reducing the risk for transmission and addressing disparities. HIV testing programs in the southern United States can reach more black MSM by conducting targeted risk-based testing in non-health care settings and by routine screening in agencies that also provide health care services to black MSM. |

Sci Transl Med 2018 10 (438) Serosurveys are useful for assessing population susceptibility to vaccine-preventable disease outbreaks. Although at-risk populations in remote areas could benefit from this type of information, they face several logistical barriers to implementation, such as lack of access to centralized laboratories, cold storage, and transport of samples. We describe a potential solution: a compact and portable, field-deployable, point-of-care system relying on digital microfluidics that can rapidly test a small volume of capillary blood for disease-specific antibodies. This system uses inexpensive, inkjet-printed digital microfluidic cartridges together with an integrated instrument to perform enzyme-linked immunosorbent assays (ELISAs). We performed a field validation of the system's analytical performance at Kakuma refugee camp, a remote setting in northwestern Kenya, where we tested children aged 9 to 59 months and caregivers for measles and rubella immunoglobulin G (IgG). The IgG assays were determined to have sensitivities of 86% [95% confidence interval (CI), 79 to 91% (measles)] and 81% [95% CI, 73 to 88% (rubella)] and specificities of 80% [95% CI, 49 to 94% (measles)] and 91% [95% CI, 76 to 97% (rubella)] (measles, n = 140; rubella, n = 135) compared with reference tests (measles IgG and rubella IgG ELISAs from Siemens Enzygnost) conducted in a centralized laboratory. These results demonstrate a potential role for this point-of-care system in global serological surveillance, particularly in remote areas with limited access to centralized laboratories. |
Trends in chronic diseases reported by refugees originating from Burma resettling to the United States from camps versus urban areas during 2009-2016
Bardenheier BH , Phares CR , Simpson D , Gregg E , Cho P , Benoit S , Marano N . J Immigr Minor Health 2018 21 (2) 246-256 We examined changes in the prevalence of chronic health conditions among US-bound refugees originating from Burma resettling over 8 years by the type of living arrangement before resettlement, either in camps (Thailand) or in urban areas (Malaysia). Using data from the required overseas medical exam for 73,251 adult (>/= 18 years) refugees originating from Burma resettling to the United States during 2009-2016, we assessed average annual percent change (AAPC) in proportion >/= 45 years and age- and sex-standardized prevalence of obesity, diabetes, hypertension, chronic obstructive pulmonary disease (COPD), and musculoskeletal disease, by camps versus urban areas. Compared with refugees resettling from camps, those coming from urban settings had higher prevalence of obesity (mean 18.0 vs. 5.9%), diabetes (mean 6.5 vs. 0.8%), and hypertension (mean 12.7 vs. 8.1%). Compared with those resettling from camps, those from urban areas saw greater increases in the proportion with COPD (AAPC: 109.4 vs. 9.9) and musculoskeletal disease (AAPC: 34.6 vs. 1.6). Chronic conditions and their related risk factors increased among refugees originating from Burma resettling to the United States whether they had lived in camps or in urban areas, though the prevalence of such conditions was higher among refugees who had lived in urban settings. |

HIV testing, linkage to HIV medical care, and interviews for partner services among women - 61 health department jurisdictions, United States, Puerto Rico, and the U.S. Virgin Islands, 2015
Stein R , Xu S , Marano M , Williams W , Cheng Q , Eke A , Moore A , Wang G . MMWR Morb Mortal Wkly Rep 2017 66 (41) 1100-1104 Diagnoses of human immunodeficiency virus (HIV) infection among women declined 17% during 2011-2015, and a total of 7,498 women received a diagnosis of HIV infection in 2015 (1). Although black or African American (black) women accounted for only 12% of the U.S. female population, 60% of women with newly diagnosed HIV infection were black (1,2). By the end of 2014, an estimated 255,900 women were living with HIV infection (3), including approximately 12% who did not know they were infected; in addition, approximately 45% of women who had received a diagnosis had not achieved viral suppression (3). HIV testing is an important public health strategy for identifying women with HIV infection and linking them to HIV medical care. Analysis of CDC-funded program data submitted by 61 health departments in 2015 indicated that among 4,749 women tested who received a diagnosis of HIV infection, 2,951 (62%) had received a diagnosis in the past (previous diagnosis), and 1,798 (38%) were receiving a diagnosis for the first time (new diagnosis). Of those who had received a previous diagnosis, 87% were not in HIV medical care at the time of the current test. Testing and identifying women who are living with HIV infection but who are not in care (regardless of when they received their first diagnosis) and rapidly linking them to care so they can receive antiretroviral therapy and become virally suppressed are essential for reducing HIV infection among all women. |
Sanitation practices and perceptions in Kakuma refugee camp, Kenya: Comparing the status quo with a novel service-based approach
Nyoka R , Foote AD , Woods E , Lokey H , O'Reilly CE , Magumba F , Okello P , Mintz ED , Marano N , Morris JF . PLoS One 2017 12 (7) e0180864 Globally, an estimated 2.5 billion people lack access to improved sanitation. Unimproved sanitation increases the risk of morbidity and mortality, especially in protracted refugee situations where sanitation is based on pit latrine use. Once the pit is full, waste remains in the pit, necessitating the construction of a new latrine, straining available land and funding resources. A viable, sustainable solution is needed. This study used qualitative and quantitative methods to design, implement, and pilot a novel sanitation system in Kakuma refugee camp, Kenya. An initial round of 12 pre-implementation focus group discussions (FGDs) were conducted with Dinka and Somali residents to understand sanitation practices, perceptions, and needs. FGDs and a supplementary pre-implementation survey informed the development of an innovative sanitation management system that incorporated the provision of urine and liquid-diverting toilets, which separate urine and fecal waste, and a service-based sanitation system that included weekly waste collection. The new system was implemented on a pilot scale for 6 weeks. During the implementation, bi-weekly surveys were administered in each study household to monitor user perceptions and challenges. At the end of the pilot, the sanitation system was assessed using a second round of four post-implementation FGDs. Those who piloted the new sanitation system reported high levels of user satisfaction. Reported benefits included odor reduction, insect/pest reduction, the sitting design, the appropriateness for special populations, and waste collection. However, urine and liquid diversion presented a challenge for users who perform anal washing and for women who had experienced female genital mutilation. Refugee populations are often culturally and ethnically diverse. Using residents' input to inform the development of sanitation solutions can increase user acceptability and provide opportunities to improve sanitation system designs based on specific needs. |
HIV testing in nonhealthcare facilities among adolescent MSM
Marano MR , Stein R , Williams WO , Wang G , Xu S , Uhl G , Cheng Q , Rasberry CN . AIDS 2017 31 Suppl 3 S261-s265 OBJECTIVES: To describe the extent to which Centers for Disease Control and Prevention (CDC)-funded HIV testing in nonhealthcare facilities reaches adolescent MSM, identifies new HIV infections, and links those newly diagnosed to medical care. METHODS/DESIGN: We describe HIV testing, newly diagnosed positivity, and linkage to medical care for adolescent MSM who received a CDC-funded HIV test in a nonhealthcare facility in 2015. We assess outcomes by race/ethnicity, HIV-related risk behaviors, and US geographical region. RESULTS: Of the 703 890 CDC-funded HIV testing events conducted in nonhealthcare facilities in 2015, 6848 (0.9%) were provided to adolescent MSM aged 13-19 years. Among those tested, 1.8% were newly diagnosed with HIV, compared with 0.7% among total tests provided in nonhealthcare facilities regardless of age and sex. The odds of testing positive among black adolescent MSM were nearly four times that of white adolescent MSM in multivariable analysis (odds ratio = 3.97, P < 0.001). Among adolescent MSM newly diagnosed with HIV, 67% were linked to HIV medical care. Linkage was lower among black (59%) and Hispanic/Latino adolescent MSM (71%) compared with white adolescent MSM (88%). CONCLUSION: CDC-funded nonhealthcare facilities can reach and provide HIV tests to adolescent MSM and identify new HIV infections; however, given the low rate of HIV testing overall and high engagement in HIV-related risk behaviors, there are opportunities to increase access to HIV testing and linkage to care for HIV-positive adolescent MSM. Efforts are needed to identify and address the barriers that prevent black and Hispanic/Latino adolescent MSM from being linked to HIV medical care in a timely manner. |
HIV testing, linkage to HIV medical care, and interviews for partner services among youths - 61 health department jurisdictions, United States, Puerto Rico, and the U.S. Virgin Islands, 2015
Stein R , Song W , Marano M , Patel H , Rao S , Morris E . MMWR Morb Mortal Wkly Rep 2017 66 (24) 629-635 Identifying persons living with human immunodeficiency virus (HIV) who are unaware of their infection, linking them to HIV medical care, and reducing health disparities are important national goals (1). Of the 8,841 teens and young adults aged 13-24 years (collectively referred to as youths in this report) who received a diagnosis of HIV in 2014, 70% were young men who have sex with men (MSM) (2). In the same year, an estimated 52% of young MSM living with HIV were unaware of their infection compared with 15% among all persons living with HIV (3). An average of 22% of high school students who have had sexual intercourse and 33% of young adults (persons aged 18-24 years) reported ever receiving an HIV test (4). CDC recommends screening all persons aged 13-64 years, with annual rescreening for persons at high risk for HIV infection (5). Analysis of CDC-funded program data for youths submitted by 61 health departments in 2015 revealed that young MSM, who accounted for 83% of new diagnoses among all youths in non-health care facilities, received 28% of HIV tests.* The 2020 national goal is to link at least 85% of HIV-positive persons to HIV medical care within 30 days of diagnosis. In this analysis, 66% of youths who received positive test results for HIV infection were linked to care within 90 days of diagnosis. Increasing the number of youths at risk for HIV infection who are tested for HIV on a regular basis and ensuring that youths who receive positive test results for HIV are rapidly linked to and retained in appropriate medical care, including early initiation of antiretroviral therapy, are essential steps for reducing HIV infection in this vulnerable population. |
Evaluation of the field performance of ImmunoCard STAT! rapid diagnostic test for rotavirus in Dadaab refugee camp and at the Kenya-Somalia Border

Am J Trop Med Hyg 2017 96 (6) 1302-1306 Rotavirus commonly causes diarrhea in children, leading to hospitalization and even death. Rapid diagnostic tests are feasible alternatives for determining rotavirus outbreaks in refugee camps that have inadequate laboratory capacity.We evaluated the field performance of ImmunoCard STAT! Rotavirus (ICS-RV) in Dadaab Refugee Camp and at the Kenya-Somalia border. From May to December 2014, we prospectively enrolled children aged < 5 years hospitalized with acute diarrhea, defined as >= 3 episodes of loose stool in 24 hours for < 7 days. Stool samples were collected and tested by trained surveillance clerks using ICS-RV per manufacturer's instructions. The field performance characteristics of ICS-RV were evaluated against the gold standard test, PremierTM Rotaclone enzyme immunoassay. The operational characteristics were evaluated usingWorld Health Organization (WHO) ASSURED criteria to determine whether ICS-RV is appropriate as a point-of-care test by administering a standard questionnaire and observing surveillance clerks performing the test. We enrolled 213 patients with a median age of 10 months (range = 1-48); 58.2%weremale. A total of 71 (33.3%) and 60 (28.2%) patients tested positive for rotavirus infection by immunoassay and ICS-RV, respectively. The sensitivity, specificity, and positive and negative predictive values of ICS-RV compared with the immunoassay were 83.1% (95% confidence interval [CI] = 72.3-91.0), 99.3% (95% CI = 96.1-100), 98.3% (95% CI = 91.1-100), and 92.1% (95% CI = 86.6-95.5), respectively. The ICS-RV fulfilled theWHO ASSURED criteria for point-of-care testing. ICS-RV is a field-ready point-of-care test with good field performance and operational characteristics. It can be useful in determining rotavirus outbreaks in resource-limited settings. |
