Acanthamoeba infection and nasal rinsing, United States, 1994-2022
Haston JC , Serra C , Imada E , Martin E , Ali IKM , Cope JR . Emerg Infect Dis 2024 30 (4) 783-785 We describe 10 patients with nonkeratitis Acanthamoeba infection who reported performing nasal rinsing before becoming ill. All were immunocompromised, 7 had chronic sinusitis, and many used tap water for nasal rinsing. Immunocompromised persons should be educated about safe nasal rinsing to prevent free-living ameba infections. |
Estimates of incidence and predictors of fatiguing illness after SARS-CoV-2 infection
Vu QM , Fitzpatrick AL , Cope JR , Bertolli J , Sotoodehnia N , West TE , Gentile N , Unger ER . Emerg Infect Dis 2024 30 (3) 539-547 This study aimed to estimate the incidence rates of post-COVID-19 fatigue and chronic fatigue and to quantify the additional incident fatigue caused by COVID-19. We analyzed electronic health records data of 4,589 patients with confirmed COVID-19 during February 2020-February 2021 who were followed for a median of 11.4 (interquartile range 7.8-15.5) months and compared them to data from 9,022 propensity score-matched non-COVID-19 controls. Among COVID-19 patients (15% hospitalized for acute COVID-19), the incidence rate of fatigue was 10.2/100 person-years and the rate of chronic fatigue was 1.8/100 person-years. Compared with non-COVID-19 controls, the hazard ratios were 1.68 (95% CI 1.48-1.92) for fatigue and 4.32 (95% CI 2.90-6.43) for chronic fatigue. The observed association between COVID-19 and the significant increase in the incidence of fatigue and chronic fatigue reinforces the need for public health actions to prevent SARS-CoV-2 infections. |
Differences in report of post-covid conditions among adults tested for SARS-cov-2 by race and ethnicity: 2022 Porter Novelli SummerStyles Survey, U.S
Feldstein LR , Edwards D , Cope JR , Hagen MB , Saydah S . AJPM Focus 2024 3 (2) 100181 INTRODUCTION: Since March 2020, Hispanic and Black/African American persons have made up a disproportionate number of COVID-19 cases, hospitalizations, and deaths. However, little is known about whether the prevalence of postacute sequelae or post-COVID conditions differs by race/ethnicity. METHODS: This study used cross-sectional survey data collected by Porter Novelli Public Services to determine the prevalence of ≥1 ongoing symptom lasting ≥4 weeks by SARS-CoV-2 test status and racial/ethnic groups among 2,890 adults in the U.S. RESULTS: Overall, 57% (95% CI=54%, 60%) of respondents with positive SARS-CoV-2 tests reported ≥1 ongoing symptom, compared with 22% (95% CI=20%, 24%) of respondents who tested negative. Among those with positive SARS-CoV-2 tests, Hispanic respondents had higher AORs of experiencing ≥1 ongoing symptom (AOR=1.79, 95% CI=1.27, 2.53) than non-Hispanic White respondents. In addition, Hispanic respondents had significantly higher ORs of experiencing 2 or more ongoing symptoms (AOR=2.03, 95% CI=1.45, 2.86), respiratory/cardiac symptoms (AOR=1.47, 95% CI=1.03, 2.07), neurologic symptoms (AOR=1.77, 95% CI=1.26, 2.48), and other symptoms (AOR=1.53, 95% CI=1.09, 2.14) than non-Hispanic White respondents. Non-Hispanic other respondents who reported at least 1 positive SARS-CoV-2 test had significantly higher ORs of experiencing gastrointestinal symptoms (AOR=4.06, 95% CI=1.78, 8.89) than non-Hispanic White respondents. CONCLUSIONS: These results highlight potential disparities in ongoing symptoms, even after accounting for demographic differences, and reinforce the need for culturally appropriate and targeted strategies to increase access to health care and reduce SARS-CoV-2 infections. |
Measuring Success: Disease Intervention Specialists Performance Metrics and Outcome Assessments
Cope AB , Mobley VL , Samoff E . Sex Transm Dis 2023 50 S18-s22 Disease intervention specialists (DIS) are the cornerstone of public health. However, the incremental gains of DIS-led interventions are difficult to detect at the population level. Health departments attempt to quantify the impact of key DIS activities through performance measures that assess how many and how quickly both patients are interviewed, and contacts are notified, tested, and treated. However, DIS work encompasses more than case finding and existing performance measures may not capture the full value DIS provide to health departments. In this article, we first describe how DIS investigations and contact tracing are conducted for sexually transmitted diseases and other communicable diseases to understand how the definition of effectiveness may vary by disease. Then, we examine the benefits and limitations of traditional performance measures using syphilis investigations as an example. Recognizing the limits of existing measures will improve our understanding of DIS impact and assist in the development of new measures of effectiveness that better represent the totality of DIS work. |
Ten Years of Disseminated Gonococcal Infections in North Carolina: A Review of Cases From a Large Tertiary Care Hospital
Sciaudone M , Cope A , Mobley V , Samoff E , Seña AC . Sex Transm Dis 2023 50 (7) 410-414 BACKGROUND: The detection and reporting of disseminated gonococcal infection (DGI) has been increasing across the United States. METHODS: We conducted a retrospective chart review of DGI case-patients diagnosed between 2010 and 2019 at a large tertiary care hospital in North Carolina. RESULTS: We identified 12 DGI case-patients (7 men and 5 women, aged 20 to 44 years), of whom 5 had Neisseria gonorrheae isolated from a sterile site (confirmed), 2 had N. gonorrheae detected at a nonsterile mucosal site and had clinical manifestations consistent with DGI (probable), and 5 did not have N. gonorrheae isolated from any site, but DGI was the most likely diagnosis (suspect). Among the 12 DGI case-patients, the most common manifestation was arthritis or tenosynovitis (n = 11); 1 patient had endocarditis. Half of the patients had significant underlying comorbidities or predisposing factors, including complement deficiency. Eleven of the 12 case-patients were hospitalized, and 4 required surgical intervention. CONCLUSIONS: This case series highlights the difficulty of making a definitive diagnosis of DGI, which could negatively affect reporting to public health authorities and hinder surveillance efforts to determine the true prevalence of DGI. A high index of suspicion is required, and a full diagnostic workup should be pursued in all cases of suspected DGI. |
Possible exposures among mpox patients without reported male-to-male sexual contact - six U.S. Jurisdictions, November 1-December 14, 2022
Sharpe JD , Charniga K , Byrd KM , Stefanos R , Lewis L , Watson J , Feldpausch A , Pavlick J , Hand J , Sokol T , Ortega E , Pathela P , Hennessy RR , Dulcey M , McHugh L , Pietrowski M , Perella D , Shah S , Maroufi A , Taylor M , Cope A , Belay ED , Ellington S , McCollum AM , Zilversmit Pao L , Guagliardo SAJ , Dawson P . MMWR Morb Mortal Wkly Rep 2023 72 (35) 944-948 The extent to which the 2022 mpox outbreak has affected persons without a recent history of male-to-male sexual contact (MMSC) is not well understood. During November 1-December 14, 2022, CDC partnered with six jurisdictional health departments to characterize possible exposures among mpox patients aged ≥18 years who did not report MMSC during the 3 weeks preceding symptom onset. Among 52 patients included in the analysis, 14 (27%) had a known exposure to a person with mpox, including sexual activity and other close intimate contact (eight) and household contact (six). Among 38 (73%) patients with no known exposure to a person with mpox, self-reported activities before illness onset included sexual activity and other close intimate contact (17; 45%), close face-to-face contact (14; 37%), attending large social gatherings (11; 29%), and being in occupational settings involving close skin-to-skin contact (10; 26%). These findings suggest that sexual activity remains an important route of mpox exposure among patients who do not report MMSC. |
High PrEP uptake, adherence, persistence and effectiveness outcomes among young Thai men and transgender women who sell sex in Bangkok and Pattaya, Thailand: findings from the open-label combination HIV prevention effectiveness (COPE) study

Lancet Reg Health Southeast Asia 2023 15 100217 BACKGROUND: Daily oral pre-exposure prophylaxis (PrEP) is effective in preventing HIV infection, but no study has evaluated combination prevention interventions with PrEP for transgender women (TGW) and men who have sex with men (MSM) who sell sex. METHODS: The Combination Prevention Effectiveness (COPE) study was a community-based, non-randomized implementation study in Bangkok and Pattaya, Thailand. Participants were HIV-negative MSM and TGW aged 18-26 years who reported exchanging sex with men in the prior 12 months and who met 2014 U.S. Public Health Service PrEP eligibility criteria. The intervention included quarterly HIV testing, semiannual testing for sexually transmitted infections, provision of condoms with lubricant, and the opportunity to initiate or end daily oral PrEP use at any time during study participation. Participants taking PrEP received monthly adherence counseling and short message service reminders. The primary outcome was HIV incidence rate ratio (IRR) on PrEP vs. not on PrEP. Secondary outcomes were PrEP initiation, PrEP use at 12 months, and PrEP adherence. FINDINGS: From October 2017 to August 2019, 846 participants were enrolled: 531 (62.8%) immediately initiated PrEP; 104 (12.3%) subsequently initiated PrEP, and 211 (24.9%) never initiated PrEP. Among those initiating PrEP within 30 days of enrollment; 85.9% were on PrEP at the 12-months. When taking PrEP, participants reported adherent PrEP use at 94.2% of quarterly assessments. Ten HIV seroconversions occurred without PrEP use (incidence rate [IR] = 3.42 per 100 person-years [PY]; 95% CI = 1.64-6.30), while zero cases occurred with PrEP use (IR = 0.0 per 100PY; 95% CI = 0.0-0.62), with IRR = 0.0 (95% CI = 0.0-0.22; p < 0.001). INTERPRETATION: Young Thai MSM and TGW who exchange sex can have high PrEP uptake, persistence and adherence, and low HIV incidence when offered in supportive community-based settings.

Estimating waterborne infectious disease burden by exposure route, United States, 2014
Gerdes ME , Miko S , Kunz JM , Hannapel EJ , Hlavsa MC , Hughes MJ , Stuckey MJ , Francois Watkins LK , Cope JR , Yoder JS , Hill VR , Collier SA . Emerg Infect Dis 2023 29 (7) 1357-1366 More than 7.15 million cases of domestically acquired infectious waterborne illnesses occurred in the United States in 2014, causing 120,000 hospitalizations and 6,600 deaths. We estimated disease incidence for 17 pathogens according to recreational, drinking, and nonrecreational nondrinking (NRND) water exposure routes by using previously published estimates. In 2014, a total of 5.61 million (95% credible interval [CrI] 2.97-9.00 million) illnesses were linked to recreational water, 1.13 million (95% CrI 255,000-3.54 million) to drinking water, and 407,000 (95% CrI 72,800-1.29 million) to NRND water. Recreational water exposure was responsible for 36%, drinking water for 40%, and NRND water for 24% of hospitalizations from waterborne illnesses. Most direct costs were associated with pathogens found in biofilms. Estimating disease burden by water exposure route helps direct prevention activities. For each exposure route, water management programs are needed to control biofilm-associated pathogen growth; public health programs are needed to prevent biofilm-associated diseases. |
Efficient rescue of a newly classified Ebinur lake orthobunyavirus with GFP reporter and its application in rapid antiviral screening (preprint)
Ren N , Wang F , Zhao L , Wang S , Zhang G , Li J , Zhang B , Bergeron E , Yuan Z , Xia H . bioRxiv 2022 2022.03.25.485793 Orthobunyaviruses have been reported to cause severe diseases in humans or animals, posing a threat to human health and social economy. Ebinur lake virus (EBIV) is a newly classified orthobunyavirus, which needs further intensive study and therapies to cope with its potential infection risk to human and animals. Here, through the reverse genetics system, the recombinant EBIV of wild type (rEBIV/WT) and NP-conjugated-eGFP (rEBIV/eGFP/S) were rescued for the application of the rapid antiviral drug screening. The eGFP fluorescence signal of the rEBIV/eGFP/S was stable in the process of successive passage in BHK-21 cells (over 10 passages) and this recombinant virus could replicate in various cell lines. Compared to the wild type EBIV, the rEBIV/eGFP/S caused the smaller plaques and its peak titers were lower, suggesting attenuation due to the eGFP insertion. Through the high-content screening (HCS) system, ribavirin showed an inhibitory effect on the rEBIV/eGFP/S with an EC50 of 21.91 μM, while favipiravir did not inhibit, even at high concentrations. In addition, five of ninety-six natural compounds had antiviral against EBIV. The robust reverse genetics system for EBIV will facilitate investigation into replication and assembly mechanisms and assist drug and vaccine development.Competing Interest StatementThe authors have declared no competing interest. |
Methods for Estimation of SARS-CoV-2 Seroprevalence and Reported COVID-19 Cases in U.S. Children, August 2020—May 2021 (preprint)
Couture A , Lyons BC , Mehrotra ML , Sosa L , Ezike N , Ahmed FS , Brown CM , Yendell S , Azzam IA , Katić BJ , Cope A , Dickerson K , Stone J , Traxler LB , Dunn JR , Davis LB , Reed C , Clarke KEN , Flannery B , Charles MD . medRxiv 2021 2021.09.26.21263756 Background and Objectives Case-based surveillance of pediatric COVID-19 cases underestimates the prevalence of SARS-CoV-2 infections among children and adolescents. Our objectives were to: 1) estimate monthly SARS-CoV-2 antibody seroprevalence among children aged 0-17 years and 2) calculate ratios of SARS-CoV-2 infections to reported COVID-19 cases among children and adolescents in 14 U.S. states.Methods Using data from commercial laboratory seroprevalence surveys, we estimated monthly SARS-CoV-2 antibody seroprevalence among children aged 0-17 years from August 2020 through May 2021. Seroprevalence estimates were based on SARS-CoV-2 anti-nucleocapsid immunoassays from February to May 2021. We compared estimated numbers of children infected with SARS-CoV-2 by May 2021 to cumulative incidence of confirmed and probable COVID-19 cases from case-based surveillance, and calculated infection: case ratios by state and type of anti-SARS-CoV-2 nucleocapsid immunoassay used for seroprevalence testing.Results Analyses included 67,321 serum specimens tested for SARS-CoV-2 antibodies among children in 14 U.S. states. Estimated ratios of SARS-CoV-2 infections to reported confirmed and probable COVID-19 cases among children and adolescents varied by state and type of immunoassay, ranging from 0.8-13.3 in May 2021.Conclusions Through May 2021, the majority of children in selected states did not have detectable SARS-CoV-2 nucleocapsid antibodies. Case-based surveillance underestimated the number of children infected with SARS-CoV-2, however the predicted extent of the underestimate varied by state, immunoassay, and over time. Continued monitoring of pediatric SARS-CoV-2 antibody seroprevalence should inform prevention and vaccination strategies.Competing Interest StatementThe authors have declared no competing interest.Funding StatementFunding for this work was supported by CDC (Atlanta, Georgia).Author DeclarationsI confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.YesThe details of the IRB/oversight body that provided approval or exemption for the research described are given below:This activity was reviewed by Centers for Disease Control and Prevention and determined to be consistent with non human participant research activity.

Evaluation of public health contact tracing for mpox among gay, bisexual, and other men who have sex with men-10 US jurisdictions, May 17-July 31, 2022
Cope AB , Kirkcaldy RD , Weidle PJ , Jackson DA , Laramee N , Weber R , Rowse J , Mangla A , Fox B , Saunders KE , Taniguchi K , Usagawa L , Cahill ME , Harrington P , Ricketts EK , Harbi K , Malec L , Templin TG , Drociuk D , Hannibal T , Klos R , Bernstein KT . Am J Public Health 2023 113 (7) e1-e4 Objectives. To examine the potential impact of contact tracing to identify contacts and prevent mpox transmission among gay, bisexual, and other men who have sex with men (MSM) as the outbreak expanded. Methods. We assessed contact tracing outcomes from 10 US jurisdictions before and after access to the mpox vaccine was expanded from postexposure prophylaxis for persons with known exposure to include persons at high risk for acquisition (May 17-June 30, 2022, and July 1-31, 2022, respectively). Results. Overall, 1986 mpox cases were reported in MSM from included jurisdictions (240 before expanded vaccine access; 1746 after expanded vaccine access). Most MSM with mpox were interviewed (95.0% before vaccine expansion and 97.0% after vaccine expansion); the proportion who named at least 1 contact decreased during the 2 time periods (74.6% to 38.9%). Conclusions. During the period when mpox cases among MSM increased and vaccine access expanded, contact tracing became less efficient at identifying exposed contacts. Public Health Implications. Contact tracing was more effective at identifying persons exposed to mpox in MSM sexual and social networks when case numbers were low, and it could be used to facilitate vaccine access.

Amebic encephalitis and meningoencephalitis: an update on epidemiology, diagnostic methods, and treatment
Haston JC , Cope JR . Curr Opin Infect Dis 2023 36 (3) 186-191 PURPOSE OF REVIEW: Free-living amebae (FLA) including Naegleria fowleri , Balamuthia mandrillaris , and Acanthamoeba species can cause rare, yet severe infections that are nearly always fatal. This review describes recent developments in epidemiology, diagnosis, and treatment of amebic meningoencephalitis. RECENT FINDINGS: Despite similarities among the three pathogenic FLA, there are notable variations in disease presentations, routes of transmission, populations at risk, and outcomes for each. Recently, molecular diagnostic tools have been used to diagnose a greater number of FLA infections. Treatment regimens for FLA have historically relied on survivor reports; more data is needed about novel treatments, including nitroxoline. SUMMARY: Research to identify new drugs and guide treatment regimens for amebic meningoencephalitis is lacking. However, improved diagnostic capabilities may lead to earlier diagnoses, allowing earlier treatment initiation and improved outcomes. Public health practitioners should continue to prioritize increasing awareness and providing education to clinicians, laboratorians, and the public about amebic infections. |
Cutaneous acanthamoeba infection presenting with granulomatous vasculitis
Park M , Googe PB , Derebail VK , Saha MK , Matkovic E , Cope JR , Ali IKM , Ziemer C , Wu S . SKIN J Cutan Med 2023 7 (2) 700-704 Cutaneous acanthamoebiasis is a rare diagnosis that carries a mortality rate of over 70%.2 This disease predominantly affects immunocompromised individuals, though infections have been reported in immunocompetent individuals.2 We report a fatal case of cutaneous Acanthamoeba infection in a patient with granulomatous vasculitis on biopsy, initially thought to be antineutrophil cytoplasmic antibody (ANCA)-negative vasculitis. The patient primarily presented with ulcerating nasal lesions, which subsequently developed into widespread cutaneous lesions. Diagnosis was made months after presentation when amebae were identified during histopathological examination of biopsies obtained repeatedly after the patient failed to improve on standard therapies for ANCA-negative vasculitis. Treatment was unsuccessful, and the patient died due to complications of widespread Acanthamoeba infection. Cutaneous acanthamoebiasis should be considered in the differential diagnosis of granulomatous vasculitis that fails to improve on standard therapies. Early detection and treatment may improve outcomes and reduce mortality in this highly fatal infection. © 2022 THE AUTHORS. Published by the National Society for Cutaneous Medicine. |
Case of primary amebic meningoencephalitis associated with surfing at an artificial surf venue: Environmental investigation
Miko S , Cope JR , Hlavsa MC , Ali IKM , Brown TW , Collins JP , Greeley RD , Kahler AM , Moore KO , Roundtree AV , Roy S , Sanders LL , Shah V , Stuteville HD , Mattioli MC . ACS ES T Water 2022 Naegleria fowleri is a thermophilic ameba found in freshwater that causes primary amebic meningoencephalitis (PAM) when it enters the nose and migrates to the brain. In September 2018, a 29-year-old man died of PAM after traveling to Texas. We conducted an epidemiologic and environmental investigation to identify the water exposure associated with this PAM case. The patients most probable water exposure occurred while surfing in an artificial surf venue. The surf venue water was not filtered or recirculated; water disinfection and water quality testing were not documented. N. fowleri and thermophilic amebae were detected in recreational water and sediment samples throughout the facility. Codes and standards for treated recreational water venues open to the public could be developed to address these novel venues. Clinicians and public health officials should also consider novel recreational water venues as a potential exposure for this rare amebic infection. Not subject to U.S. Copyright.

Cronobacter sakazakii Infections in Two Infants Linked to Powdered Infant Formula and Breast Pump Equipment - United States, 2021 and 2022.
Haston JC , Miko S , Cope JR , McKeel H , Walters C , Joseph LA , Griswold T , Katz LS , Andújar AA , Tourdot L , Rounds J , Vagnone P , Medus C , Harris J , Geist R , Neises D , Wiggington A , Smith T , Im MS , Wheeler C , Smith P , Carleton HA , Lee CC . MMWR Morb Mortal Wkly Rep 2023 72 (9) 223-226 Cronobacter sakazakii, a species of gram-negative bacteria belonging to the Enterobacteriaceae family, is known to cause severe and often fatal meningitis and sepsis in young infants. C. sakazakii is ubiquitous in the environment, and most reported infant cases have been attributed to contaminated powdered infant formula (powdered formula) or breast milk that was expressed using contaminated breast pump equipment (1-3). Previous investigations of cases and outbreaks have identified C. sakazakii in opened powdered formula, breast pump parts, environmental surfaces in the home, and, rarely, in unopened powdered formula and formula manufacturing facilities (2,4-6). This report describes two infants with C. sakazakii meningitis reported to CDC in September 2021 and February 2022. CDC used whole genome sequencing (WGS) analysis to link one case to contaminated opened powdered formula from the patient's home and the other to contaminated breast pump equipment. These cases highlight the importance of expanding awareness about C. sakazakii infections in infants, safe preparation and storage of powdered formula, proper cleaning and sanitizing of breast pump equipment, and using WGS as a tool for C. sakazakii investigations. |
(Mis)perception and use of unsterile water in home medical devices, PN View 360+ Survey, United States, August 2021(1)
Miko S , Collier SA , Burns-Lynch CE , Andújar AA , Benedict KM , Haston JC , Hough CO , Cope JR . Emerg Infect Dis 2023 29 (2) 397-401 Tap water is not sterile, and its use in home medical devices can result in infections from waterborne pathogens. However, many participants in a recent survey in the United States said tap water could safely be used for home medical devices. These results can inform communication materials to reduce the high consequence of infections. |
The epidemiology and clinical features of non-keratitis acanthamoeba infections in the United States, 1956-2020
Haston JC , O'Laughlin K , Matteson K , Roy S , Qvarnstrom Y , Ali IKM , Cope JR . Open Forum Infect Dis 2023 10 (1) ofac682 BACKGROUND: Acanthamoeba is a free-living ameba that can cause severe disease affecting the central nervous system, skin, sinuses, and other organs, particularly in immunocompromised individuals. These rare but severe infections are often fatal, yet incompletely described. METHODS: Cases included were either reported to the Centers for Disease Control and Prevention (CDC) Free-Living Ameba program or published in scientific literature. Characteristics of all patients in the United States with laboratory-confirmed non-keratitis Acanthamoeba infections were described using descriptive statistics, and associations with survival were determined using χ(2) and Fisher exact tests. RESULTS: Of 173 patients identified, 71% were male and the median age was 44 years (range, 0-87 years). Of these, 26 (15%) survived. Most patients (88%) had at least 1 immunocompromising condition, most commonly human immunodeficiency virus (39%), cancer (28%), and solid organ or hematopoietic stem cell transplant (28%). Granulomatous amebic encephalitis (GAE) was the most common disease presentation (71%). Skin (46%), sinuses (29%), lungs (13%), and bone (6%) were also involved. Nearly half of patients (47%) had involvement of >1 organ system. Survival was less frequent among those with GAE (3%, P < .001) compared with cutaneous disease, rhinosinusitis, or multiorgan disease not including GAE. Of 7 who received the currently recommended treatment regimen, 5 (71%) survived. CONCLUSIONS: Non-keratitis Acanthamoeba infections occur primarily in immunocompromised individuals and are usually fatal. Survival may be associated with disease presentation and treatment. Providers who care for at-risk patients should be aware of the various disease manifestations to improve early recognition and treatment. |
Pandemic isolation and mental health among children
Brannen DE , Wynn S , Shuster J , Howell M . Disaster Med Public Health Prep 2023 17 1-19 OBJECTIVE: Mental health issues increased during the COVID-19 pandemic, especially among children. Our past research efforts found that surveillance data can address a variety of health concerns; that personal psychological awareness impacted ability to cope, and mental health outcomes were improved when survivors were triaged to mental health countermeasures. To build upon our public health efforts we wanted to see if increased screen time due to remote learning caused by the pandemic influenced school aged children's mental health. METHODS: With the hypothesis that excessive time spent isolated during remote learning increased the amount of mental health events in children, we conducted a public health surveillance project on actual diagnoses rather than just symptoms, controlling for historical mental health and emotional disorders. RESULTS: The entire cohort of children ages 6 to 17 years were studied over time before and during the pandemic for their medically diagnosed mental health and emotional outcomes by the amount of pandemic induced social isolation. CONCLUSIONS: After controlling for historical diagnoses and the rate of COVID-19, the effect of pandemic induced social isolation had a linear increase on the amount of anxiety, resulting in a four-fold increase in pandemic social isolation-induced anxiety. |
Efficient rescue of a newly classified Ebinur lake orthobunyavirus with GFP reporter and its application in rapid antiviral screening.
Ren N , Wang F , Zhao L , Wang S , Zhang G , Li J , Zhang B , Wang J , Bergeron E , Yuan Z , Xia H . Antiviral Res 2022 207 105421 Orthobunyaviruses have been reported to cause severe diseases in humans or animals, posing a potential threat to human health and socio-economy. Ebinur lake virus (EBIV) is a newly classified orthobunyavirus, which can induce the histopathogenic change and even the high mortality of infected BALB/c mice. Therefore, it is needed to further study the viral replication and pathogenesis, and develop the therapies to cope with its potential infection to human or animals. Here, through the reverse genetics system, the recombinant EBIV of wild type (rEBIV/WT) and NP-conjugated-eGFP (rEBIV/eGFP/S) were rescued for the application of the high-content screening (HCS) of antiviral drug. The eGFP fluorescence signal of the rEBIV/eGFP/S was stable in the process of successive passage in BHK-21 cells (over 10 passages) and this recombinant virus could replicate in various cell lines. Compared to the wild type EBIV, the rEBIV/eGFP/S caused the smaller plaques (diameter around 1 mm on 3 dpi) and lower peak titers (10(5) PFU/mL), suggesting attenuation due to the eGFP insertion. Through the high-content screening (HCS) system, two antiviral compounds, ribavirin and favipiravir, which previously reported to have effect to some bunyavirus were tested firstly. Ribavirin showed an inhibitory effect on the rEBIV/eGFP/S (EC50 = 14.38 μM) as our expect, while favipiravir with no inhibitory effect even using high doses. Furthermore, Tyrphostin A9 (EC50 = 0.72 μM for rEBIV/eGFP/S, EC50 = 0.05 μM for EBIV-WT) and UNC0638 (EC50 = 1.26 μM for rEBIV/eGFP/S, EC50 = 1.10 μM for rEBIV/eGFP/S) were identified with strong antiviral effect against EBIV in vitro from 150 antiviral compounds. In addition, the time-of-addition assay indicated that Tyrphostin A9 worked in the stage of viral post-infection, and the UNC0638 in all pre-, co-, and post-infection stages. This robust reverse genetics system will facilitate the investigation into the studying of viral replication and assembly mechanisms, and the development of drug and vaccine for EBIV in the future. |
Developing sentinel surveillance for chlamydia and gonorrhea using test results from routine screening during pregnancy
Lazenby GB , Korte JE , Pekar E , Peterman TA , Cope AB . Sex Transm Dis 2022 50 (1) 21-27 BACKGROUND: Interpretation of case-based surveillance of chlamydia and gonorrhea is limited by the lack of negative tests for comparison. We sought to develop a sustainable electronic health record (EHR)-based approach to disease surveillance in a sentinel population of pregnant persons. METHODS: We conducted a one-year assessment of sexually transmitted infections (STIs) in persons receiving at least one pregnancy-related visit within our university medical center. Data were obtained using EHR analytic structured query language code (SQL). Patients were categorized by whether they had an STI test during pregnancy and if screened, by the STI test results (positive or negative). We assessed screening and positivity by demographic using bivariate analyses. Predictors of a positive STI test were determined using logistic regression. RESULTS: We identified 4,553 persons who received pregnancy care from January 1 to December 31, 2021. Seventy-six percent (n, 3483) of persons were screened for an STI during pregnancy. Those who identified as white or had private insurance were less likely to have a chlamydia test. Among persons screened, Trichomonas was the most commonly detected STI (5%, 141/2,698) followed by chlamydia (4%, 135/3,456), and gonorrhea (0.7% 24/3,468). Predictors of a positive STI test during pregnancy were Black race [adjusted odds ratio (aOR) 6.0 (95% Confidence Interval 4.2-8.7)], age 25 [aOR 2.5 (1.9-3.3)], and public insurance [aOR 1.6 (1.2-2.1)]. CONCLUSIONS: We demonstrated that EHRs can be utilized to assess gonorrhea and chlamydia positivity. These methods could potentially be applied in other jurisdictions to improve the understanding of national STI surveillance. |
Social vulnerability and disasters: development and evaluation of a CONVERGE training module for researchers and practitioners
Adams RM , Evans C , Wolkin A , Thomas T , Peek L . Disaster Prev Manag 2022 31 (6) 13-29 Purpose: Social vulnerability in the context of disaster management refers to the sociodemographic characteristics of a population and the physical, social, economic, and environmental factors that increase their susceptibility to adverse disaster outcomes and capacity to anticipate, cope with, resist, and recover from disaster events. Because disasters do not impact people equally, researchers, public health practitioners, and emergency managers need training to meet the complex needs of vulnerable populations. Design/methodology/approach: To address gaps in current education, the CONVERGE initiative, headquartered at the Natural Hazards Center at the University of Colorado Boulder, developed the Social Vulnerability and Disasters Training Module. This free online course draws on decades of research to examine the factors that influence social vulnerability to disasters. Examples of studies and evidence-based programs are included to illuminate common methods for studying social vulnerability and ways that research can guide practice. To evaluate the module, all trainees completed a pre- and post-training questionnaire. Findings: Between July 2019 and September 2021, 1,089 people completed the module. Wilcoxon signed rank tests demonstrated a significant perceived increase in self-rated knowledge, skills, and attitudes (KSA). Students, members of historically underrepresented populations, and those new to or less experienced in the field, had the greatest perceived increase. Practical implications: This training module can help participants understand the specific needs of socially vulnerable populations to help reduce human suffering from disasters. Originality/value: This article describes a novel web-based training and offers evaluation data showing how it can help educate a broad hazards and disaster workforce on an important topic for disaster management. © 2022, Rachel Marie Adams, Candace Evans, Amy Wolkin, Tracy Thomas and Lori Peek. |

Sex Transm Dis 2022 49 (8) 576-581 BACKGROUND: Shigella species, which cause acute diarrheal disease, are transmitted via fecal-oral and sexual contact. To better understand the overlapping populations affected by Shigella infections and sexually transmitted infections (STIs) in the United States, we examined the occurrence of reported STIs within 24 months among shigellosis case-patients. METHODS: Culture-confirmed Shigella cases diagnosed during 2007-2016 among residents of six U.S. jurisdictions were matched to reports of STIs (chlamydia, gonorrhea, and all stages of syphilis) diagnosed 12 months before or after the shigellosis case. We examined epidemiologic characteristics and reported temporal trends of Shigella cases by sex and species. RESULTS: During 2007-2016, 10,430 shigellosis cases were reported. The annual number of reported shigellosis cases across jurisdictions increased 70%, from 821 cases in 2007 to 1,398 cases in 2016; males saw a larger increase compared to females. Twenty percent of male shigellosis case-patients had an STI reported in the reference period, versus 4% of female case-patients. The percentage of male shigellosis case-patients with an STI increased from 11% (2007) to 28% (2016); the overall percentage among females remained low. CONCLUSIONS: We highlight the substantial proportion of males with shigellosis who were diagnosed with STIs within 24 months and the benefit of matching data across programs. STI screening may be warranted for male shigellosis case-patients. |

Open Forum Infect Dis 2022 9 (3) ofac044 BACKGROUND: Case-based surveillance of pediatric coronavirus disease 2019 (COVID-19) cases underestimates the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections among children and adolescents. Our objectives were to estimate monthly SARS-CoV-2 antibody seroprevalence and calculate ratios of SARS-CoV-2 infections to reported COVID-19 cases among children and adolescents in 8 US states. METHODS: Using data from the Nationwide Commercial Laboratory Seroprevalence Survey, we estimated monthly SARS-CoV-2 antibody seroprevalence among children aged 0-17 years from August 2020 through May 2021. We calculated and compared cumulative incidence of SARS-CoV-2 infection extrapolated from population-standardized seroprevalence of antibodies to SARS-CoV-2, cumulative COVID-19 case reports since March 2020, and infection-to-case ratios among persons of all ages and children aged 0-17 years for each state. RESULTS: Of 41 583 residual serum specimens tested, children aged 0-4, 5-11, and 12-17 years accounted for 1619 (3.9%), 10 507 (25.3%), and 29 457 (70.8%), respectively. Median SARS-CoV-2 antibody seroprevalence among children increased from 8% (range, 6%-20%) in August 2020 to 37% (range, 26%-44%) in May 2021. Estimated ratios of SARS-CoV-2 infections to reported COVID-19 cases in May 2021 ranged by state from 4.7-8.9 among children and adolescents to 2.2-3.9 for all ages combined. CONCLUSIONS: Through May 2021 in selected states, the majority of children with serum specimens included in serosurveys did not have evidence of prior SARS-CoV-2 infection. Case-based surveillance underestimated the number of children infected with SARS-CoV-2 more than among all ages. Continued monitoring of pediatric SARS-CoV-2 antibody seroprevalence should inform prevention and vaccination strategies. |

Infect Control Hosp Epidemiol 2022 43 (11) 1-30 OBJECTIVE: Determine the incidence of SARS-CoV-2 infection among healthcare personnel (HCP) and assess occupational risks for SARS-CoV-2 infection. DESIGN: Prospective cohort of HCP followed for 6-months from May-December 2020. SETTING: Large academic healthcare system including four hospitals and affiliated clinics in Atlanta, GA. PARTICIPANTS: HCP, including those with and without direct patient care activities, working during the COVID-19 pandemic. METHODS: Incident SARS-CoV-2 infections were determined through serologic testing for SARS-CoV-2 IgG at enrollment, 3 and 6 months. HCP completed monthly surveys regarding occupational activities. Multivariable logistic regression was used to identify occupational factors that increased the risk of SARS-CoV-2 infection. RESULTS: Of the 304 evaluable HCP that were seronegative at enrollment, 26 (9%) seroconverted for SARS-CoV-2 IgG by 6 months. Participants self-identified predominantly as White (n=219, 73%), nurses (n=119, 40%), and working in inpatient medical/surgical floors (n=121, 40%). In a multivariable analysis, HCP who identified as Black were more likely to seroconvert than HCP who identified as White (odds ratio 4.5, 95% confidence interval 1.3-14.2). Increased risk for SARS-CoV-2 infection was not identified for any occupational activity, including spending >50% of a typical shift at a patient's bedside, working in COVID-19 units, or performing/being present for aerosol generating procedures (AGPs). CONCLUSIONS: In our study cohort of HCP working in an academic healthcare system, <10% had evidence of SARS-CoV-2 infection over six months. No specific occupational activities were identified as increasing risk for SARS-CoV-2 infection. |

JAMA Netw Open 2022 5 (2) e2147053 IMPORTANCE: New symptoms and conditions can develop following SARS-CoV-2 infection. Whether they occur more frequently among persons with SARS-CoV-2 infection compared with those without is unclear. OBJECTIVE: To compare the prevalence of new diagnoses of select symptoms and conditions between 31 and 150 days after testing among persons who tested positive vs negative for SARS-CoV-2. DESIGN, SETTING, AND PARTICIPANTS: This cohort study analyzed aggregated electronic health record data from 40 health care systems, including 338 024 persons younger than 20 years and 1 790 886 persons aged 20 years or older who were tested for SARS-CoV-2 during March to December 2020 and who had medical encounters between 31 and 150 days after testing. MAIN OUTCOMES AND MEASURES: International Statistical Classification of Diseases, Tenth Revision, Clinical Modification codes were used to capture new symptoms and conditions that were recorded 31 to 150 days after a SARS-CoV-2 test but absent in the 18 months to 7 days prior to testing. The prevalence of new symptoms and conditions was compared between persons with positive and negative SARS-CoV-2 tests stratified by age (20 years or older and young than 20 years) and care setting (nonhospitalized, hospitalized, or hospitalized and ventilated). RESULTS: A total of 168 701 persons aged 20 years or older and 26 665 younger than 20 years tested positive for SARS-CoV-2, and 1 622 185 persons aged 20 years or older and 311 359 younger than 20 years tested negative. Shortness of breath was more common among persons with a positive vs negative test result among hospitalized patients (≥20 years: prevalence ratio [PR], 1.89 [99% CI, 1.79-2.01]; <20 years: PR, 1.72 [99% CI, 1.17-2.51]). Shortness of breath was also more common among nonhospitalized patients aged 20 years or older with a positive vs negative test result (PR, 1.09 [99% CI, 1.05-1.13]). Among hospitalized persons aged 20 years or older, the prevalence of new fatigue (PR, 1.35 [99% CI, 1.27-1.44]) and type 2 diabetes (PR, 2.03 [99% CI, 1.87-2.19]) was higher among those with a positive vs a negative test result. Among hospitalized persons younger than 20 years, the prevalence of type 2 diabetes (PR, 2.14 [99% CI, 1.13-4.06]) was higher among those with a positive vs a negative test result; however, the prevalence difference was less than 1%. CONCLUSIONS AND RELEVANCE: In this cohort study, among persons hospitalized after a positive SARS-CoV-2 test result, diagnoses of certain symptoms and conditions were higher than among those with a negative test result. Health care professionals should be aware of symptoms and conditions that may develop after SARS-CoV-2 infection, particularly among those hospitalized after diagnosis. |
Electromagnetic Interference (EMI) In Underground Coal Mines: a Literature Review and Practical Considerations
Zhou C , Reyes M , Girman M . Min Metall Explor 2022 39 (2) 421-431 Modern smart mining increasingly depends on the use of sophisticated electrical and electronic systems for improved safety and better productivity. With more electronic systems being introduced underground, the mining industry is facing electromagnetic compatibility (EMC) issues caused by electromagnetic energy emitted by one device adversely impacting the normal function of another. This paper provides an overview of EMC and electromagnetic interference (EMI) research for underground mining. The paper first starts with an overview of EMI in other industries applicable to mining, followed by a literature review on published EMI research pertaining to mining applications. Some representative EMI incidences and related EMI legislation in mining are reviewed. Finally, mitigation strategies that can be potentially used to cope with EMI issues are discussed and some practical considerations and best practices to overcome EMI in mining are provided. This paper is aimed at helping the mining industry to better understand the challenges posed by EMI and to promote EMC in underground coal mines. © 2022, This is a U.S. government work and not under copyright protection in the U.S.; foreign copyright protection may apply. |
Evaluation of Test to Stay Strategy on Secondary and Tertiary Transmission of SARS-CoV-2 in K-12 Schools - Lake County, Illinois, August 9-October 29, 2021.
Nemoto N , Dhillon S , Fink S , Holman EJ , Cope AK , Dinh TH , Meadows J , Taryal D , Akindileni F , Franck M , Gelber E , Bacci L , Ahmed S , Thomas ES , Neatherlin JC . MMWR Morb Mortal Wkly Rep 2021 70 (5152) 1778-1781 The COVID-19 pandemic has resulted in school closures and reduction of in-person learning (1). In August 2021, the Lake County Health Department (LCHD) in Illinois introduced a Test to Stay (TTS) strategy, whereby unvaccinated students, teachers, and staff members with certain school-related COVID-19 exposures could remain in school and participate in school-related extracurricular activities. Eligibility to participate in TTS required the following conditions to be met: 1) the exposure occurred while both the person with COVID-19 (index patient) and the close contact were masked; 2) the close contact remained asymptomatic, practiced consistent mask wearing, and maintained physical distancing; and 3) the close contact underwent testing for SARS-CoV-2 (the virus that causes COVID-19) on days 1, 3, 5, and 7 after exposure to the index patient. LCHD permitted kindergarten through grade 12 (K-12) schools in Lake County to implement TTS; 90 schools, representing 31 school districts in Lake County, implemented TTS during August 9-October 29, 2021. During the implementation period, 258 COVID-19 cases were reported. Among 1,035 students and staff members enrolled in TTS, the secondary attack risk (number of close contacts who received a positive SARS-CoV-2 test result within 14 days after exposure to an index patient, divided by total number of close contacts) was 1.5% (16 of 1,035). Among the 16 secondary cases identified, all were in students, and none appeared to transmit SARS-CoV-2 to other school-based contacts. However, nine tertiary cases were identified among household contacts of the 16 secondary cases, and four of the nine were fully vaccinated. Assuming a maximum of 8 missed school days for every 10-day quarantine period, up to 8,152 in-person learning days were saved among TTS participants. Implementation of TTS with other concurrent prevention strategies, including masking and physical distancing, limited further spread of SARS-CoV-2 within K-12 schools and allowed students to safely sustain in-person learning. Although vaccination remains the leading public health recommendation to protect against COVID-19 for those aged ≥5 years, schools might consider TTS as an option for allowing close contacts who are not fully vaccinated to remain in the classroom as an alternative to home quarantine. |
Electronic messaging for gonorrhea and chlamydia test result notification, improving treatment and patient satisfaction
Rahman MM , Johnson C , Whyte M , Ewell J , Cope AB , Chandler Y , Bennett TS , Gray T , Gruber D , Peterman TA . Sex Transm Dis 2021 49 (4) 257-261 BACKGROUND: Approximately 20% of chlamydia (CT) and gonorrhea (GC) cases in Louisiana are diagnosed at Parish Health Units (PHU). Patient notification of CT and GC test results involves nurses' phone calls and letters to positive patients, which is time consuming and inefficient. METHODS: In December 2018, electronic results notification was implemented in Caddo PHU using Chexout software to notify enrolled patients via text or email when test results are ready to view in a patient portal. We compared the timeliness of GC/CT results notification and treatment pre- (December 2017-November 2018) and post- (December 2018-November 2019) Chexout implementation. A random sample of patients were interviewed to assess acceptability. RESULTS: During December 2018 - November 2019, 5,432 patients were tested for CT/GC, 3,924 (72%) enrolled in Chexout, and notifications were sent to 3,884 (99%). Among CT positives, 472/568 (83%) viewed results in the portal compared to 2,451/3,356 (73%) CT negatives. Among GC positives, 300/353 (85%) viewed results compared to 2,657/3,571 (74%) GC negatives. Treatment success for CT improved from 493/670 (74%) to 506/568 (89%) and for GC from 332/409 (81%) to 325/353 (92%). Mean time to treatment decreased for CT (13.4 to 10.7 days) and GC (11.3 to 9.2 days). Enrolled patients found Chexout notification satisfactory 168/169 (99%) and easy to use 130/141 (92%). Reasons for declining electronic notification included lack of personal cell phone 55/86 (64%) and confidentiality concerns 42/86 (49%). CONCLUSIONS: Electronic messaging decreased time to notification and increased treatment success. Nurses spent less time notifying patients leaving more time for patient care. |
A qualitative assessment of factors affecting nursing home caregiving staff experiences during the COVID-19 pandemic.
Snyder RL , Anderson LE , White KA , Tavitian S , Fike LV , Jones HN , Jacobs-Slifka KM , Stone ND , Sinkowitz-Cochran RL . PLoS One 2021 16 (11) e0260055 BACKGROUND: A large portion of COVID-19 cases and deaths in the United States have occurred in nursing homes; however, current literature including the frontline perspective of staff working in nursing homes is limited. The objective of this qualitative assessment was to better understand what individual and facility level factors may have contributed to the impact of COVID-19 on Certified Nursing Assistants (CNAs) and Environmental Services (EVS) staff working in nursing homes. METHODS: Based on a simple random sample from the National Healthcare Safety Network (NHSN), 7,520 facilities were emailed invitations requesting one CNA and/or one EVS staff member for participation in a voluntary focus group over Zoom. Facility characteristics were obtained via NHSN and publicly available sources; participant demographics were collected via SurveyMonkey during registration and polling during focus groups. Qualitative information was coded using NVIVO and Excel. RESULTS: Throughout April 2021, 23 focus groups including 110 participants from 84 facilities were conducted homogenous by participant role. Staffing problems were a recurring theme reported. Participants often cited the toll the pandemic took on their emotional well-being, describing increased stress, responsibilities, and time needed to complete their jobs. The lack of consistent and systematic guidance resulting in frequently changing infection prevention protocols was also reported across focus groups. CONCLUSIONS: Addressing concerns of low wages and lack of financial incentives may have the potential to attract and retain employees to help alleviate nursing home staff shortages. Additionally, access to mental health resources could help nursing home staff cope with the emotional burden of the COVID-19 pandemic. These frontline staff members provided invaluable insight and should be included in improvement efforts to support nursing homes recovering from the impact of COVID-19 as well as future pandemic planning. |
Long-Term Symptoms Among Adults Tested for SARS-CoV-2 - United States, January 2020-April 2021.
Wanga V , Chevinsky JR , Dimitrov LV , Gerdes ME , Whitfield GP , Bonacci RA , Nji MAM , Hernandez-Romieu AC , Rogers-Brown JS , McLeod T , Rushmore J , Lutfy C , Bushman D , Koumans E , Saydah S , Goodman AB , Coleman King SM , Jackson BR , Cope JR . MMWR Morb Mortal Wkly Rep 2021 70 (36) 1235-1241 Long-term symptoms often associated with COVID-19 (post-COVID conditions or long COVID) are an emerging public health concern that is not well understood. Prevalence of post-COVID conditions has been reported among persons who have had COVID-19 (range = 5%-80%), with differences possibly related to different study populations, case definitions, and data sources (1). Few studies of post-COVID conditions have comparisons with the general population of adults with negative test results for SARS-CoV-2, the virus that causes COVID-19, limiting ability to assess background symptom prevalence (1). CDC used a nonprobability-based Internet panel established by Porter Novelli Public Services* to administer a survey to a nationwide sample of U.S. adults aged ≥18 years to compare the prevalence of long-term symptoms (those lasting >4 weeks since onset) among persons who self-reported ever receiving a positive SARS-CoV-2 test result with the prevalence of similar symptoms among persons who reported always receiving a negative test result. The weighted prevalence of ever testing positive for SARS-CoV-2 was 22.2% (95% confidence interval [CI] = 20.6%-23.8%). Approximately two thirds of respondents who had received a positive test result experienced long-term symptoms often associated with SARS-CoV-2 infection. Compared with respondents who received a negative test result, those who received a positive test result reported a significantly higher prevalence of any long-term symptom (65.9% versus 42.9%), fatigue (22.5% versus 12.0%), change in sense of smell or taste (17.3% versus 1.7%), shortness of breath (15.5% versus 5.2%), cough (14.5% versus 4.9%), headache (13.8% versus 9.9%), and persistence (>4 weeks) of at least one initially occurring symptom (76.2% versus 69.6%). Compared with respondents who received a negative test result, a larger proportion of those who received a positive test result reported believing that receiving a COVID-19 vaccine made their long-term symptoms better (28.7% versus 15.7%). Efforts to address post-COVID conditions should include helping health care professionals recognize the most common post-COVID conditions and optimize care for patients with persisting symptoms, including messaging on potential benefits of COVID-19 vaccination. |
