Investigation of an mpox outbreak affecting many vaccinated persons in Chicago, IL-March 2023-June 2023
Faherty EAG , Holly T , Ogale YP , Spencer H , Becht AM , Crisler G , Wasz M , Stonehouse P , Barbian HJ , Zelinski C , Kittner A , Foulkes D , Anderson KW , Evans T , Nicolae L , Staton A , Hardnett C , Townsend MB , Carson WC , Panayampalli SS , Hutson CL , Gigante CM , Quilter LAS , Gorman S , Borah B , Black SR , Pacilli M , Kern D , Kerins J , McCollum AM , Rao AK , Tabidze I . Clin Infect Dis 2024 BACKGROUND: After months of few mpox cases, an increased number of cases were reported in Chicago during May 2023; predominantly among fully vaccinated patients. We investigated the outbreak scope, differences between vaccinated and unvaccinated patients, and hypotheses for monkeypox virus (MPXV) infection after vaccination. METHODS: We interviewed patients and reviewed medical records to assess demographic, behavioral, and clinical characteristics, mpox vaccine status, and vaccine administration routes. We evaluated serum antibody levels after infection and compared patient viral genomes with MPXV sequences in available databases. We discussed potential vaccine compromise with partners who manufactured, handled, and administered vaccine associated with breakthrough infections. RESULTS: During March 18-June 27, 2023, we identified 49 mpox cases; 57% of these mpox patients were fully vaccinated (FV). FV patients received both JYNNEOS doses subcutaneously (57%), intradermally (7%), or via heterologous administration (36%). FV patients had more median sex partners (3, IQR=1-4) versus not fully vaccinated (NFV) patients (1, IQR=1-2). Thirty-six of 37 sequenced specimens belonged to lineage B.1.20 of clade IIb MPXV, which did not demonstrate any amino acid changes relative to B.1, the predominant lineage from May 2022. Vaccinated patients demonstrated expected humoral antibody responses; none were hospitalized. No vaccine storage excursions were identified. Approximately 63% of people at risk for mpox in Chicago were FV during this period. CONCLUSIONS: Our investigation indicated cases were likely due to frequent behaviors associated with mpox transmission, even with relatively high vaccine effectiveness and vaccine coverage. Cases after vaccination might occur in similar populations. |
SARS-cov-2 reinfection risk in persons with HIV, Chicago, Illinois, USA, 2020-2022
Teran RA , Gagner A , Gretsch S , Lauritsen J , Galanto D , Walblay K , Ruestow P , Korban C , Pacilli M , Kern D , Black SR , Tabidze I . Emerg Infect Dis 2023 29 (11) 2257-2265 Understanding if persons with HIV (PWH) have a higher risk for SARS-CoV-2 reinfection may help tailor future COVID-19 public health guidance. To determine whether HIV infection was associated with increased risk for SARS-CoV-2 reinfection, we followed adult residents of Chicago, Illinois, USA, with SARS-CoV-2 longitudinally from their first reported infection through May 31, 2022. We matched SARS-CoV-2 laboratory data and COVID-19 vaccine administration data to Chicago's Enhanced HIV/AIDS Reporting System. Among 453,587 Chicago residents with SARS-CoV-2, a total of 5% experienced a SARS-CoV-2 reinfection, including 192/2,886 (7%) PWH and 23,642/450,701 (5%) persons without HIV. We observed higher SARS-CoV-2 reinfection incidence rates among PWH (66 [95% CI 57-77] cases/1,000 person-years) than PWOH (50 [95% CI 49-51] cases/1,000 person-years). PWH had a higher adjusted rate of SARS-CoV-2 reinfection (1.46, 95% CI 1.27-1.68) than those without HIV. PWH should follow the recommended COVID-19 vaccine schedule, including booster doses. |
COVID-19 in the US-affiliated Pacific Islands: A timeline of events and lessons learned from March 2020-November 2022
Cash McGinley HL , Hancock WT , Kern-Allely S , Jenssen M , Chutaro E , Camacho J , Judicpa P , Okumura K , Muñoz N , Ademokun OM , Brostrom R . PLOS Glob Public Health 2023 3 (8) e0002052 The US-Affiliated Pacific Islands (USAPIs) experience many health disparities, including high rates of non-communicable disease and limited health resources, making them particularly vulnerable when SARS-CoV-2 began circulating globally in early 2020. Therefore, many USAPIs closed their borders early during the COVID-19 pandemic to give them more time to prepare for community transmission. Routine virtual meetings were established and maintained throughout the pandemic to support preparedness and response efforts and to share information among USAPIs and support partners. Data collected from these regular virtual meetings were gathered and disseminated through routine regional situational reports. These situational reports from March 27, 2020 to November 25, 2022 were reviewed to develop a quantitative dataset with qualitative notes that were used to summarize the COVID-19 response in the USAPIs. The initial surges of COVID-19 in the USAPIs ranged from August 2020 in Guam to August 2022 in the Federated States of Micronesia. This prolonged time between initial surges in the region was due to varying approaches regarding travel requirements, including fully closed borders, repatriation efforts requiring pre-travel quarantine and testing, quarantine requirements upon arrival only, and vaccine mandates. Delaying community transmission allowed USAPIs to establish testing capacity, immunize large proportions of their populations, and use novel COVID-19 therapeutics to reduce severe disease and mortality. Other essential components to support the USAPI regional COVID-19 response efforts included strong partnership and collaboration, regional information sharing and communication efforts, and trust in health leadership among community members. Valuable lessons learned from the USAPIs during the COVID-19 pandemic can be used to continue to strengthen systems within the region and better prepare for future public health emergencies. |
Extragenital gonorrhoea, chlamydia, and HIV co-infection in people with mpox
Herrera K , Lyang J , Holly T , Faherty EA , Luc C , Korban C , Kern D , Tabidze I . Lancet Infect Dis 2023 23 (9) e334-e336 High prevalence of sexually transmitted infections, including gonorrhoea (28%), chlamydia (25%), syphilis (8%), and HIV (38%) co-infections have been reported in the 2022 mpox outbreak,1 which has disproportionately affected men who have sex with men and minoritised racial and ethnic groups.2 Although the outbreak has receded, a modelling analysis predicts that most jurisdictions in the USA could be at risk of resurgence without continued vaccination efforts.3 In previous mpox outbreaks, co-infection with HIV has been associated with poor mpox health outcomes.1, 4 Furthermore, among people with mpox in eight jurisdictions in the USA in 2022, those with HIV co-infection were more likely to report severe symptoms compared with those without HIV co-infection.1 Unprotected anal intercourse confers a significant risk for HIV acquisition as the rectal membrane is susceptible to infection due to its thin and friable nature.5 Previous gonorrhoea and chlamydia diagnoses are also established risk factors for HIV acquisition.6 These findings, along with clinical manifestations of mpox at rectal, genital, and oral sites warrant further investigation. This Correspondence aims to explore predictors, including gonorrhoea and chlamydia sites of infection in the previous 12 months of mpox diagnosis, and HIV co-infection among people with mpox in Chicago, USA. It is hypothesised that a previous or current rectal site of gonorrhoea or chlamydia infection will be associated with an increased prevalence of HIV and mpox co-infection. |
Disaster preparedness among women with a recent live birth in Hawaii, a cross-sectional study, results from the Pregnancy Risk Assessment Monitoring System (PRAMS), 2016 (preprint)
Strid P , Fok CCT , Zotti M , Shulman HB , Awakuni J , House LD , Morrow B , Kern J , Shim M , Ellington SR . medRxiv 2021 2021.04.14.21255501 Objectives This study examines emergency preparedness behaviors among women with a recent live birth in Hawaii.Methods Using the 2016 Hawaii Pregnancy Risk Assessment Monitoring Survey we estimated weighted prevalence of eight preparedness behaviors.Results Among 1010 respondents (weighted response rate=56.3%), 79.3% reported at least one preparedness behavior and 11.2% performed all eight behaviors. The prevalence of women with a recent live birth in Hawaii reporting preparedness behaviors includes: 63.0% (95% CI: 58.7-67.1%) having enough supplies at home for at least seven days, 41.3% (95% CI: 37.1-45.6%) having an evacuation plan for their child(ren), 38.7% (95% CI: 34.5, 43.0) having methods to keep in touch, 37.8% (95% CI: 33.7, 42.1) having an emergency meeting place, 36.6% (95% CI: 32.6, 40.9) having an evacuation plan to leave home, 34.9% (95% CI: 30.9, 39.2) having emergencies supplies to take with if they have to leave quickly, 31.8% (95% CI: 27.9, 36.0) having copies of important documents, 31.6% (95% CI: 27.7, 35.8) having practiced what to do.Conclusion One in ten women practiced all eight behaviors indicating more awareness efforts are needed among this at-risk population in Hawaii. Hawaii can measure the effect of interventions to increase preparedness by tracking this question over time.“What is already known on this subject?”Preparedness is associated with reduced vulnerability, and postpartum women are considered an at-risk population in the post-disaster period with special clinical needs. One prior study has assessed disaster preparedness among postpartum women.“What this study adds?”This is the first study to describe a methodology to analyze the eight-part PRAMS emergency preparedness question. Among recently postpartum women in Hawaii, about 80% practiced at least one of eight emergency preparedness measures assessed and about 10% practiced all behaviors.Competing Interest StatementThe authors have declared no competing interest.Funding StatementCDC provides annual funding to participating PRAMS sites through a cooperative agreement.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:Ethics approval PRAMS protocol has been reviewed and approved by Centers for Disease Control and Preventions Institutional Review Board and approved as human subjects research (HSR #2233).

Notes from the field: Emergence of an mpox cluster primarily affecting persons previously vaccinated against mpox - Chicago, Illinois, March 18-June 12, 2023
Faherty EAG , Holly T , Ogale YP , Crisler G , Becht A , Kern D , Nicolae L , Spencer H , Wasz M , Kerins JL , Kittner A , Staton A , Hardnett C , Hutson C , Gigante CM , Quilter L , Kracalik I , Black S , McCollum AM , Rao AK , Tabidze I . MMWR Morb Mortal Wkly Rep 2023 72 (25) 696-698 During April 17–May 5, 2023, 13 monkeypox (mpox) cases were reported to the Chicago Department of Public Health (CDPH) after 2 months during which only a single case had been reported. The cluster was remarkable because it comprised more than 10 cases at a time when sporadic cases or small clusters (i.e., involving fewer than three cases) were being reported in the United States, and >69% of the persons in this cluster had received 2 doses of JYNNEOS or 1 dose of ACAM2000 vaccine.* Some cases among persons who received doses of JYNNEOS vaccine are expected to occur based on vaccine effectiveness data (1,2); however, the observed proportion of cases among persons who had received 2 doses of JYNNEOS or 1 dose of ACAM2000 in this cluster was unusual. This increase in cases before large summer events scheduled nationwide and in Chicago raised concerns about possible future case increases. | | On May 9, 2023, CDPH issued a health alert,† urging clinicians to remain vigilant for mpox cases and encouraging vaccination for persons at risk for mpox.§ CDPH and CDC launched an investigation to 1) determine the cluster’s scope and etiology by evaluating patients’ commonalities, JYNNEOS¶ vaccine cold-chain management, whole genome sequencing of clinical samples, and serologic immune response after infections, and to 2) identify important risk factors for mpox exposure to guide prevention efforts. This activity was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy.** |
Cardiology care and loss to follow-up among adults with congenital heart defects in CH STRONG
Andrews JG , Strah D , Downing KF , Kern MC , Oster ME , Seckeler MD , Goudie A , Nembhard WN , Farr SL , Klewer SE . Am J Cardiol 2023 197 42-45 Many of the estimated 1.4 million adults with congenital heart defects (CHDs) in the United States are lost to follow-up (LTF) despite recommendations for ongoing cardiology care. Using 2016 to 2019 CH STRONG (Congenital Heart Survey To Recognize Outcomes, Needs, and well-beinG) data, we describe cardiac care among community-based adults with CHD, born in 1980 to 1997, identified through state birth defects registries. Our estimates of LTF were standardized to the CH STRONG eligible population and likely more generalizable to adults with CHD than clinic-based data. Half of our sample were LTF and more than 45% had not received cardiology care in over 5 years. Of those who received care, only 1 in 3 saw an adult CHD physician at their last encounter. Not knowing they needed to see a cardiologist, being told they no longer needed cardiology care, and feeling "well" were the top reasons for LTF, and only half of respondents report doctors discussing the need for cardiac follow-up. |
Assessing changes in insurance status and access to care among patients attending Chicago STI specialty clinics from 2013-2019
Korban C , Tabidze I , Broussard D , Cruz Y , Kern D , Mehta SD . Sex Transm Dis 2022 50 (3) 161-166 BACKGROUND: Public STI clinics are safety net providers for uninsured and underinsured individuals but are at risk for closure due to declining budgets and shifting priorities. This study sought to assess changes in insurance status and access to preventive care among public STI clinic patients following immediate and long-term implementation of the Affordable Care Act (ACA). MATERIALS AND METHODS: Patients receiving care in STI clinics administered by Chicago Department of Public Health were asked to complete an anonymous survey in 2013, 2014, and 2019. We estimated the prevalence rate ratio (PRR) of (1) being insured and (2) having access to preventive care over time, adjusted for age, race, and gender/sexual orientation, and employment status. RESULTS: Among 1,711 respondents, compared to 2013 patients, patients were 1.41 (adjusted PRR) times more likely to report being insured in 2014 (95% CI: 1.11-1.77), and 1.24 (aPRR) times more likely to report being insured in 2019 (95% CI: 0.99-1.55). After adjusting for other significant variables (age, sex and orientation, and insurance status), reported access to preventive care increased by 34% among respondents in 2019 as compared to 2013 (aPRR = 1.34). Unsurprisingly, being insured was associated with increased preventive care access (aPRR = 1.78). CONCLUSIONS: Even after implementation of the ACA, survey of public STI clinic patients in Chicago found a sizeable proportion of individuals without insurance, and many lacked access to preventive care, highlighting the continued need for these safety net clinics to provide STI care. |
A description of suspected concussions in football-related activities among K-12 students in Utah
Waltzman D , Sarmiento K , Ferrell D , Kern V , Roghaar C . J Sch Nurs 2022 10598405221138731 The circumstances and nature of concussions among youth who play tackle, flag, or touch football are not well understood. This study used data from Utah's Student Injury Reporting System (SIRS) to explore suspected concussions among K-12 students sustained during participation in football-related activities (tackle, flag, or touch football). Descriptive statistics and chi-square analyses showed that 54.7% of suspected concussions due to football-related activity were among elementary and middle school and 41.3% were among high school students. Most suspected concussions resulted from being struck by or against something (81.9%) and occurred during school-sanctioned games and practices (37.9%), lunch, lunch recess, and recess (34.8%), or physical education class (22.7%). The type of school activity and context for suspected concussions varied by school level. School nurses and others in Utah may use study findings to customize concussion prevention efforts by school level and activity. |
Disaster preparedness among women with a recent live birth in Hawaii - results from the Pregnancy Risk Assessment Monitoring System (PRAMS), 2016
Strid P , Fok CCT , Zotti M , Shulman HB , Awakuni J , House LD , Morrow B , Kern J , Shim M , Ellington SR . Disaster Med Public Health Prep 2021 16 (5) 1-10 OBJECTIVE: The aim of this study was to examine emergency preparedness behaviors among women with a recent live birth in Hawaii. METHODS: Using the 2016 Hawaii Pregnancy Risk Assessment Monitoring System, we estimated weighted prevalence of 8 preparedness behaviors. RESULTS: Among 1010 respondents (weighted response rate, 56.3%), 79.3% reported at least 1 preparedness behavior, and 11.2% performed all 8 behaviors. The prevalence of women with a recent live birth in Hawaii reporting preparedness behaviors includes: 63.0% (95% CI: 58.7-67.1%) having enough supplies at home for at least 7 days, 41.3% (95% CI: 37.1-45.6%) having an evacuation plan for their child(ren), 38.7% (95% CI: 34.5-43.0%) having methods to keep in touch, 37.8% (95% CI: 33.7-42.1%) having an emergency meeting place, 36.6% (95% CI: 32.6-40.9%) having an evacuation plan to leave home, 34.9% (95% CI: 30.9-39.2%) having emergency supplies to take with them if they have to leave quickly, 31.8% (95% CI: 27.9-36.0%) having copies of important documents, and 31.6% (95% CI: 27.7-35.8%) having practiced what to do during a disaster. CONCLUSIONS: One in 10 women practiced all 8 behaviors, indicating more awareness efforts are needed among this population in Hawaii. The impact of preparedness interventions implemented in Hawaii can be tracked with this question over time. |
Notes from the field: First evidence of locally acquired dengue since 1944 - Guam, 2019
Kern-Allely S , Pobutsky A , Hancock WT . MMWR Morb Mortal Wkly Rep 2020 69 (13) 387-388 On September 9, 2019, a resident of Guam with no travel history experienced a dengue-like illness that was reported to the Guam Department of Public Health and Social Services (DPHSS). On September 10, 2019, the Guam Public Health Laboratory (PHL) detected dengue virus 3 (DENV-3) in the patient’s serum specimen by reverse transcription–polymerase chain reaction (RT-PCR). This was the first detection of a locally acquired dengue case on Guam since 1944 (1). On September 11, Guam DPHSS initiated enhanced surveillance for suspected dengue cases and distributed a health alert to all health care providers with instructions for receiving dengue testing at the Guam PHL. On September 13, the Government of Guam declared a state of emergency to assist Guam DPHSS (2). Primary emergency response efforts included visits to homes within a 656-ft (200-m) radius of the primary residence of persons with confirmed locally acquired cases to provide educational materials, conduct case finding, implement mosquito source reduction, set traps for mosquito surveillance, and apply pesticides at homes of consenting residents. Public education efforts included billboards, pamphlets, and educational sessions held in schools and other community areas at risk. Updates on the clinical management of dengue using guidelines from CDC* and the World Health Organization (3) were delivered to all hospitals, medical societies, and most outpatient clinics. |
Vital Signs: Status of human immunodeficiency virus testing, viral suppression, and HIV preexposure prophylaxis - United States, 2013-2018
Harris NS , Johnson AS , Huang YA , Kern D , Fulton P , Smith DK , Valleroy LA , Hall HI . MMWR Morb Mortal Wkly Rep 2019 68 (48) 1117-1123 BACKGROUND: Approximately 38,000 new human immunodeficiency virus (HIV) infections occur in the United States each year; these infections can be prevented. A proposed national initiative, Ending the HIV Epidemic: A Plan for America, incorporates three strategies (diagnose, treat, and prevent HIV infection) and seeks to leverage testing, treatment, and preexposure prophylaxis (PrEP) to reduce new HIV infections in the United States by at least 90% by 2030. Targets to reach this goal include that at least 95% of persons with HIV receive a diagnosis, 95% of persons with diagnosed HIV infection have a suppressed viral load, and 50% of those at increased risk for acquiring HIV are prescribed PrEP. Using surveillance, pharmacy, and other data, CDC determined the current status of these three initiative strategies. METHODS: CDC analyzed HIV surveillance data to estimate annual number of new HIV infections (2013-2017); estimate the percentage of infections that were diagnosed (2017); and determine the percentage of persons with diagnosed HIV infection with viral load suppression (2017). CDC analyzed surveillance, pharmacy, and other data to estimate PrEP coverage, reported as a percentage and calculated as the number of persons who were prescribed PrEP divided by the estimated number of persons with indications for PrEP. RESULTS: The number of new HIV infections remained stable from 2013 (38,500) to 2017 (37,500) (p = 0.448). In 2017, an estimated 85.8% of infections were diagnosed. Among 854,206 persons with diagnosed HIV infection in 42 jurisdictions with complete reporting of laboratory data, 62.7% had a suppressed viral load. Among an estimated 1.2 million persons with indications for use of PrEP, 18.1% had been prescribed PrEP in 2018. CONCLUSION: Accelerated efforts to diagnose, treat, and prevent HIV infection are needed to achieve the U.S. goal of at least 90% reduction in the number of new HIV infections by 2030. |
Increases in the competitive fitness of West Nile virus isolates after introduction into California
Worwa G , Hutton AA , Frey M , Duggal NK , Brault AC , Reisen WK . Virology 2017 514 170-181 To investigate the phenotypic evolution of West Nile virus (WNV) in California, we competed sixteen isolates made during 2007-08 against COAV997-5nt, a genetically marked clone from the founding 2003 California isolate COAV997-2003. Using in vivo fitness competitions in House Finches (HOFI) and Culex tarsalis mosquitoes, we found that the majority of WNV WN02 and SW03 genotype isolates exhibited elevated replicative fitness in both hosts compared to COAV997-5nt. Increased replicative capacity in HOFIs was not associated with increased mortality, indicating that these isolates had not gained avian virulence. One WN02 isolate from Coachella Valley, a region geographically close to the isolation of COAV997, showed neutral fitness in HOFIs and reduced fitness in Cx. tarsalis. Two isolates from Kern County and Sacramento/Yolo County out-competed COAV997-nt in HOFIs, but were transmitted less efficiently by Cx. tarsalis. Competition demonstrated neutral or increased fitness that appeared independent of both WN02 and SW03 genotypes. |
Description of a mass poisoning in a rural district in Mozambique: The first documented bongkrekic acid poisoning in Africa
Gudo ES , Cook K , Kasper AM , Vergara A , Salomao C , Oliveira F , Ismael H , Saeze C , Mosse C , Fernandes Q , Viegas SO , Baltazar CS , Doyle TJ , Yard E , Steck A , Serret M , Falconer TM , Kern SE , Brzezinski JL , Turner JA , Boyd BL , Jani IV . Clin Infect Dis 2017 66 (9) 1400-1406 Background: On January 9, 2015, in a rural town in Mozambique, over 230 people became sick and 75 died from an illness linked to drinking pombe, a traditional alcoholic beverage. Methods: An investigation was conducted to identify cases and determine the cause of the outbreak. A case was defined as any resident of Chitima who developed any new or unexplained neurologic, gastrointestinal, or cardiovascular symptom from January 9 at 6:00 a.m. through January 12. We conducted medical record reviews; healthcare worker and community surveys; anthropological and toxicological investigations of local medicinal plants and commercial pesticides; and laboratory testing of the suspect and control pombe. Results: We identified 234 cases; 75 (32%) died and 159 recovered. Overall, 61% of cases were female (n=142), and ages ranged from 1-87 years (median: 30 years). Signs and symptoms included abdominal pain, diarrhea, vomiting, and generalized malaise. Death was preceded by psychomotor agitation and abnormal posturing. The median interval from pombe consumption to symptom onset was 16 hours. Toxic levels of bongkrekic acid (BA) were detected in the suspect pombe but not in the control pombe. Burkholderia gladioli pathovar cocovenenans, the bacteria that produces BA, was detected in the flour used to make the pombe. Conclusions: We report for the first time an outbreak of a highly lethal illness linked to BA, a deadly food-borne toxin in Africa. Given that no previous outbreaks have been recognized outside of Asia, our investigation suggests that BA might be an unrecognized cause of toxic outbreaks globally. |
Neighborhood prices of healthier and unhealthier foods and associations with diet quality: Evidence from the Multi-Ethnic Study of Atherosclerosis
Kern DM , Auchnicloss AH , Stehr MF , Roux AVD , Moore LV , Kanter GP , Robinson LF . Int J Environ Res Public Health 2017 14 (11) It is known that the price of food influences the purchasing and consumption decisions of individuals; however, little work has examined if the price of healthier food relative to unhealthier food in an individual's neighborhood is associated with overall dietary quality while using data from multiple regions in the United States. Cross-sectional person-level data came from The Multi-Ethnic Study of Atherosclerosis (exam 5, 2010-2012 n = 2765); a food frequency questionnaire assessed diet. Supermarket food/beverage prices came from Information Resources Inc. (n = 794 supermarkets). For each individual, the average price of select indicators of healthier foods (vegetables, fruits, dairy) and unhealthier foods (soda, sweets, salty snacks), as well as their ratio, was computed for supermarkets within three miles of the person's residential address. Logistic regression estimated odds ratios of a high-quality diet (top quintile of Healthy Eating Index 2010) associated with healthy-to-unhealthy price ratio, adjusted for individual and neighborhood characteristics. Sensitivity analyses used an instrumental variable (IV) approach. Healthier foods cost nearly twice as much as unhealthier foods per serving on average (mean healthy-to-unhealthy ratio = 1.97 [SD 0.14]). A larger healthy-to-unhealthy price ratio was associated with lower odds of a high-quality diet (OR = 0.76 per SD increase in the ratio, 95% CI = [0.64-0.9]). IV analyses largely confirmed these findings although-as expected with IV adjustment-confidence intervals were wide (OR = 0.82 [0.57-1.19]). Policies to address the large price differences between healthier and unhealthy foods may help improve diet quality in the United States. |
Outcomes among inmates treated for coccidioidomycosis at a correctional institution during a community outbreak, Kern County, California, 2004
Burwell LA , Park BJ , Wannemuehler KA , Kendig N , Pelton J , Chaput E , Jinadu BA , Emery K , Chavez G , Fridkin SK . Clin Infect Dis 2009 49 (11) e113-9 BACKGROUND: Treatment of pulmonary coccidioidomycosis is typically limited to patients with severe disease or those with increased risk of dissemination. In response to an increase of coccidioidomycosis at a correctional institution in an endemic area, physicians initiated an enhanced diagnosis and treatment program. METHODS: Case patients were inmates with laboratory-confirmed coccidioidomycosis during January 1, 2003, through October 31, 2004. We abstracted medical record data, including demographics, IgG complement fixation (CF) titers, treatment, and clinical outcome for initial and follow-up visits. Case patients receiving antifungal treatment were categorized into early (4 weeks from symptom onset) and late treatment groups (>4 weeks after symptom onset). We evaluated clinical outcome, median IgG CF titer, and time to clinical improvement. RESULTS: Eighty-seven persons were diagnosed with coccidioidomycosis; 79 (91%) records were available. Median age was 36 years (range, 21-71 years), 34 (43%) were black, and all were male. Median time from symptom onset to diagnosis was 3 weeks (range, <1-36 weeks). Most (95%) received antifungal therapy; 32 were in the early treatment and 43 were in the late treatment group. Good clinical outcome was equally likely. In both groups, median peak IgG CF titers were 1:64. Titers in patients with early treatment did not decrease more rapidly. Median time to improvement was similar in early and late treatment groups (7 and 6 months, respectively; [Formula: see text]). CONCLUSIONS: Persons incarcerated in endemic areas constitute a susceptible population that should be considered at risk for coccidioidomycosis. Further studies are needed to identify populations that may benefit from early antifungal treatment for pulmonary coccidioidomycosis. |
