Foulkes D , Kittner A , Korban C , Anderson K , DeJonge PM , Faherty EAG , Kerins JL , Poretsky R , Pierce M , Atwater R , Tabidze I , Pacilli M . Environ Int 2024 190 108749 ![]() ![]() ![]() The Chicago Department of Public Health tested wastewater samples for the presence of Monkeypox Virus (MPXV) from March 13 through June 26, 2023. There were persistent detections prior to reported cases. This indicated the baseline levels of MPXV prevalence might warrant routine monitoring. Detections in areas without corresponding reported clinical cases might highlight areas where cases are being under-reported by traditional surveillance. |

MMWR Morb Mortal Wkly Rep 2024 73 (19) 424-429 Measles, a highly contagious respiratory virus with the potential to cause severe complications, hospitalization, and death, was declared eliminated from the United States in 2000; however, with ongoing global transmission, infections in the United States still occur. On March 7, 2024, the Chicago Department of Public Health (CDPH) confirmed a case of measles in a male aged 1 year residing in a temporary shelter for migrants in Chicago. Given the congregate nature of the setting, high transmissibility of measles, and low measles vaccination coverage among shelter residents, measles virus had the potential to spread rapidly among approximately 2,100 presumed exposed shelter residents. CDPH immediately instituted outbreak investigation and response activities in collaboration with state and local health departments, health care facilities, city agencies, and shelters. On March 8, CDPH implemented active case-finding and coordinated a mass vaccination campaign at the affected shelter (shelter A), including vaccinating 882 residents and verifying previous vaccination for 784 residents over 3 days. These activities resulted in 93% measles vaccination coverage (defined as receipt of ≥1 recorded measles vaccine dose) by March 11. By May 13, a total of 57 confirmed measles cases associated with residing in or having contact with persons from shelter A had been reported. Most cases (41; 72%) were among persons who did not have documentation of measles vaccination and were considered unvaccinated. In addition, 16 cases of measles occurred among persons who had received ≥1 measles vaccine dose ≥21 days before first known exposure. This outbreak underscores the need to ensure high vaccination coverage among communities residing in congregate settings. |
Correlation of wastewater surveillance data with traditional influenza surveillance measures in Cook County, Illinois, October 2022-April 2023
Faherty EAG , Yuce D , Korban C , Bemis K , Kowalski R , Gretsch S , Ramirez E , Poretsky R , Packman A , Leisman KP , Pierce M , Kittner A , Teran R , Pacilli M . Sci Total Environ 2023 912 169551 ![]() ![]() Influenza is a respiratory illness that can result in serious outcomes, particularly among persons who are immunocompromised, aged <5 years or aged >65 years. Traditional influenza surveillance approaches rely upon syndromic surveillance of emergency departments and public health reporting from clinicians and laboratories. Wastewater surveillance infrastructure developed to monitor SARS-CoV-2 is being used for influenza surveillance in the Chicago area. The goal was to evaluate timeliness and correlations between influenza virus detected through wastewater surveillance and traditional influenza surveillance measures to assess utility of wastewater surveillance for influenza at the county level. Specifically, we measured correlations between influenza virus gene copies in wastewater samples and 1) the number of intensive care unit admissions associated with a diagnosis of influenza, 2) the percentage emergency department (ED) visits for influenza-like-illness, and 3) the percentage of ED visits with influenza diagnosis at discharge(2) in Cook County. Influenza concentrations in wastewater were strongly correlated with traditional influenza surveillance measures, particularly for catchment areas serving >100,000 residents. Wastewater indicators lagged traditional influenza surveillance measures by approximately one week when analyzed in cross-correlations. Although wastewater data lagged traditional influenza surveillance measures in this analysis, it can serve as a useful surveillance tool as a complement to syndromic surveillance; it is a form of influenza surveillance that does not rely on healthcare-seeking behavior or reporting by healthcare providers. |
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. |
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. |
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. |
