RESUMO
There are limited real-world data on the effectiveness of tixagevimab-cilgavimab as pre-exposure prophylaxis of COVID-19. We describe lessons learned when coordinating data collection and identifying breakthrough SARS-CoV-2 infections among patients across indications and institutions in a major US city. The Chicago Department of Public Health requested patient-level tixagevimab-cilgavimab administration data from all prescribing providers in Chicago, for treatments December 8, 2021 through June 30, 2022. Records were matched to COVID-19 vaccinations and laboratory-confirmed SARS-CoV-2 infections through December 31, 2022. Due to difficulty collecting data from all providers, targeted follow-up was conducted to improve completeness on key variables (demographics, vaccination status, clinical indication for prophylaxis). Over half of reported tixagevimab-cilgavimab administrations were to patients residing outside Chicago. Five hundred forty-four Chicago residents who received at least one dose of tixagevimab-cilgavimab were included in this analysis. Most were age 50 years or older (72%), Black non-Latinx (33%) or White non-Latinx (29%), and fully vaccinated (80%). Seventy-five patients (14%) had laboratory-confirmed COVID-19. Patients with and without breakthrough infections were demographically similar. Clinical indication was missing for >95% of cases, improved to 64% after follow-up; the most frequently specified was hematologic malignancy (10%). Severe outcomes were uncommon: 16% had documented COVID-19-related hospitalizations, one death was identified. Tixagevimab-cilgavimab recipients in Chicago had a lower rate of severe SARS-CoV-2 infection than reported among other untreated high-risk patients, including during predominance of non-neutralizing variants. Improving stakeholder collaboration is essential for generation of real-world effectiveness data, informing pandemic preparedness and optimizing use of medical countermeasures.

BACKGROUND: In 2012, Chicago Public Schools and the Chicago Department of Public Health partnered together to create the Chicago School-Based Vision Program (CSBVP). This ongoing, city-wide program provides school-based vision services (eye examinations, eyeglasses provision, and eye care referrals) to students with limited access. METHODS: Descriptive analysis of the program operations from 2012 to 2020, including number of students served and exam findings during 2017-2020, as well as lessons learned and recommendations for reproducing the successes of the CSBVP in other contexts. RESULTS: During its first 8 years, the CSBVP provided eye examinations to over 350,000 students. During the years 2017-2020, this included 126,238 eye exams and provision of eyeglasses to 73,751 students. CONCLUSIONS: The CSBVP is built upon strong community and school relationships. The program offers vision services, equitably, to all students across the district. The lessons learned through the implementation of the CSBVP may provide guidance for future district-wide vision programs.

OBJECTIVES: We describe clinical characteristics, pregnancy, and infant outcomes in pregnant people with laboratory-confirmed SARS-CoV-2 infection by trimester of infection. STUDY DESIGN: We analyzed data from the Surveillance for Emerging Threats to Mothers and Babies Network and included people with infection in 2020, with known timing of infection and pregnancy outcome. Outcomes are described by trimester of infection. Pregnancy outcomes included live birth and pregnancy loss (<20 weeks and ≥20 weeks gestation). Infant outcomes included preterm birth (<37 weeks gestation), small for gestational age, birth defects, and neonatal intensive care unit admission. Adjusted prevalence ratios (aPR) were calculated for pregnancy and selected infant outcomes by trimester of infection, controlling for demographics. RESULTS: Of 35,200 people included in this analysis, 50.8% of pregnant people had infection in the third trimester, 30.8% in the second, and 18.3% in the first. Third trimester infection was associated with a higher frequency of preterm birth compared to first or second trimester infection combined (17.8% vs. 11.8%; aPR 1.44 95% CI: 1.35-1.54). Prevalence of birth defects was 553.4/10,000 live births, with no difference by trimester of infection. CONCLUSIONS: There were no signals for increased birth defects among infants in this population relative to national baseline estimates, regardless of timing of infection. However, the prevalence of preterm birth in people with SARS-CoV-2 infection in pregnancy in our analysis was higher relative to national baseline data (10.0-10.2%), particularly among people with third trimester infection. Consequences of COVID-19 during pregnancy support recommended COVID-19 prevention strategies, including vaccination.

We aimed to describe coronavirus disease 2019 (COVID-19) deaths among first responders early in the COVID-19 pandemic. We used media reports to gather timely information about COVID-19-related deaths among first responders during March 30-April 30, 2020, and evaluated the sensitivity of media scanning compared with traditional surveillance. We abstracted information about demographic characteristics, occupation, underlying conditions, and exposure source. Twelve of 19 US public health jurisdictions with data on reported deaths provided verification, and 7 jurisdictions reported whether additional deaths had occurred; we calculated the sensitivity of media scanning among these 7 jurisdictions. We identified 97 COVID-19-related first-responder deaths during the study period through media and jurisdiction reports. Participating jurisdictions reported 5 deaths not reported by the media. Sixty-six decedents worked in law enforcement, and 31 decedents worked in fire/emergency medical services. Media reports rarely noted underlying conditions. The media scan sensitivity was 88% (95% CI, 73%-96%) in the subset of 7 jurisdictions. Media reports demonstrated high sensitivity in documenting COVID-19-related deaths among first responders; however, information on risk factors was scarce. Routine collection of data on industry and occupation could improve understanding of COVID-19 morbidity and mortality among all workers.

Reopening in-person education in public schools during the coronavirus 2019 (COVID-19) pandemic requires careful risk-benefit analysis, with no current established metrics. Equity concerns in urban public schools such as decreased enrollment among largely Black and Latinx prekindergarten and special needs public school students already disproportionately impacted by the pandemic itself have added urgency to Chicago Department of Public Health's analysis of COVID-19 transmission. Close tracking within a large school system revealed a lower attack rate for students and staff participating in in-person learning than for the community overall. By combining local data from a large urban private school system with national and international data on maintaining in-person learning during COVID-19 surges, Chicago believes in-person public education poses a low risk of transmission when the operational burden imposed by the second wave has subsided.

BACKGROUND: People experiencing homelessness are at increased risk of coronavirus disease 2019 (COVID-19), but little is known about specific risk factors for infection within homeless shelters. METHODS: We performed widespread severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction testing and collected risk factor information at all homeless shelters in Chicago with at least 1 reported case of COVID-19 (n = 21). Multivariable, mixed-effects log-binomial models were built to estimate adjusted prevalence ratios (aPRs) for SARS-CoV-2 infection for both individual- and facility-level risk factors. RESULTS: During March 1 to May 1, 2020, 1717 shelter residents and staff were tested for SARS-CoV-2; 472 (27%) persons tested positive. Prevalence of infection was higher for residents (431 of 1435, 30%) than for staff (41 of 282, 15%) (prevalence ratio = 2.52; 95% confidence interval [CI], 1.78-3.58). The majority of residents with SARS-CoV-2 infection (293 of 406 with available information about symptoms, 72%) reported no symptoms at the time of specimen collection or within the following 2 weeks. Among residents, sharing a room with a large number of people was associated with increased likelihood of infection (aPR for sharing with >20 people compared with single rooms = 1.76; 95% CI, 1.11-2.80), and current smoking was associated with reduced likelihood of infection (aPR = 0.71; 95% CI, 0.60-0.85). At the facility level, a higher proportion of residents leaving and returning each day was associated with increased prevalence (aPR = 1.08; 95% CI, 1.01-1.16), whereas an increase in the number of private bathrooms was associated with reduced prevalence (aPR for 1 additional private bathroom per 100 people = 0.92; 95% CI, 0.87-0.98). CONCLUSIONS: We identified a high prevalence of SARS-CoV-2 infections in homeless shelters. Reducing the number of residents sharing dormitories might reduce the likelihood of SARS-CoV-2 infection. When community transmission is high, limiting movement of persons experiencing homelessness into and out of shelters might also be beneficial.
