ABSTRACT

SARS-CoV-2 seroprevalence was low (<1%) in this large population of healthcare workers (HCWs) across the state of Tennessee (n=11,787) in May-June 2020. Among those with PCR results, 81.5% of PCR and antibody test results were concordant. SARS-CoV-2 seroprevalence was higher among HCWs working in high-community-transmission regions and among younger workers. IMPORTANCE: These results may be seen as a baseline assessment of SARS-CoV-2 seroprevalence among HCWs in the American South during a period of growth, but not yet saturation, of infections among susceptible populations. In fact, this period of May-June 2020 was marked by the extension of renewed and sustained community-wide transmission after mandatory quarantine periods expired in several more populous regions of Tennessee. Where community transmission remains low, HCWs may still be able to effectively mitigate SARS-CoV-2 transmission, preserving resources for populations at high risk of severe disease, and these sorts of data help highlight such strategies.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has greatly impacted school operations. To better understand the role of schools in COVID-19 transmission, we evaluated infections at two independent schools in Nashville, TN during the 2020-2021 school year. METHODS: The cumulative incidence of COVID-19 within each school, age group, and exposure setting were estimated and compared to local incidence. Primary attack rates were estimated among students quarantined for in-school close contact. RESULTS: Among 1401 students who attended school during the study period, 98 cases of COVID-19 were reported, corresponding to cumulative incidence of 7.0% (95% confidence interval (CI): 5.7-8.5). Most cases were linked to household (58%) or community (31%) transmission, with few linked to in-school transmission (11%). Overall, 619 students were quarantined, corresponding to >5000 person-days of missed school, among whom only 5 tested positive for SARS-CoV-2 during quarantine (primary attack rate: 0.8%, 95% CI: 0.3, 1.9). Weekly case rates at school were not correlated with community transmission. CONCLUSION: These results suggest that transmission of COVID-19 in schools is minimal when strict mitigation measures are used, even during periods of extensive community transmission. Strict quarantine of contacts may lead to unnecessary missed school days with minimal benefit to in-school transmission.

ABSTRACT

Background: The effects of the COVID-19 pandemic on people living with HIV (PWH) are unknown. Beyond SARS-CoV-2 co-infection, the pandemic may have devastating consequences for HIV care delivery. Understanding these is crucial as reduced antiretroviral therapy (ART) availability alone could lead to ≥500,000 AIDS-related deaths in 2020-2021. With Latin America now a focal point in the pandemic, we sought to describe the impact of COVID-19 on HIV care at Latin American clinical sites. Methods: Caribbean, Central and South America network for HIV epidemiology (CCASAnet) and additional Brazilian HIV care sites in Argentina, Brazil, Chile, Haiti, Honduras, Mexico, and Peru were included. An electronic survey of COVID-19 effects on HIV clinic operations was administered in Spanish or English via phone and email, April 28-June 2, 2020. We also compared national COVID-19 case, mortality, and policy data from public sources. Results: Brazil's and Mexico's epidemics appear most pronounced, with >10,000 confirmed COVID-19-related deaths (Figure 1);countries implemented “social distancing” policies at different times after initial cases, with Haiti earliest and Mexico latest (Figure 2). Nearly all 13 sites reported decreased hours and providers for HIV care. Twelve of 13 reported increased use of telehealth, suspension/postponements of routine HIV appointments, and/or suspension of HIV research. Eleven of 13 reported initiation of new COVID-19 research but suspension of community HIV testing, and nearly half provided additional ART supplies. Nearly 70% reported impacts on HIV viral load testing and nearly 40% reported personal protective equipment stock-outs (Table). All 13 sites experienced changes in resources/services in tandem with national policies;there was wide variation, however, in the number of economic and health supports implemented thus far (e.g., quarantines, tax deferrals, interest rate reductions, etc.), from 172 COVID-19-related policies in Brazil to only 30 in Mexico Conclusion: The COVID-19 pandemic has already had a substantial effect on daily operations of HIV clinics in Latin America. The downstream effects of these impacts on HIV outcomes in Latin America will need to be further studied. (Table Presented).
