Outbreaks of coronavirus disease 2019 (COVID-19) have been reported in nursing homes and assisted living facilities; however, the extent of asymptomatic and presymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in this high-risk population remains unclear. ⋯ SNFs are particularly vulnerable to SARS-CoV-2, and residents are at risk of severe outcomes. Attention must be paid to preventing outbreaks in these and other congregate care settings. Widespread testing and infection control are key to help prevent COVID-19 morbidity and mortality in these high-risk populations.

Community-acquired bacterial pneumonia (CABP) remains a significant cause of morbidity and mortality worldwide. Antimicrobial resistance, including in pathogens that cause CABP, continues to spread at an alarming rate. Because of these factors, the development of new antibiotic classes is urgently needed. ⋯ Available in both oral and intravenous formulations, lefamulin has potent in vitro activity against both typical and atypical CABP pathogens. The first pleuromutilin to be used systemically in humans, lefamulin has a unique mechanism of action that inhibits protein synthesis by preventing the binding of tRNA for peptide transfer. This review summarizes the available data on lefamulin, including recent evidence from 2 phase III clinical trials (LEAP 1 and LEAP 2), and discusses its potential role in the treatment of CABP.

Little is known about the natural history of asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. ⋯ Asymptomatic SARS-CoV-2 infection is common and can be detected by analysis of saliva or NTSs. The NTS viral loads fall faster in asymptomatic individuals, but these individuals appear able to transmit the virus to others.

We hypothesized that renin-angiotensin system (RAS) blockers have systemic protective effects beyond the respiratory tract and could reduce the risk of viral infections. ⋯ Hypertensive patients using either ARBs or ACEIs exhibit a lower risk of viral infection than nonusers.

Healthcare workers (HCWs) who serve on the front lines of the coronavirus disease 2019 (COVID-19) pandemic have been at increased risk for infection due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in some settings. Healthcare-acquired infection has been reported in similar epidemics, but there are limited data on the prevalence of COVID-19 among HCWs and their associated clinical outcomes in the United States. ⋯ During the study period, we observed that the prevalence of positive SARS-CoV-2 tests among symptomatic HCWs was comparable to that of symptomatic nonfrontline staff. Reliable and rapid access to testing for employees is essential to preserve the health, safety, and availability of the healthcare workforce during this pandemic and to facilitate the rapid return of SARS-CoV-2-negative employees to work.
