Findings from this small study suggested that a qualitative fit test alone is unable to fully assess mask integrity and that at the doses required for sterilization, gamma radiation degrades the filtration efficiency of N95 masks. A set of 3M 8210, Read More

Large gatherings pose a risk for SARS-CoV-2 transmission. High transmission rates have been reported from hospitals, long-term care facilities, family gatherings, and a choir practice. This public health investigation focused on the transmission of SARS-CoV-2 among persons who attended church Read More

Public use of face masks for limiting the spread of the COVID-19 pandemic is controversial, though increasingly recommended. The impact of this intervention on morbidity and mortality is not well understood. This study developed a compartmental model for assessing the Read More

This article discusses therapeutic and prophylactic interventions for SARS-CoV-2 with a focus on vaccine development and its challenges. In brief, the authors believe that, even though vaccines are being rapidly developed, they will likely come too late to affect the Read More

It appears that the same measures to prevent the spread of COVID-19 in Taiwan have also significantly slowed the spread of influenza. These measures work. Taiwan has been at the forefront of infection control measures to prevent the spread of Read More

This study provides evidence that room ventilation, open space, sanitization of protective apparel, and proper use and disinfection of bathrooms can effectively limit the concentration of SARS-CoV-2 RNA in the air.  While we are confident that COVID-19 can be spread Read More

This study found that than half of skilled nursing facility residents with positive COVID-19 tests were asymptomatic at the time of testing and most likely contributed to transmission. Researchers assessed the transmission and adequacy of symptom-based screening to identify infections Read More

This report describes an investigation of coronavirus disease 2019 in residents and staff members from homeless shelters in four U.S. cities between March 27 and April 15, 2020. The authors performed reverse transcription–polymerase chain reaction testing at commercial and public Read More
