Topic:

  • Barrett et al report on the prevalence of SARS-CoV-2 infection in previously undiagnosed U.S. healthcare workers in the early phase of the U.S. COVID-19 epidemic. They report a prevalence of 7.3 and 0.4% SARS-CoV-2 infection in healthcare and non-healthcare workers, respectively. They attribute the 7.0% greater absolute risk to high levels of close patient contact by healthcare workers and call for additional strategies to protect these critical frontline workers.
