Vermund SH, Pitzer VE. Asymptomatic transmission and the infection fatality risk for COVID-19: Implications for school reopening [published online ahead of print, 2020 Jun 25]. Clin Infect Dis. 2020;ciaa855. doi:10.1093/cid/ciaa855
Asymptomatic infection occurs for numerous respiratory viral diseases, including influenza and COVID-19. We seek to clarify confusion in three areas: age-specific risks of transmission and/or disease; various definitions for the COVID-19 “mortality rate”, each useful for specific purposes; and implications for student return strategies from pre-school through university settings.
