SARS-CoV-2 Aerosol Exhaled by Experimentally Infected Cynomolgus Monkeys

Emerg Infect Dis. 2021 Jul;27(7):1979-1981. doi: 10.3201/eid2707.203948.

Abstract

We analyzed size of severe acute respiratory coronavirus 2 (SARS-CoV-2) aerosol particles shed by experimentally infected cynomolgus monkeys. Most exhaled particles were small, and virus was mainly released early during infection. By postinfection day 6, no virus was detected in breath, but air in the isolator contained large quantities of aerosolized virus.

Keywords: 2019 novel coronavirus disease; COVID-19; SARS-CoV-2; aerosol transmission; breath; coronavirus disease; cynomolgus monkeys; respiratory infections; severe acute respiratory syndrome coronavirus 2; size distribution; viruses; zoonoses.
