Small droplet aerosols in poorly ventilated spaces and SARS-CoV-2 transmission - The Lancet Respiratory Medicine: Globally, health-care authorities are searching for effective measures to prevent
community transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Although data on factors related to this transmission are scarce, the spread of SARS-CoV-2
is thought to mostly be via the transmission of respiratory droplets coming from infected
individuals.1 Small droplets, from submicron to approximately 10 μm diameter, produced
during speech and coughing, have been shown to contain viral particles,2 which can
remain viable and infectious in aerosols for 3 h.
