This is a nice and clear (and short) editorial by Joseph Allen and Linsey Marr; “Recognizing and controlling airborne transmission of SARS‐CoV‐2 in indoor environments“. Basically they summarize the evidence for airborne transmission and suggest some mitigation strategies. Definitely worth a read. Abstract below:
Sharing indoor space has been confirmed as a major risk factor in transmission of SARS‐CoV‐2. A study of over 7000 cases found that all outbreaks involving three or more people occurred indoors.1 Thus, identifying the dominant modes of transmission is an urgent public health priority so that appropriate control strategies can be selected and deployed. Here, we present three lines of evidence supporting the potential for airborne transmission and recommend steps to mitigate the risk in indoor environments.
