[*Note from HIFA moderator (Neil PW): How long can the coronavirus stay alive in air? A google search suggests:

'A study done by National Institute of Allergy and Infectious Diseases' Laboratory of Virology in the Division of Intramural Research in Hamilton, Montana helps to answer this question. The researchers used a nebulizer to blow coronaviruses into the air. They found that infectious viruses could remain in the air for up to three hours. The results of the study were published in the New England Journal of Medicine on March 17, 2020.'

I checked this NEJM study, and it is actually a letter to NEJM which appears to indicate viability for *at least* 3 hours.

'SARS-CoV-2 remained viable in aerosols throughout the duration of our experiment (3 hours)'
