- giarc 6y agoI wouldn't put a ton of weigh to the recent reports of 300 physicians asking the WHO to categorize it as an airborne virus. If it were truly an airborne virus it wouldn't be a very good one. The main source of transmission is close contact with positive patients. If it were airborne we would see a ton more cases (or atleast a ton more unknown source cases). For example, in my province, Alberta, we have 8300 confirmed cases. Only 800 or so are from unknown sources, all the other cases have known links to previous cases [1]. If this were airborne, you would expect many more unknown cases since people would pick it up in grocery stores etc and we wouldn't be able to track it back to the known case. 1. alberta.ca/covid-19-alberta-data.aspx?utm_source=google&utm_medium=sem&utm_campaign=Covid19&utm_term=data&utm_content=v1&gclid=Cj0KCQjwupD4BRD4ARIsABJMmZ8cO5v1TFH7D0uHfjhcZ9aNdMhvWcOdJLqY5_hude3dLqrE1V_HgToaAi_KEALw_wcB Back to your question though, if it were airborne, vapourize products or UVC would work against it but you would have to disinfect after a positive person were present. Given air currents, and air exchange rates in most buildings, a positive person wouldn't leave behind enough of a viral load to affect someone that far past their presence.
