Just so you don't have to exercise your brain cells too much this is one of many studies occurring at this time not so much to prove the point but to prove how long they stay in the air and how long they are active
The National Academy of Sciences (NAS) has given a boost to an unsettling idea: that the novel coronavirus can spread through the air—not just via the large droplets emitted in a cough or sneeze. Though current studies aren’t conclusive, “the results of available studies are consistent with aerosolization of virus from normal breathing,” Harvey Fineberg, who heads a standing committee on Emerging Infectious Diseases and 21st Century Health Threats, wrote in a 1 April letter to Kelvin Droegemeier, head of the White House Office of Science and Technology Policy.
Also if you have any friends who are in the Defense Forces ask them what instructions they have been given regarding full protective cover and total de-lousing at the end of their shifts due to aerosol danger
