Indoor CoVid Transmission Predominately Via Surfaces Vidcast:  https://youtu.be/RzSesPsN54o   If you are in a room with a CoVid19 carrier, asymptomatic and unaware of their infection, you are more likely to contract the virus from surfaces than from the air.  Israeli biomathematicians draw this conclusion from theie mathematical models of viral transmission through the air versus surface-hand-face transfer.   Using real life data, the investigators estimate that 60-80% of virus is transmitted via direct contact, 20-40% is transmitted via indirect contact with contaminated surfaces, and less than 1% via the air.   This data predicts that the combination of frequent hand washing, avoiding direct physical contact, and periodic surface disinfection will reduce the risk of person-to-person viral transmission by 85%.   https://www.medrxiv.org/content/10.1101/2020.05.12.20099085v1.full.pdf   #covid #pandemic #transmission #droplets #aerosols #fomites
