I found the article (2018) below about disinfecting after H1N1. I do not know the effectiveness of far-UVC light killing COVID-19 although the article includes bacteria and viruses. I did a quick search on the cdc.gov site and did not see anything connecting COVID-19 and UVC or far-UVC disinfection. https://www.merckmanuals.com/home/news/external/2018/02/12/17/15/shining-a-d... https://www.amazon.com/Ultraviolet-Disinfection-Lamp-Professional-Rechargeable/dp/B085379YJL/ref=sr_1_1?dchild=1&keywords=far+UVC+wand&qid=1584032832&sr=8-1 The idea is thanks to my partner who studied emergency response in the army!
