We're also testing disinfectants readily available. We've tested bleach, we've tested isopropyl alcohol on the virus, specifically in saliva or in respiratory fluids. And I can tell you that bleach will kill the virus in five minutes; isopropyl alcohol will kill the virus in 30 seconds, and that's with no manipulation, no rubbing--just spraying it on and letting it go. You rub it and it goes away even faster. We're also looking at other disinfectants, specifically looking at the COVID-19 virus in saliva.
