Pointing to charts with data from experiments on the COVID-19 virus, Bryan said the virus half life plunges "drastically" with exposure to higher temperatures and even minimal exposure to humidity. Bryan said the DHS bio containment lab is the only one in America that has the capability to do the kind of testing that has led to the research on the virus' UV and temperature tolerance.

Bryan explained the mechanics of the COVID-19 temperature tolerance experiment in simple terms. He said the virus was first locked into a 5 gallon bucket and suspended in the air inside. "We're able to take a particle of a virus and suspend it in the air inside of this drum and hit it with various temperatures, various humidity levels, multiple different kinds of environmental conditions to include sunlight. And we're able to measure the decay of that virus while it's suspended in the air. This is how we do our aerosol testing." "While there are many unknown links in the COVID-19 transmission chain, we believe these trends can support practical decision making to lower the risks associated with the virus," Bryan said.

The DHS team has also tested the effect of bleach and isopropyl alcohol on the virus, "specifically in saliva and 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."
