White House Press Briefing

Dr. WILLIAM BRYAN, HOMELAND SECURITY UNDER SECRETARY FOR SCIENCE AND TECHNOLOGY: 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 bring it on and leaving 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.
This is not the end of our work. As we continue to characterize this virus and integrate our findings into practical applications to mitigate exposure and transmission, I would like to thank the President -- thank the Vice President for their ongoing support and leadership to the department and for their work in addressing this pandemic. I would also like to thank the scientists not only in the S&T and the INBAT, but to the larger scientific and R&D community. Thank you very much.
PRESIDENT DONALD TRUMP: (inaudible) -- a question that some of you are probably thinking if you're totally into that world, which I find to be very interesting. So supposing we hit the body with a tremendous -- whether it's ultraviolent or just powerful light -- and I think you said that hasn't been checked, but you're going to test it.
And then I said, "Supposing you brought the light inside the body?" which you could do either through the skin or in some other way, and I think you said you're going to test that, too. Sounds interesting.
And then I see the disinfectant where it knocks it out in a minute -- one minute. And is there a way we can do something like that by injection inside or almost a cleaning? Because you see it gets in the lungs and it does a tremendous number on the lungs, so it would be interesting to check that, so that -- you're going to have to use medical doctors, but it sounds interesting to me.
