Transcript for Keeping the family safe during COVID-19
Dr. Ashton, let's get to viewers' questions. Can coronavirus stay in my hair or in my beard? Theoretically, it's possible. They haven't studied that in a lab environment. Here's the important thing with you would hope and one would think you would be washing your hair and washing your beard at some point. You would think. That kills the virus. We have to emphasize that fomite transmission, that surface contact to this virus, is really not the major root of spread. We have to inhale it. I wouldn't worry about the hair anywhere on the body. That's good to know. You're talking about washing your hair. Washing your hands. Our next viewer asks how does soap kill coronavirus? This is a great bio chemistry question. Has to do with the lipid layer that coats the virus. Soap has a fatty layer. When the two get together, literally that lipid surrounding the virus gets disintegrated. The virus collapses. Look at T.J. Back in the lab. You're a biochemist. We had to learn these things. I've long since forgotten. The other important thing with hand washing and soap is the mechanical agitation. You need the 20 seconds. You also need the vigorous motion. If I'm in a pinch and can't wash my hands can I use alcohol as hand sanitizer? Yes and no. When you get an injection, a flu vaccine, we use alcohol wipes. So it can disinfect the skin. When you talk about pouring alcohol all over your hands, that's not good for your skin. Potentially absorption and toxicity issues. You can get to a sink generally in a few minutes. Don't touch your face. We say that over and over. Again, we're looking for hand sanitizers that have at least 60% alcohol in them. This was one of my favorite question and answer sessions. Look at T.J. That was great. I like it. Doc, thank you. You can submit your great questions to Dr. Jen on her Instagram @drjashton.
