Transcript for Why isn’t there a vaccine for the common cold?
Give you chills, doesn't it? Dr. Jen Ashton here with answers to your medical questions now around coronavirus and its spread. The first one, did we see any outbreaks as the result of the widespread protests throughout the country this summer? Short answer, Amy, is really we didn't. Obviously, the main cities that had high numbers of social demonstrations were on the lookout for this. New York City. Los Angeles. That's right. They really didn't see a bump. So theories about that, many people did have masks on, but it was outdoors. We said it before, it bears repeating, all evidence points to that being a much safer environment. It helps in terms of reducing the risk that you could get exposed to the virus. Okay, next question, are eye drops or nasal spray effective to flush the eyes and nostrils of the virus after being out in public areas? Short answer is no. But I like the question. Basically, our little hairs in our nose and mucous are there for a reason, they are forming a barrier, a physical barrier against particles, and obviously you don't want to irritate those mucous membranes with too much. People are studying this, under under research, it not a recommendation at this point. Okay, next question, would it help to spray masks with a water repellant solution to keep the virus droplets out? Like our leather and shoes, is that what they're talking about? Again, it's an interesting concept, but the answer is no. And I'll tell you why, a couple of reasons, number one, the mask integrity depends on fit and fabric. If that fabric gets wet or chemically treated with a variety of substances, it can actually weaken or lower the integrity as a barrier. Then you may be breathing in something that's toxic. You don't want those masks, whatever kind you're wearing, to get wet. That's when they really lose their effectiveness. So, right now, no. Again, it's under r&d. A great barrier if it existed. Okay, all right, that's very interesting information. Dr. Jen, thank you as always. You can submit questions to Dr. Jen on her Instagram @drjashton.
