Transcript for What you need to know about a fall & winter COVID-19 surge
Let's start with this, we're tracking all of the latest, major developments here and this is what we're getting, the numbers from Johns Hopkins university, now more than 8.6 million cases here at home in the U.S., with more than00 American lives lost in this pandemic. And 83,000 new cases just yesterday according to Johns Hopkins university, which is so alarming, and we're see numbers higher now than we did in the spring. Dr. Fauci is warning about what could be to come winter. What's contributing to this? They're calling this the potential dark winter, not "Game of thrones"-like at all. We have to put some perspective on this. In the spring, people thought the cases were going to go down, they remained high. The background, influenza, they tend to increase in the winter and decline in the summer. So what we were seeing in this country in the summer may have actually been a decline, but we had no reference point. There are viral factors at play, we know at this point, sars-cov-2, they like a cold, dry environment. And then, there are human factors. More people obviously indoors. Closely together. More densely populated. Poor ventilation, and probably the biggest human factor at this point, the majority of the U.S. Population is still naive or susceptible to covid-19. All of this causing one Stanford university microbiologist to say, quote, we're looking at pretty sobering months ahead. What are we supposed to do now? Well, I think as we wait for some type of prevention in vaccines and better therapeutics, we have to control the controllables, which is our behaviors, like ventilation, spacing people out even indoors and the big question mark, you guys, is whether or not we'll see an official recommendation from the CDC that we should start wearing masks indoors to slow this spread. A lot unknown that will be unfolding over the next couple of months. What would you guess? I think there's a good possibility. All right, Dr. Ashton, thank you so much.
