A recent study by NIH and CDC suggested that COVID can persist in the air and on surfaces for hours, up to even days. Now this was a study performed in a laboratory setting, but we don't yet know how that translates to the real world where things are often very different. These studies are important, we're going to continue doing them, and as we learn more information about what this means to you and your home, we'll keep you informed. Let me remind you though how COVID-19 is transmitted. COVID-19 is transmitted primarily through respiratory droplets. That means particles that come out into the air and then settle relatively quickly. This is different than diseases like measles or tuberculosis that when they get into the air they can float there for a very long time. What can you do to protect yourself against COVID-19 in your home? Using disinfectants. Sure, COVID-19 comes out, it may fall onto a surface, and it could be there for a couple of hours. But the minute you use disinfectant, it's killed. Let's work together to keep ourselves healthy, our families healthy, and our communities healthy.
