Cdc covid 19 masks2/29/2024 ![]() That's also where you'll find the latest updates on COVID-19.Ĭheck the CDC website for additional updates on COVID-19. The CDC has more information on cloth masks, including a video on how to make your own face covering. You don't need to go to any extreme lengths. Just washing with soap and water in your laundry machine is quite satisfactory. And then that mask needs to be washed before it would be used again. You take it off through however you're holding it on your head. As medical professionals, we're taught how to put a mask on and how to take a mask off, but this would be unfamiliar to the public. The second thing is you do yourself no favor if you wear a mask and then touch the mask, either to adjust it or take it off in the wrong way. So that's one thing, it would need to be changed. Once a mask gets wet, maybe from our exhalation, it really begins to decrement in effectiveness in filtering any sort of respiratory particulate matter. What are the potential dangers in terms of using a mask?Ī. So there are some materials that appear to be better than others in the few studies that have been done. For example, high-quality, woven tee shirts tend to be better than for example, scarves. Cotton towels that are thicker with tight weaves tend to be better. There have been some studies looking at types of fabric. That would be detrimental to us as a society, health care providers and patients who are sick with the disease need those masks.Ī. We don't want the public to think that the recommendation is for medical masking. So the coronavirus is about 0.12 microns in diameter and N95 (masks) protect down to 0.1 microns, with 95% efficiency, which is where it gets its name. ![]() The idea behind an N95 mask is it has a filtering ability down to, and actually below, the size of SARS-CoV-2, the virus that causes COVID-19. What's the difference between cloth masks and medical masks, such as an N95 mask?Ī. The other side of the coin, if you will, is protecting those who are not infected from becoming infected by breathing in air contaminated with virus or respiratory particulate matter. So in that case, we're preventing me from exhaling the virus or respiratory particulate matter out onto the public and into the air where others might get infected. It's apparent that you can transmit the virus when you are asymptomatic or presymptomatic. It's not like I'm sneezing and coughing, and have a fever. If I had COVID-19, I might not even know it. They are not only a way of decreasing breathing in the virus, primarily through large respiratory droplets, but also a behavioral reminder that there's a pandemic and life is not the same right now ― and a reminder not to put our hands in our eyes nose or mouth until we've washed our hands. The reason to do this, even though they're not quite the same efficacy as medical masks, is that they do have some level of efficacy. Why is the CDC recommending that people wear cloth masks in public?Ī. Gregory Poland are in the downloads at the end of the post.
