Transcript for World Health Organization provides new guidance on wearing masks
We're back with today's weekend download making sure we're protecting ourselves in the best ways possible from covid-19. And the world health organization is providing some new guidance on wearing masks. Joining us now is Dr. Todd ellerin, an ABC news medical contributor and infectious disease physician. Great to see you. Thanks for joining us. There are some areas still seeing a rise in covid cases and even places seeing decreases. We want to make sure we're diligent because we want to keep it that way. Walk us through the new guidance specifically on the masks. Yes, good morning, whit. So basically a little background. So within the past week, "The lancet" came out with a study that was funded by the W.H.O. And it looked at over 170 different studies from around the world, over 25,000 patient interactions and what it showed was that masks, eye protection and physical distancing decreased the risk of covid transmission. So based on this W.H.O. Just recently on Friday changed its guidance and is now recommending that everyone go out with masks, especially if you're within six feet of someone and there is a potential for covid transmission. Now, they also recommended how to use masks safely. And hand hygiene is very important for that. You want to make sure you wash your hands so you're not contaminating your mask when you take it on or take it off. And so that's extremely important. Now, Mr. Tedros, the head of W.H.O., the director general, said masks alone are not enough. You need to consider the other infection control bundles like hand hygiene and like physical distancing.

You want to keep that pandemic distance, three feet is good but six feet or more is better especially if you have someone with chronic conditions or elderly. One other thing I wanted to ask you about too, we understand there is growing concern from the CDC about how people are using disinfectants and cleaning their home, even reports of people gargling with things like bleach. What is some of the new information and guidance we're getting? Okay, so environmental hygiene is really important but some of these chemicals can be dangerous. So a couple of tips. The first one, you don't want to -- you don't want to clean food with bleach, okay. Secondly, you don't want any of the chemicals touching your skin. You don't want to inhale or ingest these disinfectants and very importantly you don't want to mix bleach with something like vinegar because that can create a chlorine gas. So you're sort of inviting chemical warfare on yourself. And lastly you want to keep these products away from children and remember to wear gloves whenever you're cleaning with these disinfectant. Sadly we've seen reports of people misusing these. Dr. Ellerin, thanks. Appreciate it. Talk to you soon. Be back in just a bit with
