What face masks actually do against coronavirus 4.5

Face masks don't make you invincible.

The fight against coronavirus is global. But the guidelines on whether you should wear a face mask as part of that fight are often completely different from place to place. That means that, for a lot of people, whether you wear a face mask when you leave the house is basically up to you.

Here’s where almost every expert agrees: If you have Covid-19, and you leave the house, you should wear a mask. Masks help keep sick people from spreading their germs. Most of the uncertainty around mask use is related to a totally separate question: Whether healthy people should also wear masks to protect themselves from infection.

The truth is that no mask can actually guarantee that you won’t get sick; experts say one of the most dangerous assumptions about face masks is that they basically make you invincible. Masks have to be used correctly to offer any protection at all, and they’re most effective if used alongside other preventative measures like hand-washing and social distancing.

But experts also say that the question of whether healthy people should wear masks matters a lot less when you consider one of Covid-19’s most dangerous characteristics: Because of the disease’s long incubation period, and the high occurrence of infected people who never feel symptoms at all, it’s almost impossible to be completely sure that you don’t already have it. And that means the safest course of action is ultimately for everyone to behave like a sick person; in other words, to wear a mask.

Someone needs to do a survey asking those people who have been hospitalized with the who actually wore a mask and also did they properly wash their hands.

If we assume we're all affected, sheltering in place would work better.

I live in Seattle..I wore mask recently and this lady asked me whether I was sick. I said no, then she followed me around to tell me how ineffective masks are and that I shouldn’t wear it. If she is not wanting to wear it, it’s her choice and I respect that. But don’t judge others for their choices to do anything possible to protect themselves and others around, please.

They say a mask won’t protect you from getting covid-19 BUT will prevent spread if you are sick... wouldn’t that mean that even if sick people wear masks their germs can still escape? if germs can get in then they can come out too.. right?. Im confused.

Unfortunately as a grocery store clerk I actually see people touching their face and their mask all the time, and at least 25% to 50% of those wearing masks are wearing them incorrectly. I wonder where these experts get their data from.
