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 masks can protect healthy people from getting Covid-19.

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 is a lot easier to answer 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.

After reading the various comments below I have come to the conclusion that we are all toast.

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 you're sick, you shouldn't leave the house without a mask"...

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.

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.

You could give them a million Masks and they would ask for 2 million. Its like shovling fleas across a barn, only about half of them get there.

Co workers laughed weeks ago when this granny started wearing one. Now it's required. No laughter now.

Question: Should we normalize wearing masks at other times, not just during this pandemic? Say, if you feel like you might have a cough, or in extreme cases the flu, should you then go out with a mask?

It makes you wonder when news reporters interacting with a crowd take off their mask when the reporting is done. Even some of the camera men are not wearing them.

Jason Lee I have lived and worked in Shanghai for over 5 years. Not one of my friends, acquaintances, co workers ect. Wear a mask To protect others. It is worn for protection from the choking pollution and secondarily in case of outbreaks. It is strictly used for personal protection. Your comments are disingenuous at best.
