Listen to what the experts say and even good masks are little protection from the virus because few people know how to wear/use them to keep from becoming infected.
Lately there has been some evidence that people can spread the virus before they show any symptoms so if they wear a mask they will not spread their germs to others but it will not protect the wearer from others spreading the virus.
BTW you only need one if you can not practice physical distancing of 2 metres or more | |
