If you are like in close contact with someone infected, a mask cuts the chance of the disease being passed on. According to the GuardianUk masks will probably make little difference if you’re just walking around town or taking a bus so there is no need to bulk-buy a huge supply.

You need to wear a mask regardless because you don’t know who is infected. Heck, some infected people don’t even know they’re infected.

I follow San Bernardino county / California regulations and it falls for a mask whenever you leave your house or pay a $2,000 (N800,000) fine. It’s that serious.
