If I wear two masks in public instead of one. Will it help reduce the chance of getting coronavirus?

It really depends on what type of mask you wear. I recommend trying a candle test to see if you're wearing a good mask or not. (Wear your mask, hold a candle close to your face, and blow. If the candle flickers, it's not a good mask.) If you don't have a good mask, then you should definitely wear two, but if it works ok, it will only make a little difference.
