how are masks effective against coronavirus? pls give an essay

Answer 1

Answer:

Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time.

• Make sure it covers both your nose, mouth and chin.

• When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask, or dispose of a medical mask in a trash bin.

• Don’t use masks with valves.
