If we would need masks, wouldn't we need rubber gloves as well? If I understand correctly, the infection can enter the body through the eyes. (Scenario: Touching a contaminated surface with a bare hand then rubbing your eye?) It wouldn't matter if you were wearing a mask in that situation. I think an individual would be less inclined to rub their eyes while wearing rubber gloves.
(I hope all that makes sense!!!)
Adequate hand washing should suffice. What are you rubbing your eyes for?
