I don't understand why ppl are obsessed with masks? If you're healthy with no symptoms, you are not supposed to wear it. I see ppl in the streets with masks, touching it every 2 minutes, taking it off to talk on the phone then putting it back and touching their face, eyes, etc. Masks are for sick ppl to not spread it, or for doctors for a short use.
Wash your hands with soap, this will help you.
