Unfortunately, masks aren't going to keep anyone safe, because people don't have a clue how to use them properly, efficiently, or that people just don't have any substantial manners or common sense anymore.
People think wearing a mask is going to save them. WRONG! This is a virus. It is on anything that a contaminated person has touched or breathed on. Wearing a mask isn't going to help if you handle or touch contaminated surfaces or items and then rub your eye or scratch your nose, or wipe your mouth with your fingers.
Medical professionals are even stating that people need to save their money for possible health insurance payments, or drug costs, instead of wasting money on something that doesn't really do any good. If your Dr. deems it necessary for you to wear a mask, then buy some masks. Otherwise, you are just wasting your money.
Medical professionals are also suggesting wearing masks are more detrimental than beneficial, as it takes a respirator mask to filter the coronavirus, not a painters mask, surgical mask, flu mask, or dust mask. And the correct medical/virus respirator masks are usually more expensive than most people can afford.
