Let's take a closer look at the considerations public health officials have had to weigh in making their rec- ommendations. Imperfect Protection There is evidence that proper use of medical masks — sup- plemented where appropriate with a respirator and/or face shield — may protect the wearer from contracting COVID-19, which, like influenza and measles, appears to spread prima- rily through respiratory droplets. Unfortunately, medical masks don't provide 100 percent protection, and the protection they do provide depends greatly on correct use. That includes making sure your mask is properly fitted; regularly replacing it (after each use or as often as supplies permit); avoiding touching the mask while wearing it and after removing it; and treating discard- ed masks as hazardous waste. Although most clinicians understand the guidelines for proper mask use, that isn't necessarily true of the general public, and even people who understand the appropriate precautions may not be in a position to follow them outside of a clinical setting. Improperly used medical masks, or nonmedical or impro- vised ones, may provide little meaningful protection for wearers. If you've seen people at the grocery store wearing masks on their chins or lifting their masks to scratch their noses, you can readily understand why! Making Sense of Masks Cutting through the mixed messages MASK MISCONDUCT Masks are most useful for containing respiratory droplets, which can transmit COVID-19 or other viruses. However, a mask can only do that if it fully covers both the wearer's nose AND mouth! Illustration by Jasmin Mora
