Let's imagine you are a medical professional at a drive-through Corona testing facility, like the ones they just announced will be in Walmart parking lots across the country. You get fully suited up head to toe including N95 mask, googles, etc. You take a sample from ONE person, that person leaves, you now take off every piece of gear and put on a new set. You can sanitize your goggles, but the N95 mask has to be disposed of. Let's imagine you're a nurse at an ICU. You have two patients, as is customary for most ICUs. Every 15-20 mins you have to suit up, check your patient, unsuit, resuit, check other patient. Every 15-20 mins you are using two N95 masks. You do this 3-4 times per hour 24 hours a day. And you're just the nurse. You also have doctors, respiratory therapists, techs, and other people coming in and out of the room, all of whom will be disposing of an N95 mask.
