3. Keys

As we already mentioned, the coronavirus can live for days on certain surfaces such as metal. And, the number one metal object we use every single day is our keys. They are “something we often use, don’t sanitize, and we may inadvertently touch our faces after usage,” says Candice Williams, MD, a board-certified anesthesiologist and pain management specialist based in Los Angeles.

We all use our keys when we return home, and, perhaps we use them at a time when it’s been a while since we last washed our hands. And even if we do wash our hands before we leave the house, keys are one of the last things we grab before we go, picking up all those germs we’ve left on them yesterday.
