Here’s a handy checklist for shared bathroom use.

The best defenses against bathroom contagions are a mask, social distancing, limiting the surfaces you touch with your hands and hand hygiene.

Consider larger bathrooms with multiple stalls because they have more air circulation.

If someone exits a bathroom stall or a single bathroom right before you, try waiting at least 60 seconds before entering — especially if the toilet seat lid is up, signifying more plume.
