Noted: The CDC recommends the public wear cloth masks and not use masks meant for health professionals, including N95 masks. Given that you have “significant underlying conditions,” it’s important that you keep yourself safe and consult your doctor on how best to do that.
It’s safer to avoid public restrooms. If you must use one, be sure you have your mask on when you are inside. If you are not the only occupant, keep six or more feet from others. Avoid touching surfaces including doors, faucet handles, pump soap, etc. If you can wash your hands safely and properly inside the restroom, it’s still a good idea to use alcohol rub to disinfect your hands once you get outside the bathroom. Avoid touching your face unless your hands are clean.
