This is the only way forward. You must wear a 100% effective mask, 24 x 7, including at home, for eternity. It is the only way to stop viruses. You must be trained to properly size, fit, position, and remove and dispose of your mask – and your clothing – and scrub yourself thoroughly. If you are in a room with virus particles in the air, they cover everything – not just your mask. Once on your hair and clothing, viruses can transfer via your hands to your face.
We don’t need just masks – we need full, disposable hazmat suits. Anything less is unacceptable. And who cares about the environmental costs of daily disposable hazmat suits.
