Yeah the ones I'm making aren't to protect the wearer, it's to protect the community from the wearer. Our healthcare providers are being exposed daily and then go home or out into the community, wearing a simple mask can help prevent them from spreading it (they may be asymptomatic)...
Yup. Never know who is walking around like typhoid Mary spreading it without knowing.
Not enough tests for even those with symptoms means protect yourself and those around you.
