Sep 13, 2024, 6:21 PM4 years into this airborne pandemic, I still see people wearing surgical masks in public. There's no good reason for that when actually effective masks are so cheap. It's a huge failure of public health education. The system won't educate us, so we have to educate each other.

Of course symptomatic people should wear N95s without exhalation valves.
