So the doctors on this thread saying that masks can be effective to prevent a person infected spreading it are wrong?
They’re not saying they’re effective. They won’t “prevent” an infected person spreading it, but you know that. As I’ve said countless times, you could wear a helmet 24/7 and it would probably prevent you being seriously injured if you fell, but we don’t do that.
You seem to obsess over certain things. First it was lockdowns, then border closures, then vaccines, now masks. You’re going to need to accept that this is as good as over.
