So a mask and isolation prevent flu but not COVID.Proper isolation would prevent both (obviously), unless some idiot breaches regulations/recommendations and introduces infection into shared living spaces.
And the chinstraps, I mean masks some use, do not prevent anything. But that's your opinion and that's good.
When did I say masks prevent getting infected? It’s like you people live in a fantasy land, just making up other people’s opinions in your own minds.
