That’s a reasonable observation. There’re many examples of someone getting exposed then bringing it home to infect the rest of the family. Of course the person who infects the family has to get it somewhere doesn’t he? That’s the best reason to take every precaution when you go out in public.....isn’t it?
Wear all the masks you want if its your turn its your turn. A mask wont save you or me or anyone else.
It’s pretty clear. If you’re in a house with 5 people and one brings it in and infects the other 4 then most of the spread is in the house. Point is that a single person acting irresponsibly can hurt many more.
Do you think going out in public was ever completely safe? Think of the millions of people we could have saved if we banned cars.
That is not how infectious disease spread works. You have some sort of pre Black Plague, Dark Age, Catholic Church philosophy working.
