> Horwitz believes that mask-wearing may be helping by reducing the initial dose of virus a person receives, thereby lessening the overall severity of illness for many patients. Now if only we could drill this lesson into everyone's head.
Except this is happening in countries and states with no mask wearing. So your null hypothesis is shot.
Full disclosure: An alternative explanation here in Norway seems to be that the second wave mostly hits younger people.
Edit: there's a dead comment saying "citation needed".
As for the "hardly a mask to be seen" that is my eyewitness account based on what I see in shops and gas stations I visit as well as reading and watching the news.
