Top. Kek. Yeah, you clicked on https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5779801 and guess what. It's a REVIEW ARTICLE. And the very sentence AFTER the one you quoted, Mr. Cherry Picking troll-boi, reads: Findings, however, may not be applicable to influenza and "many studies were suboptimal. None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection."

Which means none of the studies proved masks work. Now make like Kamala with a milk shake.

Aha, I think I found the issue. You think that influenza and Covid are the same thing. They’re not!

You may not know this, but there are many different types of sickness that people can get. Flu and Covid are quite different types!

A study showing that masks don’t work for flu, but are great for SARS, is a pretty good one for why masks would be helpful in this pandemic.
