Oh bull chit...
They eradicated flu last year
No kidding. By wearing a mask, you kill all knows pathogens, viruses, bacteria, radiological and chemical hazards to humans, and they DID say they eradicated influenza (more or less) last year because the Wuhan virus made everyone immune to it (to paraphrase some academic / pop culture bullshit).
This is just silly to us smart folks, but the commies just love it all.
