Masks can’t reduce Covid infection rates or transmission of any virus: Petty

Viruses travel in aerosols that stay suspended in air up to 50 days

Industrial hygienist Stephen Petty gave excellent testimony in the New Hampshire Senate on how masks don’t block aerosols and can’t reduce viral infection rates.

(His PDF handout is here.)

Physicians who’ve taken time to analyze the high-quality studies on masks know this. (See here, here, here, and here.)

Unfortunately, many doctors who haven’t had time to read the studies rely on government officials or health administrators issuing scientifically unsupportable masking mandates.

It appears you’re being forced to wear masks for weird and possibly dangerous reasons. (See also here, here, here, and here.)
