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.)

Here is the testimony of industrial hygeinist @pettypodcast1 last week in New Hampshire presenting the consensus of the field that (unlike medical doctors) has subject matter expertise on abatement of airborne contaminants.

"Physicians who’ve taken time to analyze the high-quality studies on masks know this."

Physicists knew this back in May 2020. We were munching on popcorn watching the show put on by the CDC when we weren't throwing food at the screen.

Physicists think about things like droplets evaporating, the rate of evaporation, masks wicking droplets, etc. It's kind of obvious to physicists that the CDC's droplet story was silly.
