Highlights:
July 28, 2020 - a prison guard had 22 brief encounters, for a total of 17 minutes with 6 prisoners.
July 29, 2020 - all 6 tested positive
The guard had 2 other contacts - those people did not test positive.
All interactions were on video.
The guard was in a microfiber cloth mask and goggles the entire time.
So, ocular infection in this case was eliminated.
Anyway - was he infected from repeated exposures?
Possibly, but not probably.
No, he was probably infected during only one of those interactions.
But is that the end of the story?
It shouldn't be.
Where, oh where, can we possibly find someone who could help us see if there's a better definition of close contact?

As I have, & will continue to point out, @nirav_uscdc, they continue to ensure dairy workers are NOT told to wear N95s. Or PAPR as indicated would be more comfortable by @RanuDhillon @sri_srikrishna.
But worn here in their lab. By them.
Aerosols, 3-5 microns, were nebulized into the cows nostrils.
Correction to the study...SOME of those that size will deposit into the Lower Respiratory Tract. Not all. Some will deposit into the Upper Respiratory Tract.
