As a certified armchair epidemiologist, I think what matters is at what distance there is a significant risk of transmission. The mere existence of positive samples doesn't mean shit.

And where did you get your certification? TNCR?

I would be amazed if their shoes weren’t getting covered. Guess I should stop licking nurses shoes.

As far as the 4 meters, I can see that being possible, but not the norm. Just like on the cruise ship where they found the virus living on surfaces two weeks later. That’s the exception, not the typical results. I think Fauci mentioned that you will always find extremes as to what is possible, but you live, plan, and work towards the 99%...

Assuming that gravity is pulling the virus down during it's 12 feet of flight, between 6 and 12 feet it is more likely the pants that need protection.

We'll need aprons to go with the masks.

It's not. Read the Dutch and French study on that. Outdoors it dissipates better, but indoors most of it stays in the air for 3 minutes.

BEVERLY — More people are getting out and going for walks as a means of exercise during the coronavirus pandemic. However, that means foot traffic is increasing on Beverly’s sidewalks, an issue that is being actively addressed.

The Beverly Board of Health has ordered that all foot traffic on sidewalks be in one direction; pedestrians are advised to walk facing oncoming traffic at all times.

“If you go out walking, please walk on the left side of the street facing traffic, otherwise you’ll keep walking into others, putting your health and theirs at risk,” Mayor Michael P. Cahill said in a reverse 911 call to residents on Sunday morning. “This includes on our sidewalks. Families, if you need to take walks or bike rides, please stay close to home, and please stay away from other people.”

Those who do need to go out in public are asked to take extra precautions.

“If you need to go out, Dr. Anthony Fauci, American’s lead infectious disease expert, now recommends that we all wear a mask at all times in public,” Cahill said. “Please know that what we – you and I – are doing now, and what we do in the coming days and weeks, will either save lives or cost lives – right here in Beverly. This depends on all of us.”

Cahill also reinforced the need to avoid congregating in groups.

Exactly

[Axtremus]

Need a graph of SARS-Cov-2 relative transitivity vs. distance, with range of 95% confidence and 85% confidence marked.

Do it in 5 dimensions, I want temperature, humidity, and wind speed too.

It's all droplet vs. aerosol, people.
