"offices, schools and events"

transport being 1.7%

I'd be interested in where this data was sourced, as lots of public transportation methods were shut down.

And still are in some places.

source is included

Is this relative to cases per collective, or is this the per capita rate?

2830 cases traced back to their most likely transmission.

You will find the same pattern in most such studies.

You will also find that short flight post very little risk, but that it jumps up to significant as the flight is transcontinental.

same with train-travel.

That's consistent with public toilet use.

indeed it is.

and swab tests from infected cruice ships find the highest probability of an RNA-sample to be positive, when taken from a bathroom floor.

This is the origin of the confusion.

sure, the mask will protect you to some extent from those aerosols, but there is a much more probable pathway.

Touching your face or your food.

after a restroom visit.

I'm surprised to say the least that it was contaminated surfaces that were the primary cause.

But I mean, it makes sense.

We've known it's transmissible via fecal matter for a long time too.

The excretion of virus particles in faces is massive.

ah, yes.

A study from singapore showing a concentration of virus in brown water 200 times higher than was expected based on infection-rate.

that could be silent cases, but still a significant finding.

I'd be surprised if anyone that worked a water treatment plant wasn't infected at some point.

I/C is high for covid 19

interesting point! Ill check for that when I have time.

good thinking. Clever dude/maam.

Cheers!

Includes people that have to work with septic tanks, and utility workers that have to go into into any sewage environment.

well, you dont know its denaturation time exactly, so I would want to check and see if toilet cleaners have a Relative Risk that is significant.

That too.

the singapore study didnt look for operational virii, but RNA fragments.

Water also furthers the expected lifespan of the virus itself.

To potentially weeks.

Its worth reading the cruice ship swab studies too. They found the highest probability on bathroom floors, and the second on pillows.

40 something and 30 something.

I saw one interesting case here, where an entire nursing home got infected, yet the staff had observed all rules and regulations.

why would you put your mask back on before washing your hands

They had been sharing bathrooms, however.
