> What is PMMoV normalization? > In addition to the pathogens it tests for, WastewaterSCAN measures an extremely common, harmless plant virus that is consumed when people eat. It is called pepper mild mottle virus (or PMMoV). By measuring the concentration of PMMoV genetic markers per dry weight gram of wastewater solids, WastewaterSCAN can account for how much viral material is recovered from each sample and changes…

The strength will mostly be a constant scale factor, hence proportional to.

The primary mechanism these things are spread by is water droplets in the air expelled from the nose and mouth. A sick person wearing a mask will expel more moisture into the mask, and less into the air. None of this is binary. It's not sick or not sick. There is a viral load component, where a persons body can fight off a certain amount of virus.

Someone sick should be staying home, not going into grocery stores with a mask on.

How else would they get food? Not everyone can afford to order in. Is your opinion that these people should just starve?

I am continually surprised at how many people don’t wear masks at places like the grocery store even as cases are rising. I got covid over the summer and it was horrible! I lost two weeks of work which was a lot of money to lose, missed multiple dates with my partner I would have really enjoyed and felt totally isolated. Then I felt fatigue and brain fog for months afterwards. Afterwards I got the bivalent vaccine so…

Masks are unlikely to have protected you much unless it’s a tight fitting n95 mask worn around the clock. This topic has been beaten to death on here, not sure why people continue to cling on to masks as anything other than security theater.

Masks are primarily for protecting other people, you cough and sneeze and breathe out infected water droplets into the mask- not other people's faces.

Why do people like you have such anger about mask wearing?

Can't believe we're still arguing about whether pErSoNaL rEsPoNsIbIlItY will save us

Because it's not security theater, as has been demonstrated time and again FFS It's trivially easy to acquire authentic N95s today. People just won't wear them, so, we all suffer.

Austria has mandated N95s for months.

No improvement in comparison to neighboring countries could be demonstrated.

Mostly because it was pure theater and no attempt at proof was even made.

I am not disagreeing. However, the premise of normal masks is primarily for sick people to not spread disease.

"It is important to wear a mask or respirator when you are sick or caring for someone who is sick with COVID-19."

https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-si...

"Wear a high-quality and well-fitting mask if you must be around others (for example: going to get tested), even in your home."

https://www.health.state.mn.us/diseases/coronavirus/sick.htm...

Framing masking as protecting the wearer was done to psychologically make people care. People are more likely to care about themselves, than others.

I guess I’m skeptical, isn’t the majority of covid spread through prolonged close contact? Running into a grocery store without a mask for fifteen minutes seems extremely low risk compared to other activities.

You're contagious for 2 days before you have symptoms. You should wear a mask if you're around other people.

Not disagreeing. I am pointing out the mask is to block the spreader, moreso than shield the recipient.

I remember during the tail end of the pandemic someone posted a link to a big spike in wastewater COVID testing in our city's sewers. So I decided to pay close attention to the COVID test rates/hospitalizations for the next 2 months. But I never ended up seeing any correlation. The trendline stayed stagnant, before declining as it did everywhere else. I know that's a one-off non-scientific example, but it made me won…

It’s been extremely reliable in Boston.

We Europeans are continually surprised that talking about masks is still a thing.*

Except for 1 or 2 outlier countries masking is over.

* Unless they are familiar with U.S. politics
