I don't know the answer. Some guesses: (1) lower severity affects the more severe outcomes (death, ICU, hosp) relatively more. Severity could be lower because (1A) immune escape variants infect those with acquired immunity to a greater extent. Also infections skew younger for same reason.

- 2025 was worst year for flu since 2017 - better identification of flu as cause of death - Covid-19 causing less severe disease due to population immunity - lower Covid-19 prevalence due to population immunity - worse identification of Covid-19 as cause of death (though still better than flu) 2/

Practically though, it appears to have increased the short-time fluctuations in the data. Which probably makes it less useful for detecting changes in the recent trend. So I am a bit surprised that they made the change. 5/5
Prof. Michael Fuhrer (@michaelsfuhrer.bsky.social) reply parent
The change to non-normalized data *might* make sense given that they are interested in producing a number that tracks trends in wastewater RNA. It removes any trend that might be present due to changes in the normalization (e.g. seasonal changes in PMMoV). 4/
Prof. Michael Fuhrer (@michaelsfuhrer.bsky.social) reply parent
They continue to aggregate the data by calculating a z-score, and normalizing to a rolling one-year baseline, before aggregation. Thus the WVAL is still not proportional to RNA copies detected, but rather a number which reflects recent trends. 3/

What could be going on? Infants (ages 0-1) are a new cohort each year, with little acquired immunity. They also aren't drivers of transmission. It's likely that the infection rate in infants simply reflects prevalence in older children and younger adults (families). 6/

Worse, the implication is that there is a simple answer to "how many people are getting infected with covid each day?" which the CDC could provide, but doesn't. (This is incorrect; they can't provide a scientific answer to this.)

What is the harm if Weiland decides to multiply the CDC's WVAL by a number and calling it "daily infections"? The harm comes because some people (including mainstream media) will mistake it for science.
Prof. Michael Fuhrer (@michaelsfuhrer.bsky.social) reply parent
The question here is whether wastewater can be used to estimate the number of infections in a community. The scientific consensus is a resounding "no" (see top post). This is why the CDC doe snot publish such estimates based on wastewater.
Prof. Michael Fuhrer (@michaelsfuhrer.bsky.social) reply parent
Just FYI, as the quote in the top post indicates, wastewater is very good for tracking *trends* in prevalence. The CDC's WVAL is designed to do precisely this, and they publish data weekly so people can track national and local trends. www.cdc.gov/nwss/rv/COVI...

I am fairly certain that he is aware that he has made a serious error in misinterpreting the CDC WVAL as proportional to RNA concentration, which is a central assumption of his analysis. Given that he persists in publishing his estimates, I'd say that's some evidence of probable bad faith.
Prof. Michael Fuhrer (@michaelsfuhrer.bsky.social) reply parent
I think only he can answer that. I suspect he started off by providing what he thought was a useful, if amateur, estimate of covid infections. His work got misinterpreted as expert analysis by some media outlets, and he hasn't disabused them of that notion.
Prof. Michael Fuhrer (@michaelsfuhrer.bsky.social) reply parent
But the biggest problem is that Weiland is claiming to calculate and publish a number that people want to know, and that the CDC isn't publishing. To those who believe that he is trustworthy, the strong implication is that the CDC is *not* trustworthy. This tears down trust in public health.
