wastewater concentrations of the coronavirus are similar to what they were at the start of the first winter surge in 2020.

 

Data from Biobot Analytics, a biotechnology firm that has partnered with the CDC, shows that wastewater concentrations of the coronavirus are similar to what they were at the start of the first winter surge in 2020.

But now that the vast majority of people in the US have some immunity to Covid-19 through vaccination, infection or both, those same viral concentrations could translate to a larger number of infected individuals with milder — but still contagious — infections.

The upward trend is clear

Even if the exact number of new infections isn’t clear, experts say, the rising trends in the data that is available are enough to raise alarm.

“Surveillance data is across a continuum. We want to have multiple different types of data that tell us different kinds of things. When they’re all pointing in the same direction, that’s maybe a time to get even more concerned,” Hamilton said.
