IMPORTANT The US CDC has announced that, going forward, reported SARS-CoV-2 wastewater levels will be normalized to an endemic baseline "Zero" on this baseline will be levels in the previous year @evanblake17.bsky.social @benjaminmateus.bsky.social

The first chart here are SARS-CoV-2 wastewater levels from 2022 to present prior to baseline normalization The second chart is the same thing but just for 2024 The third is a (predicted) chart for 2025 assuming wastewater levels in 2025 are similar to 2024 Much less scary, eh? That's the intent

It does seem that they will be employing negative numbers, which isn't as bad: "Wastewater Viral Activity Level Calculation: The number of standard deviations that each log-transformed concentration value deviates from the baseline (positive if above, negative if below) is calculated." Still bad tho
