Hello, it’s the weekly #washingtonstate #kingcounty (that is, #seattle and environs) #COVID #COVID19 #wastewater toots.
Note that this King County respiratory disease data comes from Washington State, not the federal government.
The West Point (WSPT) sewage treatment plant's Sars-CoV-2 levels 7-Day running average is up pretty strongly from the week before. Last data is from 7/15. If you flip over to the variants tab, you'll see that this site, unlike the other two, is almost entirely XFG and XFC.
WSPT is one of three King County(-ish) sewersheds in this dataset. You can find overviews, individual sewershed results, and a breakdown of variants for the state wastewater surveillance program, along with other metrics like case counts and hospitalizations for Covid-19 and other respiratory illnesses, at https://doh.wa.gov/data-and-statistical-reports/diseases-and-chronic-conditions/communicable-disease-surveillance-data/respiratory-illness-data-dashboard#WasteWater. If you go to the page and click "learn more" in the statewide view tab, you can find out lots of details about how these data are calculated and how to interpret them. The dashboard gets updated every Wednesday (generally). New! the Department of Health is here on the fediweb, at @WADeptHealth
