According to the latest CDC wastewater data, 35 states have very high or high levels of COVID-19.

Does AZ just not check or report, or was their data unavailable for another reason? Thanks!

Note: Latest CDC wastewater data is from December 28, 2023, so this doesn't even include the large number of infections that happened over the holidays yet (yikes). And some states are very slow to report their data, so if surrounding states are higher, be skeptical of the lower state (data lag).

What is Oregon doing differently?
