⚠️ Warning: The CDC downshifted COVID categories (e.g., High reclassified as "Moderate") mid-wave, without flagging the change as they usually do on their website and without a defensible rationale. This change violates fundamental public health standards and is a part of a broader theme of downshifting public health guidance on the CDC pages in August 2026. We do not recommend using the downshifted CDC map except to contrast with the standard map. A new PMC map will release in October, as it would be imprudent to redraw maps mid-wave.

Prevalence estimates are derived by harmonizing wastewater levels with IHME true case estimates; such estimates are volatile for smaller geographic units, especially for counties that are estimated rather than observed or only have a single monitoring site.
