PMC COVID-19 Data Dashboard



Use the desktop interactive map to scroll over each county for more detail. See the CDC's map for state-level estimates only.

Alert: On Aug 14, the CDC modified how they link numeric wastewater data to level categories in ways that describe current and historical transmission using lower categories (e.g., much of Low is now "Very Low"). We made a brief video explainer; see coverage in NBC News and Forbes. By default, PMC uses the pre-August 14 system. We have added a toggle switch to the interactive map.
