Where the evidence comes from

California's respiratory virus dashboard reports weekly flu, COVID-19, and RSV indicators at statewide and regional levels, including test positivity, healthcare use, and wastewater.

How to read it

Select the region and reporting week before comparing trends. Statewide and regional averages conceal variation among counties and cities, and these indicators do not measure every infection.

Source guide reviewed 2026-11-03. Agency reports have their own update dates.
