Daily cases and deaths
California has 3,618,695 confirmed cases of COVID-19, resulting in 59,772 deaths.
Note: Numbers do not represent true day-over-day changes as these results include cases from prior to yesterday. Episode date is the date the event is estimated to have taken place. Reported date is the date the event was reported to the California Department of Public Health. Cases includes people in state and federal prisons, US Immigration and Customs Enforcement facilities, US Marshal detention facilities, and Department of State Hospitals facilities. These groups are excluded from the Blueprint tier assignment calculations, which show different case and test positivity rates. A negative number of reported deaths means that deaths previously attributed to COVID-19 were determined to not be associated with COVID-19.
