A team of public media reporters are gathering information from California health departments every day to keep you updated on the latest confirmed cases and deaths due to COVID-19. This dashboard provides a localized look at COVID-19-related cases and deaths in your county, as well as a risk assessment for your county’s population.

As of March 23, 2020, case and death data for California counties is collected by hand by reporters for CapRadio, KQED and KPCC from each public health department or county’s individual site each evening. We update the data daily at 7 or 8 p.m, and many jurisdictions post in the late afternoon. Historic data is provided by Big Local News & USA Facts.
While Alameda County and the city of Berkeley report their number of cases and deaths separately, we have added Berkeley’s totals into Alameda County’s totals for this data. Additionally, while Sutter and Yuba counties are one combined health jurisdiction, they sometimes report their data jointly, we have reported them separately here.
The data presented here only includes cases in which a person has tested positive for COVID-19, but it may be lower than the actual number of infected people in a community due to a lack of testing. Not every county updates its numbers daily, so these totals reflect the latest numbers as of our last data collection. Some counties report all people who have tested positive in the county, whether or not the person is a resident of the county.
As counties report cases when test results come in, some of the increases in counties’ cases in one day could be due to many pending results coming in rather than many people coming down with symptoms in one day.
