California Coronavirus Cases and Deaths

Track the spread of COVID-19 by state

Data Updated Sep 18, 2020

Coronavirus cases continue to grow in California. From cities to rural towns, stay informed on where COVID-19 is spreading to understand how it could affect families, commerce, and travel. Follow new cases found each day and the total number of cases and deaths in California. The county-level tracker makes it easy to follow COVID-19 cases on a granular level, as does the ability to break down infections per 100,000 people. This county visualization is unique to USAFacts and will be updated with the most recent data as frequently as possible. The underlying data is available for download below the US county map and has helped government agencies like the Centers for Disease Control and Prevention in its nationwide efforts.
