Please note: the California Department of Public Health (CDPH) is experiencing issues with their disease reporting system. As a result locally reported daily and total COVID case counts are currently an underestimate. We are working to resolve this issue locally and awaiting a complete fix from the State. This banner will be removed when the issue is resolved.
We track the number of new cases to show how quickly the virus is spreading.
The 7-day rolling average shows the trend in new cases. We calculate the rolling average by averaging the new cases for a particular day with the prior 6 days.
Recent data are less reliable as test and case data are still being validated. We do not calculate the rolling average for less reliable data.
New cases by vaccination status
The data below on cases by vaccination status are estimates based on case data matched to COVID-19 vaccine data. Individuals are fully vaccinated after 14 days or more have passed from completing their COVID-19 vaccine series. A fully vaccinated case is when someone tests positive for COVID-19 and is fully vaccinated. An unvaccinated case is when someone tests positive and has not received any COVID-19 vaccine. Data are not shown for new cases among partially vaccinated residents.
- No COVID-19 vaccine completely prevents all COVID-19 infections.
- Fully vaccinated cases (also called "breakthrough infections") are expected. This does not mean the vaccines do not work.
- The vaccine's job is to promote a healthy immune response. If you are fully vaccinated and contract the virus, your symptoms will most likely be mild and similar to the common cold.
- Vaccinated people are still highly unlikely to be hospitalized due to COVID-19.
The 7-day rolling average case rate shows the trend in new cases per 100,000 residents by vaccination status. We calculate the rolling average case rate by averaging the new case rate for a particular day with the prior 6 days.
Data for the most recent 8 days may be incomplete and are not shown.
Deaths by month
COVID-19 deaths are shown below. Deaths are shown on the date the individual died.
Total cases and deaths
The total cumulative number of cases and deaths is the running total. The cumulative total will always increase. The steep increases show times with higher daily new cases or more frequent deaths.
