COVID-19 cases and deaths

COVID-19 cases and deaths in San Francisco, including new cases and cumulative totals.

New cases

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.

Data notes and sources

View source data

Case information is based on confirmed positive laboratory tests reported to the City.

Cases are shown on the date the positive test was collected.

It takes time to process and confirm these data. Because of this:

  • cases and deaths data lag by several days

  • daily case totals on previous days may increase or decrease

All data update daily as more information becomes available. Learn more about the update process.

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.

View source data

Case information is based on confirmed positive laboratory tests reported to the City. Vaccination data comes from the California Immunization Registry (CAIR2). The California Department of Public Health runs CAIR2. We include vaccination records from counties outside of San Francisco in order to improve matching rates. This allows us to identify breakthrough cases among people who moved to the City after completing their vaccine series. Only cases among San Francisco residents are included in the case rates.

Cases are shown on the date the positive test was collected.

It takes time to process and confirm these data. Because of this: 

  • Case data are lagged by several days.
  • Daily case totals on previous days may increase or decrease.

Case rate calculations:

  • Case rates among vaccinated residents are equal to the number of new cases among vaccinated residents divided by the estimated number of residents that have been fully vaccinated. Individuals are considered fully vaccinated 14 days or more after completing their COVID-19 vaccine series. This number is different than the number of residents that have been vaccinated, which is usually reported as the number of residents that have received at least one COVID-19 dose. 
  • Case rates among unvaccinated residents are equal to the number of new cases among unvaccinated residents divided by the estimated number of unvaccinated residents. The estimated number of unvaccinated residents is calculated by subtracting the number of residents that have received at least one dose of a vaccine from the total estimated resident population. 

Population information is from the 2019 American Community Survey (ACS) 5-year estimates. The U.S. Census Bureau provides these data.

Deaths by month

COVID-19 deaths are shown below. Deaths are shown on the date the individual died.

Data notes and sources

View source data

COVID-19 deaths are suspected to be associated with COVID-19. This means COVID-19 is listed as a cause of death or significant condition on the death certificate.

Deaths may be reported by:

  • Healthcare providers

  • The California Department of Public Health Vital Records

  • Case investigation or outbreak investigation

  • The Office of the Chief Medical Examiner

It takes time to process these data. Because of this:

  • data is lagged by several days

  • monthly death totals for previous months may increase or decrease

All data update daily as more information becomes available. Learn more about the update process.

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.
