More people are now testing themselves at home for COVID-19. We do not get data from at-home testing. This affects the accuracy of case and testing data. Other dashboards that help show the spread of COVID-19 are hospitalizations and test positivity.
New cases
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
Data notes and sources
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.
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. A primary vaccine series is complete after an individual has received all intended doses. There are currently one, two, and three-dose primary vaccine series available, depending on the vaccine brand and the individuals age. A completed series case is when someone tests positive for COVID-19 and completed their primary vaccine series at least 14 days earlier. 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.
- Cases among people who have completed their primary series are expected. This does not mean the vaccines do not work.
- The vaccine's job is to promote a healthy immune response. If you completed your primary vaccine series and contract the virus, your symptoms will most likely be mild and similar to the common cold.
- Vaccinated people are still less likely to be hospitalized due to COVID-19 than unvaccinated people.
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.
Data notes and sources
Data notes and sources
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 cases among people who moved to the City after completing their primary 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 residents who have completed their primary vaccine series are equal to the number of new cases among residents who have completed their primary vaccine series divided by the estimated number of residents that have completed their primary vaccine series. A primary vaccine series is complete after an individual has received all intended doses. There are currently one, two, and three-dose primary vaccine series available, depending on the brand of vaccine and the individuals age.
- 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 2020 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
Data notes and sources
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.
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.
