We investigate and track COVID-19 data in schools to ensure we re-open safely.
This COVID-19 data is for the entire 2020-2021 school year. We include all COVID-19 cases in San Francisco schools. That includes Transitional Kindergarten through 12th grade.
Cases and transmissions in school
From September 23, 2020 to June 11, 2021, there were 175 cases among 47,615 students or staff. Of these 175 cases, 7 were instances of suspected in-school transmission. In-school transmission means that a student or teacher contracted COVID-19 while at school.
The majority of cases in students or staff are not a result of in-school transmission. Most cases contracted COVID-19 in their family or community outside of school.
San Francisco Unified School District (SFUSD) began reopening schools on April 12, 2021.

Safety is the top priority in schools
All schools that open for in-person learning must follow all public health guidance. This ensures San Francisco schools open as safely as possible. This guidance includes specific procedures on ventilation, face coverings, physical distancing, and more. If anyone at school has symptoms or tests positive for COVID-19, the school must:
-
Ensure that exposed staff and students quarantine
-
Alert the City
The City documents and investigates each case. Learn more on the San Francisco Department of Public Health website.
