San Francisco is training a corps of city workers to trace the contacts of people who may have been exposed to someone suffering from COVID-19. City officials also announced the opening of a new drive-through testing center in the city’s South of Market District for those who may have been exposed to SARS-COV-2, the virus that causes COVID-19. The city is still limiting testing to front-line workers and those who meet the medical criteria for needing a test. Listen to the full press conference audio here.
