No appointments are needed and patients can get results within 24 to 48 hours. Officials are expecting to test up to 700 people per day on Wednesday and Thursday. "We need to ensure that our resources are allocated equitably and effectively in order to slow the spread of this virus," Mayor London Breed said in a statement. "By standing up a testing site at 24th and Mission streets that is easily accessible, we are better serving the Latino community and our essential workers, who have been disproportionately affected by the COVID-19 health pandemic. By meeting people where they are with critical resources like testing, we can better protect the health of all of our communities during this current surge, which will help us safely reopen our city."
