The Stony Brook Volunteer Ambulance Corps (SBVAC), the university’s collegiate emergency medical services (EMS) agency founded in 1970, is made up of 39 trained student volunteers. The organization, which usually responds to 900-1000 calls a year, including helping overwhelmed local EMS, became essential workers in a global health crisis.

The university, which has tested more than 3,000 students since Aug. 11, said that 17 students have tested positive for the virus. This brings the total number of confirmed cases on campus to 18, after the first case was reported on Aug. 28.
