UC San Diego Chancellor Pradeep Khosla on Tuesday alerted students, faculty and staff that the university’s wastewater monitoring system detected SARS CoV-2 — the virus which causes COVID-19 — in multiple sites on Sunday and Monday.

“Our early detection system identified active virus in the wastewater outflow in the five campus areas from 11 a.m. on Sunday, November 22 to 1 p.m. on Monday, November 23,” Khosla said.
