COVID-19 wastewater data now shows that the record spread of the virus in San Diego is beginning to fall.

“We’re coming off the surge for sure,” said UC San Diego Professor Rob Knight. “However, it’s possible that cases will continue to rise or maybe peak around now.”

Knight leads the project that has been analyzing San Diegans sewage from the Point Loma treatment plan over the last two years. He said wastewater is a leading indicator of the virus’ spread, with data typically three weeks ahead of confirmed cases.
