(CNN)A person who later learned they were positive for Covid-19 attended a California religious service on Mother's Day, exposing 180 other people to the novel coronavirus, according to local health officials.

The individual got a positive diagnosis for Covid-19 the day after the service and is now in isolation at home, Butte County Public Health said in a statement Friday.

People who attended the service have been notified about their exposure and received instructions from health officials to self-quarantine, the statement said. Officials are working to get testing for everyone who was in attendance.

As of Sunday afternoon, California had more than 78,800 cases of coronavirus, according to data from Johns Hopkins University. More than 3,200 people in the state have died.
