New testing guidelines from the California Department of Public Health recommend testing people in high-risk settings even if they don't have symptoms.
The new guidelines are aimed at health care workers, prisoners and the homeless. The California Department of Public Health released the testing guidelines in a memo dated Sunday that was first reported by the Los Angeles Times.
Recent outbreaks have hit two California homeless shelters in Los Angeles and San Francisco. Most of the people infected in the San Francisco shelter did not have symptoms.
California is now testing an average of 14,500 people per day.
