With a backlog of coronavirus test results now flowing into a state database, California reported 13,149 coronavirus cases on Monday, with additional older results expected to increase daily totals throughout the week.

“The issue with the state’s electronic laboratory reporting system has been addressed and the system is now performing as expected,” the California Department of Public Health said in a media statement Monday. “The entire backlog has been completely eliminated, and new cases attributed to the backlog will be reported over the next few days.”
