Where California stands with coronavirus testing right now

“Something that is missing from our knowledge of this virus is how many people are exposed to it,” said Philip Felgner, director of the vaccine research and development center at the UC Irvine School of Medicine. That data is key for understanding the breadth of the outbreak, and just how lethal it really is. … Here in California, Felgner at UC Irvine has teamed up with a company called SinoBiological to create tests that can hunt for antibodies to nine different infectious agents including other coronaviruses like ones that cause SARS and MERS, as well as viruses that lead to similar symptoms, like influenza.
