Health officials in Santa Clara County said they have identified at least three other people who died at home from COVID-19 before the first documented death in the Northern California county on March 9. The local medical examiner collected samples during autopsies performed on people who died on Feb. 6, Feb. 17, and March 6 that later tested positive for the novel coronavirus. Officials said in a news release that the "testing criteria set by the [Centers for Disease Control and Prevention] at the time restricted testing to only individuals with a known travel history and who sought medical care for specific symptoms" and they expect to identify additional COVID-19-related deaths. More than 825,000 people in the U.S. have been sickened by COVID-19 and at least 45,000 have died, according to data aggregated by Johns Hopkins University.
