Oregon and Washington state in the U.S confirmed 3 patients were infected by unknown means.
The patients — a woman with chronic health conditions, a high school student in Everett, Washington and an employee at a Portland, Oregon school — had not recently traveled overseas or had any known close contact with a traveler or an infected person.
The California Department of Public Health said Friday that the state will receive enough kits from the U.S. Centers for Disease Control to test up to 1,200 people a day for the COVID-19 virus — a day after Gov. Gavin Newsom complained to federal health officials that the state had already exhausted its initial 200 test kits.
Santa Clara County in the San Francisco Bay Area reported two cases where the source of infection wasn’t known. The older woman was hospitalized for a respiratory illness, and rapid local testing confirmed in one day that she had the virus, health officials said.
“This case represents some degree of community spread, some degree of circulation,” said Dr. Sara Cody, health officer for Santa Clara County and director of the County of Santa Clara Public Health Department.
The number of coronavirus cases in the United States is considered small. Worldwide, the number of people sickened by the virus hovered Friday around 83,000, and there were more than 2,800 deaths, most of them in China.
The new coronavirus cases of unknown origin marks an escalation of the worldwide outbreak in the U.S. because it means the virus could spread beyond the reach of preventative measures like quarantines, though state health officials said that was inevitable and that the risk of widespread transmission remains low.
