Washington state has reported a 10th death from the new coronavirus and California announced its first.

Health officials in Northern California say the elderly man who had other health conditions died Wednesday at a hospital in Roseville where he was in isolation.

The man was likely exposed to the virus while he travel in February on a Princess cruise ship from San Francisco to Mexico, officials said in a statement

The Washington state Department of Health released updated figures Wednesday morning, showing that nine people had died in King County, the state’s most populous, and one person in Snohomish County.

Washington state has now reported 39 COVID-19 cases, all in the greater Seattle area.

No other information about the newly reported Washington state death was immediately available.

Researchers at the Fred Hutchinson Cancer Research Center and the University of Washington on Sunday said they had evidence COVID-19 may have been circulating in the state for up to six weeks undetected.

If true, that could mean that there are hundreds of undiagnosed cases in the area.

Also - U.S. officials say a medical screener at the Los Angeles International Airport has contracted the coronavirus.

The U.S. Department of Homeland Security says it’s unclear if the person contracted the virus through their work as a medical screener or from community transmission. The agency said no travelers screened at LAX have tested positive for coronavirus.

The person, who is a contractor for the Department of Homeland Security, is being quarantined at home and has mild symptoms.

The patient last worked at the airport on Feb. 21 and began feeling cold-like symptoms on Feb. 29. The patient’s doctor tested them for coronavirus on March 1.

Officials say the screener wore protective equipment at the airport.

Meanwhile, six new cases of the coronavirus have also been confirmed in Los Angeles County, where there was one previously.

The county public health director says Wednesday the cases confirmed Tuesday night were due to a known exposure and not the result of so-called community transmission.

One person is hospitalized and five others are in self-quarantine at home.

Officials say the cases are from throughout the county, but specific locations were not made public.

The county's first case was in January and involved a person who lived in Wuhan, China.

That person is no longer infectious.
