The US death toll from coronavirus infections rose to 11 on Wednesday as new cases emerged around New York City and Los Angeles, while Seattle-area health officials sought to allay anxiety amid the nation’s largest outbreak.
Health officials said the first California death from the virus was an elderly person in Placer County, near Sacramento. He had underlying health problems and was likely exposed on a cruise ship voyage between San Francisco and Mexico last month.
It marked the first coronavirus fatality in the United States outside of Washington state, where 10 people have died in a cluster of at least 39 infections that have emerged through community transmission of the virus in two Seattle-area counties.
Although the Placer County patient who died was not believed to have contracted the virus locally, that case and a previous one from the Bay Area linked to the same ocean liner have led health authorities to seek other cruise passengers who may have had close contact with those two individuals.
Hours after that death was announced, California Governor Gavin Newsom declared a statewide emergency in response to the coronavirus, which he said has resulted in 53 cases across the nation’s most populous state.
“The State of California is deploying every level of government to help identify cases and slow the spread of this coronavirus,” Newsom said in a statement.
Six new coronavirus patients were confirmed in Los Angeles County, public health officials said on Wednesday. One was a federal contractor who may have been exposed while conducting medical screenings at Los Angeles International Airport, the US Department of Homeland Security reported.
Three others likely were infected while traveling recently to northern Italy, one of the areas hardest hit in the global outbreak. Of the six in Los Angeles County, only one has been hospitalized. The other five are recovering in home isolation.

The greater Seattle region represents the biggest concentration of cases detected in the United States from a virus that has killed more than 3,000 people worldwide, mostly in China, where the epidemic originated in December.
The fact that most Seattle-area cases are not linked to travel or exposure to people who might have been infected abroad means the virus has gone from being an imported phenomenon to taking up residence in Washington state, health officials say.
At least 18 cases, including six deaths, were connected to a long-term nursing facility for the elderly, called LifeCare Center of Kirkland, in a Seattle suburb.
