Health officials in Los Angeles County have confirmed a fourth U.S. case of the new pneumonia-like virus from China.
The Los Angeles County Department of Public Health said Sunday the infected person presented themselves for care once they noticed that they were not feeling well and is currently receiving medical attention.
The person is a returning traveler from Wuhan City, China. The case came on the heels of confirmed cases in Orange County, California, Washington state and Chicago.
The Centers for Disease Control confirmed the Orange County case. The person was also a traveler from the Chinese city of Wuhan — the epicenter of the outbreak — and tested positive for the virus, the Orange County Health Care Agency announced late Saturday. The patient is in isolation at a hospital and in good condition.
The cases in California came on the heels of diagnoses in Washington state, on Jan. 21, and Chicago, on Jan. 24. Both patients — in Washington, a man in his 30s, and in Chicago, a woman in her 60s — had also traveled to China.
Dozens of people have died from the virus in China, which has issued massive travel bans in hard-hit sections of that country to try to stem spread of the virus, and the U.S. Consulate in Wuhan announced Sunday that it would evacuate its personnel and some private citizens aboard a charter flight.
The CDC expects more Americans to be diagnosed with the newly discovered virus, which is believed to have an incubation period of about two weeks, as worldwide the number of confirmed cases nears 2,000. The CDC is screening passengers on direct and connecting flights from Wuhan at five major airports in Atlanta, Chicago, New York City, San Francisco and Los Angeles.
Guidance from the CDC advises that people who have had casual contact with the patient are at “minimal risk” for developing infection. There’s no evidence that person-to-person transmission occurred in Orange County, and the risk of local transmission remains low, the release said. Further details about the case weren’t released.
