A new case of coronavirus was found in California, becoming the third patient in the United States.

“The OC Health Care Agency (HCA)’s Communicable Disease Control Division received confirmation from the Centers for Disease Control and Prevention (CDC) this evening [Saturday, Jan. 25] that an Orange County, California, case has tested positive for the novel coronavirus,” the agency announced in a press release on Sunday, Jan. 26.

The patient is described as a traveler from Wuhan, Hubei Province, China, and is in isolation in a hospital in “good condition,” CNBC citing the HCA said.

According to the press release, the HCA will monitor any close contacts, but there is “no evidence that person-to-person transmission has occurred in Orange County.”

“The current risk of local transmission remains low,” the HCA said.

In an earlier statement, the CDC also said the U.S. public is not at high risk of transmission, though the situation “continues to evolve rapidly.”

The first case of coronavirus in the United States, announced on Jan. 21, was a Washington state man in his 30s and the second case was an Illinois woman in her 60s. They both traveled to Wuhan, but are currently reported to be in stable condition at area hospitals.

The outbreak of the respiratory illness caused by new coronavirus has so far sickened 2,019 people as of Jan. 25 and killed 56, the majority of which are in Wuhan, according to Johns Hopkins University Center for Systems Science and Engineering (CSSE).

Chinese authorities have restricted travel for 17 cities in Hubei Province, an area encompassing more than 50 million people. Hubei on Sunday shut down intercity and inter-province buses in an effort to curb the outbreak. 

The U.S. Embassy in Beijing on Sunday said its consulate in Wuhan will evacuate its staff and some private citizens on a charter flight on Tuesday to San Francisco, though seat numbers will be limited.

Coronaviruses are a large family of viruses that tend to primarily affect animals, but can evolve and spread to humans. Symptoms for the strain currently moving around the globe include fever, coughing, and shortness of breath, which can progress to pneumonia. Little is currently known about this new strain of coronavirus, and the medical community has yet to develop a cure for it. 

The coronavirus family also includes the SARS virus that broke out in 2003 and infected more than 8,000 people and killed 775, mostly in China.
