Travelers wearing masks arrive on a direct flight from China, after a spokesman from the U.S. Centers for Disease Control and Prevention (CDC) said a traveller from China had been the first person in the United States to be diagnosed with the Wuhan coronavirus, at Seattle-Tacoma International Airport in SeaTac, Washington, January 23, 2020.

The Centers for Disease Control and Prevention on Wednesday confirmed the first possible “community spread” of the coronavirus in the U.S., found in a patient in California.
The CDC doesn’t know exactly how the patient contracted the virus. The individual is a resident of Solano County and is receiving medical care in Sacramento County.
“At this time, the patient’s exposure is unknown,” the CDC said in a statement. “It’s possible this could be an instance of community spread of COVID-19, which would be the first time this has happened in the United States.”
The patient didn’t have a relevant travel history or exposure to another patient with the virus. The case was picked up by clinicians in the public health system, the agency said. It brings the total number of cases in the U.S. to 60, a bulk of which are people who were evacuated from Wuhan, China or the Diamond Princess cruise ship that was quarantined off the coast of Japan.
“Community spread means spread of an illness for which the source of infection is unknown,” it said, adding that it’s possible the patient contracted the virus from someone who brought the infection back from another country. It’s significant because it means that it’s also possible the infection is spreading untraced throughout the local community.
California’s State Public Health Officer Dr. Sonia Angell said it’s been “an evolving situation, which California has been monitoring and responding to since COVID-19 cases first emerged in China last year. This is a new virus, and while we are still learning about it, there is a lot we already know.”
Earlier this week, CDC officials said that it was just a matter of time before the outbreak starts to spread in the U.S.”We are asking the American public to work with us to prepare for the expectation that this could be bad,” Dr. Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases, told reporters on a conference call.
The announcement from the CDC came just hours after President Donald Trump asserted the risk of the virus to the American public is “low.”
Earlier in the day, U.S. Health and Human Services Secretary Alex Azar confirmed a new case of the coronavirus in the U.S., “the epidemiology of which we are still discerning,” he said while testifying on Capitol Hill.
The CDC said it is working closely with state, local, tribal, and territorial partners, as well as public health partners, to respond to this public health threat. “Unprecedented, aggressive efforts have been taken to contain the spread and mitigate the impact of this virus,” the agency said.
Health officials have said the respiratory disease is capable of spreading through human-to-human contact, droplets carried through sneezing and coughing and germs left on inanimate objects.
