San Francisco Mayor London Breed made an emergency declaration on Tuesday in response to the global outbreak of the novel coronavirus.

Why it matters: COVID-19 infections have spread from China to some 40 countries and territories. There are 57 cases in the U.S. The CDC anticipates it will spread further, and that's why Breed said she took the action. While there have been no confirmed cases among San Francisco residents, three people have been treated for the virus in hospitals in the city, the Los Angeles Times notes.

A person in California who hadn't traveled to a country impacted by the novel coronavirus nor had any known contact with anyone infected by the virus has tested positive to COVID-19, the CDC said in a statement.

Why it matters: Per the CDC, "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. Community spread means spread of an illness for which the source of infection is unknown." However, the patient may have "been exposed to a returned traveler who was infected," the CDC noted. "At this time, the patient's exposure is unknown," it said.

New York City and Los Angeles both announced plans Sunday night to close all bars, restaurants and entertainment venues in an effort to curb the novel coronavirus spread.

New York City Mayor Bill de Blasio said only pick-up and delivery would be allowed from restaurants.
