Mayor of San Francisco London Breed declared a state of emergency in the city amid concerns about an international outbreak of coronavirus, reports The Hill.
According to her, although no cases of coronavirus have been confirmed in the city, "the global picture is changing rapidly" and it is necessary to "strengthen preparedness".
"We see that the virus is spreading in new parts of the world every day, and we are taking the necessary steps to protect San Francisco residents from harm," she was quoted as saying.
The state of emergency will allow city authorities to gather resources and personnel to speed up emergency planning measures and increase the ability to respond quickly to potential coronavirus cases in the city.
Breed's statement came amid warnings from US health officials about the possibility of a virus outbreak in the United States.
So far, 57 cases have been confirmed in the United States, including 40 passengers evacuated from the Diamond Princess cruise ship quarantined in Yokohama, Japan.
