A new coronavirus case in California could be the first in the US that has no known connection to travel abroad or another known case, a possible sign the virus is spreading in a US community, health officials said.
California officials said the person is a resident of Solano County, northeast of San Francisco, and is getting medical care in Sacramento County. They said they have begun the process of tracking down people who the patient has been in contact with, a process known as contact tracing.
All of the 59 other cases in the US had travelled from abroad or had been in close contact with those who travelled.
