Only four of the five latest confirmed 2019 novel coronavirus infections in the U.S. are people with a travel history to Wuhan, China, the epicenter of the outbreak, according to the CDC’s National Center for Respiratory Diseases. Its director, Dr. Nancy Messonnier, said at a press briefing yesterday that the fifth patient – who is in California - is a close household contact of another patient in California. This is the second instance of person-to-person spread in the United States.
The new cases bring the total of coronavirus cases in the U.S. to 11, and Messonnier said there will likely be more.
