A patient in Southern California is the third person in the U.S. to be diagnosed with the new pneumonia-like virus from China, health officials said. The Centers for Disease Control confirmed a traveler from the Chinese city of Wuhan — the epicenter of the outbreak — tested positive for the virus, the Orange County Health Care Agency announced just before midnight Saturday. The first known case in California comes on the heels of diagnoses in Washington state, on Jan. 21, and Chicago, on Jan. 24.
