Four people were diagnosed with measles after an outbreak last summer that probably began with a 15-year-old Burmese refugee traveling from Malaysia to Los Angeles, the Centers for Disease Control and Prevention said Thursday.
The teenager arrived in Los Angeles on Aug. 24 and was taken to a hospital with a fever and a rash. He was diagnosed with measles a few days later.
Health officials also diagnosed three other people with measles, including two young passengers on the refugee’s plane and a customs officer who processed him after arrival. The passengers were a 1-year-old L.A. County girl who had not yet completed her vaccination doses, and a 19-month-old girl from Indonesia who had not been vaccinated.
Because the plane carried refugees bound for other locations throughout the U.S., the measles outbreak investigation spanned several states, including California, Nevada, North Carolina and Wisconsin.
