Hawaii also reported two cases of measles in travelers who were infected in Washington before their visit to the Big Island.
The first case in this outbreak has been traced to an international traveler to Clark County who had contact with community groups with low vaccination rates, Wiesman said. Washington Department of Health officials identified 11 health care facilities, 13 schools and child-care centers and over 100 public places, including stores, where people may have been exposed to the virus, he said.
