Officials hope to change minds amid ‘exquisitely contagious’ measles outbreak

Officials in Clark County, Washington, publish a list every day of where people infected with measles have been. Among them: busy spots like Concourse D at Oregon's Portland International Airport on January 7 and the sold-out Portland Trail Blazers' home game four days later. There's also a Costco, a Trader Joe's, numerous schools, day-care centers and churches, a swimming pool and even a trampoline park.
