(CNN) A person infected with measles attended a Portland Trail Blazers home game in Oregon last week amid an outbreak that has left at least 19 people ill this month in neighboring Washington state. Contagious people also went to Portland International Airport, as well as to hospitals, schools, stores, churches and restaurants across Washington's Clark County and the two-state region, county officials said. A public health emergency was declared Friday in Clark County, less than a half hour drive from Portland, in response to the measles outbreak. Of 19 people with confirmed cases, 18 are children, county officials said . The CDC recommends people get the measles, mumps and rubella vaccine to protect against those viruses.
