Washington State Becomes Latest Hot Spot in Measles Outbreak

The U.S. is experiencing outbreaks of measles, a disease it had declared eliminated years ago, largely due to a drop in vaccination rates in some areas.

An outbreak in Washington state has sickened 23 people this month, mostly children under 10. Local health officials in Clark County, near Portland, Ore., declared a public-health emergency on Friday and are urging residents to track potential symptoms and call ahead before heading to medical centers.
