Measles (麻疹) breaks out in the Northwest

The U.S. is experiencing outbreaks of measles, a disease it had declared eliminated years ago, largely due to a drop in vaccination (接种疫苗) rates in some communities.

An outbreak in Washington state has sickened 23 people this month, mostly children under 10. Local health officials in Clark County, declared a public-health 1 on Friday. They also urged residents to track 2 symptoms and call ahead before heading to medical centers.
