South Carolina's measles outbreak is over. But more are brewing around the country

A health care worker assessed a patient with measles symptoms in Spartanburg, S.C. in January. Strict public health measures and increased vaccination helped curb the outbreak.

The virus infected nearly 1,000 people in the state before the state declared it over. Meanwhile, cases are spreading across many parts of the U.S., with more than 20 outbreaks currently active.
