Mumps Bump: Cases Rise In Iowa, Illinois And Arkansas
There's a bump in the number of cases of the mumps this year in the United States.
This highly infectious disease is much less hazardous than it was decades ago, but health officials are still reacting strongly to several big outbreaks.
Most years, health officials report a few hundred cases of mumps, but this year the total has topped 4,000. Most are clustered in Iowa, Illinois and, worst of all, Arkansas, which has more than 2,200 cases.
