The measles outbreak in Texas has now turned deadly. Texas and federal health officials have just reported the first deaths attributed to the still-growing outbreak, which has sickened over a hundred people.

A child in West Texas has died of measles, state health officials said on Wednesday, the first reported U.S. death from the highly contagious disease in a decade, as a Texas outbreak has grown from a handful of cases to more than 130 across two states.
