The U.S. recorded its first measles death in a decade this week as the largest outbreak of the disease in Texas in 30 years has spread. Why it matters: The outbreak comes at a time of dropping vaccination rates and declining trust in public health institutions.

An unvaccinated, school-aged child in Texas has died of the measles amid an ongoing outbreak in the state that has so far infected at least 124 people, mostly children, sending at least 18 to the hospital. Additionally, nine measles cases have been confirmed across the border in New Mexico.
