A unvaccinated school-age child died in February in Lubbock — the first measles death in the U.S. in a decade. In early March, an adult in New Mexico who was unvaccinated and did not seek medical care became the second measles-related death.

The second death of a child with measles has been reported in West Texas amid an outbreak that has infected hundreds in the region and across state lines.

A spokesperson for UMC Health System in Lubbock, Texas, said that the child was "receiving treatment for complications of measles while hospitalized" and was not vaccinated.
