LUBBOCK — A person who was hospitalized with measles has died from measles in West Texas, the first death in an outbreak that began late last month. Texas Tech University Health Sciences Center spokesperson Melissa Whitfield confirmed the death Wednesday. It wasn’t clear the age of the patient, who died overnight.

At least 124 people were known to be infected in West Texas since early February, Texas health officials announced, most of them children. An additional 9 cases were announced on Tuesday, in eastern New Mexico, near the Texas state line where the outbreak has spread to about 10 counties, Texas health officials said.

A measles outbreak in rural West Texas has claimed the life of an unvaccinated child, marking the first U.S. measles-related death since 2015.
