More than 130 people have been infected with measles across Texas and New Mexico. The previous measles death in the U.S. occurred in 2015.

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 cases of measles have been identified in Texas since late January, mostly among children and teenagers who are either unvaccinated or whose vaccination status is unknown, officials say.
