The outbreak — which includes 124 people — has led to the country's first measles death since 2015, as vaccination rates continue to decline in the U.S.

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.
