LUBBOCK, Texas (AP) — 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.

The measles outbreak in Texas has now turned deadly. Texas and federal health officials have just reported the first deaths attributed to the still-growing outbreak, which has sickened over a hundred people.

Most kids will recover from the measles, but infection can lead to dangerous complications like pneumonia, blindness, brain swelling and death.

At least 124 people have been infected in the fast-spreading outbreak. Health and Human Services secretary Robert F. Kennedy Jr. said "we have measles outbreaks every year."
