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.

A child died from the measles after being hospitalized in Lubbock, the first death amid an outbreak that began last month in the South Plains region, health officials said. The Texas Department of State Health Services confirmed the school-aged child's death on Wednesday but did not offer any additional details about the child's age or identity.

The death was a 'school-aged child who was not vaccinated' and had been hospitalized, the Texas Department of State Health Services said in a statement.
