In addition to these two children's deaths in Texas, a third death was reported in a New Mexico resident that was possibly linked to the outbreak. The Centers for Disease Control and Prevention (CDC) is still conducting an independent investigation to confirm that the third death is related to the outbreak.

A second child in Texas has died of measles, according to the Texas Department of State Health Services, in a growing outbreak that has infected hundreds of people, the vast majority in unvaccinated communities in Texas.
