Texas state health department data shows the vast majority of cases are among people younger than 18: 26 in kids younger than 4 and 51 in kids 5-17 years old. Ten adults have measles and three cases are “pending” an age determination. The Ector County Health Department told the Odessa American its case was in a child too young to be vaccinated.

As Texas continues to battle a growing measles outbreak largely among its unvaccinated children, six other states have confirmed cases, as well.
