Measles cases in West Texas are still rising two months after the outbreak began. Local public health officials say they expect the outbreak to last for at least several more months and the case number is likely an undercount.

A measles outbreak that began in Texas at the start of the year has infected over 300 people as of Tuesday, as cases of the highly contagious illness have been spotted in 17 states and already exceeded the total number of measles cases reported in 2024.
