Summary

A measles outbreak in western Texas has grown to 198 cases, with 39 new infections in the past three days, according to state health officials.

Most cases involve unvaccinated individuals or those with unknown vaccination status, and at least 23 people have been hospitalized.

A school-aged child, unvaccinated, has died—the first U.S. measles death in a decade. Health officials urge vaccination, as cases continue rising, especially in counties with high exemption rates.

The CDC is assisting Texas officials in containing the outbreak.
