A growing number of Central Texas health departments are warning residents of possible exposure to measles, the latest sign that the outbreak in West Texas is spreading across the state. Why it matters: Measles is a highly contagious and potentially life-threatening disease that has surged in areas with high vaccination exemption rates.

The Hays County Health Department has issued an alert of a potential measles exposure in San Marcos. The San Antonio Metropolitan Health District has issued an alert of a potential measles exposure there.

On February 21, the Texas Department of State Health Services (TDSHS) reported 32 more measles cases in the South Plains region, boosting the state's total to 90 cases. Most are in Gaines County, where the outbreak is centered in the Mennonite community.
