Texas has reported 20 more measles cases in the past 5 days. The outbreak now stands at 561 cases, with 58 patients requiring hospitalization. The outbreak’s epicenter includes counties in West Texas that are home to a large unvaccinated Mennonite community. 

Texas officials said Cochran, Dallam, Dawson, Gaines, Garza, Lynn, Lamar, Lubbock, Terry, and Yoakum counties have ongoing measles transmission. 

Two school-aged girls, both unvaccinated, died in this outbreak. All but 11 case-patients in the current outbreak are unvaccinated or their vaccine status is unknown. Four case-patients have had one dose of the measles, mumps, and rubella vaccine, while seven have had two doses.

Of the 561 cases, 381 are in children 17 years and younger. 

According to the Texas Department of State Health Services tally, El Paso County has 7 cases, but media reports earlier today said 3 new cases have been identified in that city, raising the total to 8. The 3 most recent cases were reported in an unvaccinated female infant, a vaccinated male teenager, and a 30-year-old woman with unknown vaccination status. 

In New Mexico, 5 more cases have been identified since last week, raising the state total to 63. New Mexico’s cases have occurred in counties bordering the Texas outbreak.

In Michigan, Ingham County has reported a measles case in a 1-year-old girl who had traveled outside the state. State officials are still determining exposures, but the media are reporting a farmer's market and a Michigan State University campus.

This is the fifth confirmed case of measles in Michigan in 2025.

In Pennsylvania, Erie County now has an outbreak, with two new cases linked to the first case.

As of last week, the United States now has 712 measles cases, with 93% of cases being outbreak-related (part of 3 or more related cases).
