Vaccine teams in Mexico scramble over measles outbreak rippling out from Mennonite community
- Health authorities in Chihuahua, Mexico, are responding to the largest measles outbreak in decades, centered in the Mennonite community since March 2025.
- The outbreak was linked to an unvaccinated 8-year-old boy from the Mennonite community who traveled to see family in Seminole, Texas, a key area affected by the U.S. Outbreak.
- Low vaccination rates around 70% in the Mennonite community and 76% statewide, combined with widespread vaccine misinformation and distrust, have hindered containment efforts.
- Federal authorities have identified 922 measles infections and a single fatality in Chihuahua, while vaccination teams carry out door-to-door efforts that aim to increase immunization rates while respecting local community practices.
- The outbreak’s spread into Indigenous and other populations and limited vaccination uptake imply challenges remain to controlling measles in the region.
