February 5, 2026 - 19:19

A measles outbreak in Mexico has prompted health authorities in the state of Jalisco to issue a public alert. The state, set to host matches during the upcoming FIFA World Cup, is on high alert following confirmed cases of the highly contagious viral disease.

The alert urges the public to verify their vaccination status, particularly ensuring that children have received the measles, mumps, and rubella (MMR) vaccine. Health officials are emphasizing the importance of recognizing early symptoms, which include high fever, cough, runny nose, conjunctivitis, and a characteristic red rash.

This action follows a broader epidemiological alert issued for the Americas region regarding the spread of the preventable illness. The resurgence of measles, which was declared eliminated in Mexico over two decades ago, underscores the critical need for maintained high vaccination coverage to protect public health.

With an influx of international visitors expected for the global sporting event, the alert aims to contain any potential spread. Health services are reinforcing surveillance and readiness to respond to any suspected cases, stressing that vaccination remains the most effective defense against the serious disease.
