The first cases of measles were detected in 2025 in the state of Chihuahua, where officials identified incomplete vaccination records or a complete lack of vaccination against the virus among a significant portion of patients. This underscores the importance of maintaining high vaccination rates to prevent outbreaks.
Health officials warn that measles is one of the most contagious viruses known, even more so than COVID-19. In response to the increasing number of infections, the Mexican government has announced a strengthening of vaccination programs in strategic locations with high foot traffic, including airports and bus terminals.

According to the National Autonomous University of Mexico (UNAM), individuals born before 1957 likely do not require vaccination, as they probably developed immunity through prior infection or vaccination. This finding could inform targeted vaccination strategies.

However, the Centers for Disease Control and Prevention (CDC) advises that some adults, particularly those in high-risk environments or specific populations, should receive a second dose of the vaccine, as they may spread the virus even without showing symptoms. This highlights the importance of continued vigilance and vaccination even among those who may have been previously exposed.
Health authorities indicate that adults aged 20 to 39 should initiate or complete their vaccination schedule, especially those who do not recall being vaccinated in childhood or lack official documentation.
Vaccination against measles is also recommended for the following groups:
- Children aged 12 and 18 months
- Children aged 2 to 9 years who are behind on vaccinations
- Healthcare personnel
- Education personnel
- Agricultural workers
In addition, a “zero dose” of measles vaccine is being administered to infants aged 6 to 11 months as an early protective measure against the virus and to reduce the risk of community transmission. This proactive step aims to provide immediate protection to vulnerable infants.
