Abstract
Introduction: Measles is a highly contagious viral disease that can be prevented by vaccination. Although Mexico achieved endemic elimination, outbreaks associated with declining vaccination coverage have been reported in recent years.
Objective: To describe the current epidemiological situation of measles in Mexico, the
impact of the vaccination program, and clinical control strategies.
Materials and methods: Narrative review based on indexed scientific literature,
institutional documents, and international epidemiological reports.
Results: Vaccination coverage has fallen below the 95% threshold required for herd
immunity. Between 2025 and 2026, a nationwide outbreak was recorded with thousands
of confirmed cases. The primary susceptible population consists of unvaccinated children
and young adults.
Conclusions: The reemergence of measles reflects accumulated gaps in immunization. It
is essential to strengthen universal vaccination, epidemiological surveillance, and timely
management in health services.
