Abstract
A documentary analysis of historical, normative, epidemiological, and scientific sources of the structural conditions linked to measles in Mexico was performed to describe the disease's trajectory, examine vaccination coverage gaps, and understand the factors that favored its reemergence after regional elimination. Following the interruption of endemic transmission in 1995 and regional elimination in 2016, the disease reemerged in 2025-2026 in a context of accumulation of susceptible population, incomplete vaccination schedules, and territorial inequalities in access to health services. The outbreak concentrated in territories with suboptimal coverages and higher social vulnerability, which evidenced that the sustainability of elimination does not depend solely on vaccine availability, but also on the health system's capacity to maintain homogeneous coverages, sensitive epidemiological surveillance, and timely responses to case importation.
