Mexico City

Epidemiological Brief

As of 27 July 2026, Mexico City is classified at MEDIUM epidemic risk (composite score 36.7). Measles is the primary driver, with an estimated incidence of 7.16 cases per 100,000 derived from Mexico's national outbreak (PAHO Situation Report 3, CDMX allocation), reaching 100% of the reference threshold. Mexico City is the highest-traffic venue in this analysis with 13,175 international arrivals, substantially amplifying importation and onward transmission risk. Dengue incidence is low at 0.66 cases per 100,000, with local transmission present but below levels seen in coastal states. Influenza ILI is minimal at 0.1%, and COVID-19 activity is low at 0.39 cases per 100,000. Surveillance data are based on national proportional estimates (Medium coverage tier). Mild and wet conditions (18 °C, 60% humidity, 4.7 mm precipitation) are typical of Mexico City's rainy season and may support Aedes mosquito breeding in standing water. No wastewater-based epidemiology programme is active in Mexico at this time. Recommended actions include mandatory MMR vaccination verification at all entry points, active febrile surveillance with measles and dengue case pathways, rapid isolation protocols for suspected measles cases, vector control around all venues, and daily coordination with Mexico's Secretaría de Salud and CDMX health authorities.
