Mexico City

Epidemiological Brief

Mexico City carries the highest epidemic risk score (57.6) among all 2026 FIFA World Cup host venues. The city is affected by a major active measles outbreak: an incidence of 13.1 per 100,000 reflects Mexico's nationally reported epidemic of more than 10,000 cases through Epidemiological Week 19, with CDMX accounting for a significant share. Influenza-like illness activity is at near-peak levels (ILI% 78.4%), representing heavy respiratory disease burden entering the tournament period. COVID-19 activity is moderate at 2.4 per 100,000. The HIGH risk classification reflects the convergence of these three elevated components. Incoming travelers and World Cup personnel should verify two-dose MMR vaccination and current influenza immunisation prior to arrival. Venue medical stations at Estadio Azteca should maintain febrile-rash triage capacity, dedicated respiratory illness isolation areas, and direct linkage to CDMX Secretaría de Salud rapid-response teams. Pre-travel consultation is strongly recommended for immunocompromised individuals and unvaccinated persons. Immediate medical evaluation is advised for any fever-with-rash presentation or acute respiratory illness onset during the tournament.
