Guadalajara

Epidemiological Brief

As of 27 July 2026, Guadalajara is classified at MEDIUM epidemic risk (composite score 44.1). Measles is the dominant concern, with an estimated incidence of 80.1 cases per 100,000 derived from Mexico's national outbreak (PAHO Situation Report 3, cumulative EW 1–19, Jalisco state allocation) — the highest measles signal among all 16 host cities and at 100% of the reference maximum, reflecting the severity of the ongoing national outbreak. Dengue incidence is also notable at 3.49 cases per 100,000, the highest dengue figure among Mexican venues, consistent with Jalisco's endemic transmission during the rainy season. COVID-19 activity is low at 0.60 cases per 100,000, and influenza ILI stands at 0.1%. Data are derived from national-level PAHO proportional estimates (High coverage tier). International arrivals are substantial at 2,610. Warm and occasionally rainy conditions (23 °C, 67% humidity, 4.5 mm precipitation) support both Aedes mosquito activity and indoor respiratory crowding. Priority actions include mandatory MMR vaccination verification for all spectators, enhanced vector control and standing-water elimination around all venues, active dengue surveillance with rapid diagnostics for febrile travellers, rapid isolation protocols for suspected measles cases, and real-time coordination with Mexico's Secretaría de Salud and Jalisco state health authorities.
