Mexico
Santé Index
Monterrey scores 43.29 (MEDIUM risk) as of 2026-08-07. Measles scores the maximum 100/100, as Nuevo León contributes a proportional share of Mexico's 10,049-case national outbreak (PAHO Situation Report 3, EW1–19), with a state-level estimated incidence of 4.28 cases per 100,000. Dengue is the second driver at 25.2/100, consistent with endemic transmission in the Gulf lowlands region during the summer season. COVID-19 and influenza signals are minimal. No wastewater-based epidemiology program is active in the city. Data are derived from PAHO national proportional estimates at state geographic level. Coverage is high (88%), though values represent proportional allocations from national totals. Conditions are warm and dry (29°C, 68% relative humidity, no precipitation), with heat posing an additional risk for outdoor fans and staff. International arrivals total 4,680. MMR vaccination documentation (two doses) should be required for all accredited personnel and strongly recommended for attendees. Dengue prevention measures — insect repellent, protective clothing, and removal of standing water — apply to all outdoor venues. Medical staff should remain vigilant for febrile illness presentations consistent with either measles or dengue.
