Measles cases rise in Mexico and Ecuador prompt health alerts

In Mexico, the state of Querétaro recorded 45 confirmed measles cases in 2026, a rate of 1.67 per 100,000 residents, with no associated deaths. The national tally stands at 12,225 confirmed infections and 17 fatalities, out of 44,128 reported febrile rash illnesses.

In Ecuador, the Ministry of Public Health activated epidemiological surveillance in Cuenca, Azuay province after identifying a suspected measles case. Authorities are conducting door‑to‑door checks, verifying vaccination records, and offering preventive immunizations. Although Ecuador remains certified as measles‑free, the surveillance is intensified due to a rise in cases across the Americas in 2025 and increased population movement linked to the 2026 FIFA World Cup.
