Model-based estimates of transmission indicate continued declines in measles

In a follow-up on the measles outbreak in Mexico, the Ministry of Health reported three additional measles deaths in Zacatecas state (2) and Mexico City, bringing the death toll since the beginning of the year to 16.

Since the outbreak began in January 2025, a total of 43 deaths have been confirmed for the 2025–2026 period, distributed across 11 states: Chihuahua 21, Jalisco 5, Zacatecas 5, Mexico City 4, Durango 2, Chiapas 1, Guerrero 1, Michoacán 1, Sinaloa 1, Sonora 1, and Tlaxcala 1.

From January 1 through June 12, 2026, Mexico has seen 11,665 confirmed cases. Fortunately, model-based estimates of transmission as of EW 21 (through the end of May) indicate continued declines in measles in Mexico.
