Mexico City's Health Secretariat confirmed the death of a 14-month-old baby from measles, which occurred in December 2025 and was validated on February 10, 2026. This is the first death from the disease in the capital amid a national outbreak totaling 28 deaths. Authorities are intensifying vaccination campaigns to curb infections.
The Mexico City Health Secretariat (Sedesa) reported that the 14-month-old girl died in December 2025 during the holiday season, but the death was officially certified only on Tuesday, February 10, 2026, following an epidemiological process. Secretary Nadine Gasman Zylbermann explained that measles did not initially appear on the death certificate, requiring additional studies to confirm it. "This procedure is applied when the cause is not identified immediately," the official detailed.
To date, CDMX has 184 confirmed measles cases, of which 140 are epidemiologically active, with 14 hospitalizations and this single death. Some cases involve people from the State of Mexico who received care in the capital. Nationally, the outbreak totals 8,899 cases from 2025 to 2026, with 28 deaths in seven states: Chihuahua (21), Jalisco (2), and one each in Sonora, Durango, Michoacán, Tlaxcala, and CDMX.
In parallel, on February 10, 2026, Durango reported the death of an 8-year-old boy from measles complications. Local Health Secretary Moisés Nájera Torres stated that the child, from El Mezquital, was admitted gravely to the Maternal and Child Hospital after an infection likely acquired in Sinaloa during a family trip. The family works as day laborers.
In response to the outbreak, CDMX set up 21 vaccination modules with extended hours until 11:00 p.m., prioritizing children aged 1 to 9 and adults up to 49 without complete schedules. Mexico City Mayor Clara Brugada urged to "close the door to measles" through immunization. President Claudia Sheinbaum announced national strategy reinforcements, stressing that "there are enough vaccines" and the need to vaccinate in outbreak areas.
Experts like Alejandro Macías emphasize vaccination as the key measure, noting that masks have "very little utility" against this highly contagious virus, which weakens the immune system and causes complications like pneumonia, encephalitis, and blindness, especially in children under 5 and adults over 30.
