Measles Vaccine Demand Drops 75% in Cancún Amid Outbreak

Cancún, Quintana Roo — Demand for measles vaccines in Cancún has dropped by up to 75% for the second consecutive day, health officials reported, even as confirmed cases in the city’s outbreak rose to 41.

Staff at mobile vaccination units visiting local markets, as well as at health centers and hospitals, said attendance has plummeted compared to previous days. Nurses and other personnel administering doses suggested that immunity coverage may have been largely achieved among children and adults following the recent spike in infections.

The federal Health Ministry reported 41 positive cases and 144 suspected cases of measles. Since June 2025, the cumulative total of infections stands at 43, with no deaths reported.

State authorities said they have administered 103,000 measles vaccines to date, with a goal of reaching 376,596 doses over 10 weeks.

Of the 41 confirmed cases, 36 involved individuals who were not vaccinated, three are under investigation to determine if they had completed their vaccination schedule, and two are pending confirmation, according to state officials.

A visit by local media to the market in Region 102, Health Center Number 15, and the General Zone Hospital confirmed the decline in attendance.

Data from the Special System for Epidemiological Surveillance of Febrile Exanthematous Diseases shows that from January 1, 2025, to the present, 28,865 probable cases have been reported nationwide, with 10,941 confirmed as measles.
