Mexico City is facing a growing measles outbreak, with cases climbing to 263 as of February 16, 2026, prompting authorities to prepare several large-scale vaccination centers to curb the spread of the virus. The situation is particularly concerning given a recent fatality: a 14-month-old girl died from complications of measles in December 2025, marking the first measles-related death in the capital this year. This surge in cases and the tragic loss underscore the importance of vaccination efforts to protect vulnerable populations from this highly contagious disease.
The Secretary of Health for Mexico City, Nadine Gasman Zylbermann, has reported that a second potential measles-related death is currently under investigation, though it has not yet been confirmed. Twenty-three individuals have required hospitalization due to the illness. A significant factor contributing to the outbreak is low vaccination rates; 77% of those infected had no prior vaccination record, according to health officials. Notably, 27 of the confirmed cases originated in the State of Mexico, indicating potential spread from neighboring regions.
Focus on High-Risk Areas and Vaccination Efforts
The boroughs (alcaldías) experiencing the highest concentration of measles cases are Gustavo A. Madero, Álvaro Obregón, Cuauhtémoc, Iztacalco, Coyoacán, and Iztapalapa. Health authorities are intensifying sanitary brigades and implementing epidemiological containment measures in these areas to limit further transmission. These measures include targeted vaccination campaigns and close monitoring of contacts of confirmed cases.
Since the start of the vaccination campaign in August, over 1.19 million doses of the measles vaccine have been administered, with 1,192,63 doses given as of February 16, 2026. A recent intensification of the vaccination drive in the past week alone resulted in 270,977 doses administered, reaching a peak of 41,139 vaccinations in a single day. Currently, 140 vaccination points are operational, supported by 560 vaccinators, alongside 300 additional brigades focused on epidemiological containment and outreach.
Community Response and Coordination
Secretary Gasman Zylbermann expressed gratitude for the public’s response to the call for vaccination, emphasizing that community participation is crucial to controlling the outbreak. She highlighted the coordinated efforts between health institutions, capital city dependencies, and federal forces to strengthen coverage and accelerate collective protection against the disease. The success of these efforts relies heavily on widespread participation and adherence to public health guidelines.
The current outbreak is a reminder of the importance of maintaining high vaccination coverage to prevent the resurgence of preventable diseases. Measles is highly contagious and can lead to serious complications, especially in young children and individuals with weakened immune systems. Symptoms typically include high fever, cough, runny nose, and a characteristic rash. Vaccination remains the most effective way to protect against measles and prevent its spread.
Understanding the Rise in Cases
The resurgence of measles in Mexico City, and nationally, is linked to declining vaccination rates in recent years, particularly during the COVID-19 pandemic. According to Dr. Gasman Zylbermann, there have been 8,459 confirmed cases nationally and 27 deaths across 32 states and 300 municipalities. In Mexico City, 178 cases have been confirmed, prompting a more aggressive preventative response. The goal is to “close the door” to measles by increasing immunity within the community, particularly among children and those who may not have received the vaccine.
Authorities are urging anyone unsure of their vaccination status to get vaccinated. The vaccine is available free of charge at health centers, Metro stations, Metrobús stations, and RTP stations, as well as at 21 iconic sites open until 11:00 PM, and through house-to-house brigades in priority colonies. The expanded access points aim to make vaccination as convenient as possible for residents.
The situation remains fluid, and health officials will continue to monitor the spread of the virus and adjust vaccination strategies as needed. Updates and information on vaccination locations can be found through the Mexico City Secretary of Health. The ongoing vaccination campaign represents a critical step in protecting the health of the community and preventing further complications from this preventable disease.
