During the 2024–2025 biennium, PAHO provided strategic support to strengthen the Mexican Social Security Institute (IMSS)–Bienestar as a cornerstone of efforts to expand health coverage for populations without social security coverage in Mexico. 

The HEARTS initiative was scaled up nationally in Mexico, with key technical assistance provided by PAHO to accelerate the strengthening of the country’s response to noncommunicable diseases (NCDs) during the biennium. Support focused on the development of clinical pathways for diabetes and hypertension; training of health personnel in quality improvement methodologies and self-assessment of primary  health care (PHC) facilities; and hands-on support to facilitate the institutional adoption of the model.  

Within the framework of the Disease Elimination Initiative, PAHO supported the implementation of a population-based trachoma prevalence survey in five highly vulnerable municipalities in Chiapas, as part of efforts to assess and sustain the status of elimination of trachoma as a public health problem in Mexico. 

PAHO made a decisive contribution to strengthening emergency health preparedness and response in Mexico through technical and financial support for the certification of a type 2 emergency medical team (Centro Operativo para la Atención de Contingencias - COPAC), ensuring compliance with international standards for clinical care in critical situations.  

Within the framework of national efforts to strengthen health emergency preparedness and response, PAHO supported the consolidation of an integrated national genomic surveillance platform aimed at the timely detection, monitoring, and characterization of public health threats.
