These interventions align with a public health approach based on primary prevention, early diagnosis, and full availability of preventive supplies. Thus, the State of Mexico maintains a comprehensive strategy that combines clinical, community, and health policy actions, fostering an environment where timely detection, universal access to treatment, and evidence-based prevention are articulated as pillars to control the epidemic. This structure allows for articulating preventive actions with civil society organizations, educational institutions, and municipal governments, expanding the capacity for screening, counseling, and extended hours in medical units.
As part of the intensified strategies this year, the Health Institute of the State of Mexico (ISEM), through its Epidemiology Subdirectorate headed by Marco Antonio Montes de Oca González, reported that from January to November, more than 20,000 rapid tests were performed for suspected HIV, which made it possible to identify and refer more than 1,500 people with possible exposure. 6.6 million condoms and more than 40,000 treatments drive risk reduction.
The State of Mexico consolidated in 2025 a standout performance in HIV care, positioning itself as the entity with the first place nationally in undetectability, a critical indicator that confirms the sustained efficacy of antiretroviral treatment and, consequently, a substantial reduction in the risk of transmission. During the same period, 73,928 consultations were provided to people with a confirmed diagnosis, and formal clinical follow-up is maintained for 12,972 patients, reflecting a consolidated and continuously operational care network.
Combined prevention continues to be a central axis. In 2025, 157 people have started this preventive scheme, including six pregnant women, for whom close clinical surveillance is maintained since only one person—the mother or child—lives with HIV. Macarena Montoya Olvera maintains universal treatment coverage through a network made up of six Ambulatory Centers for the Prevention and Care of AIDS and Sexually Transmitted Infections (CAPASITS) and four Comprehensive Hospital Care Services (SAIH), distributed to ensure therapeutic continuity, timely supply, and comprehensive clinical follow-up for people living with HIV.
In the period mentioned, the state health sector carried out 21,105 tests for sexually transmitted infections, provided more than 40,000 treatments, and distributed 6 million 640 thousand 125 condoms, actions considered essential to reduce both the incidence of HIV and other STIs in the population. In parallel, Post-Exposure Prophylaxis (PEP) is guaranteed as an immediate intervention in occupational, non-occupational, and sexual violence contexts, with more than 600 care provided so far this year, reinforcing the early response to possible virus exposures.
Epidemiological surveillance for STIs has also been strengthened. The entity expanded access to Pre-Exposure Prophylaxis (PrEP) in specialized units and first and second-level services.
