Dr. Sandra Treviño-Pérez
“The Mexican public system serves more than sixty million people. Patient-facing information about it has to reflect what actually happens at the bedside, not how it looks in policy documents.”
Public-System Leadership. Private Practice. Patient-Facing Standards.
Dr. Sandra Carlota Treviño-Pérez is a Mexican internal medicine specialist who leads HIV care policy at the Instituto Mexicano del Seguro Social (IMSS) — Mexico’s largest public healthcare network, serving more than sixty million people. She works within the División de Excelencia Clínica, part of the Coordinación de Innovación en Salud at the Dirección de Prestaciones Médicas, the senior administrative body that sets clinical care standards across IMSS hospitals nationwide.
In addition to her IMSS leadership role, Dr. Treviño-Pérez maintains active clinical practice in Internal Medicine at Médica Sur in Mexico City, with a declared focus on HIV/AIDS care. Her dual role — public-system policy alongside private-sector clinical work — gives her a rare cross-sector view of how Mexico’s HIV care landscape actually functions for patients.
Dr. Treviño-Pérez is the first author of the IMSS national framework on HIV care, Atención a Personas Que Viven Con VIH En El IMSS (Rev Med Inst Mex Seguro Soc, 2022), which documents the institute’s pioneering work in antiretroviral provision — including the 2020 migration to single-tablet integrase inhibitor regimens and the 2021 launch of Mexico’s first national HIV pre-exposure prophylaxis (PrEP) program at the institutional level. She is also a co-author on multi-institutional Mexican HIV resistance research alongside Dr. José Antonio Mata-Marín and the GERA-1 IMSS national committee.
For SunnyPharma, Dr. Treviño-Pérez reviews clinical content on HIV care delivery in Mexico, antiretroviral access through the IMSS public system, and the practical realities patients face when navigating between public-sector enrollment, private-sector practice, and cross-border medication sourcing. Her review covers clinical claims, accuracy regarding Mexican care delivery, and fair representation of public-system strengths and limitations.
The Mexican public system serves more than sixty million people. Patient-facing information about it has to reflect what actually happens at the bedside, not how it looks in policy documents.
