[Advances and challenges for the prevention and control of AIDS in Mexico].

This document aims to give an epidemiological overview of HIV and AIDS in Mexico, to highlight some aspects of both the governmental and nongovernmental response, and to emphasize important challenges in the fight against the epidemic. The HIV and AIDS epidemic in Mexico is confined to specific groups such as men who have sex with men and intravenous drug users. It has low prevalence among general population, a percentage we aim to maintain. Universal access to retroviral treatment in Mexico is an achievement that is sustainable only if a constant reduction of new cases is accomplished. This can only be obtained by preventive measures that are based on evidence. It is necessary to strengthen nongovernmental associations that are working on prevention. In 2009, the number of nongovernmental associations that received official financing was relatively low. It is necessary to improve the epidemic vigilance and evaluation systems. This would allow better follow-up of the activities that confront the epidemic, and to obtain better feedback for the procedures.
