[Current situation of HIV/AIDS in the world].

The pandemic of HIV and AIDS has existed for almost 30 years in the clinical setting. Although there was a surprising reaction during the early years in global public health, for the last 14 years, mainly due to the creation of the Joint United Nations Programme on HIV/AIDS (UNAIDS), a systematic epidemiological surveillance of this disease has refined the available data and has allowed the evolution of the epidemic to be monitored more or less in detail. In Mexico, something similar has occurred. In addition to programs of assistance for persons with HIV/AIDS, epidemiological surveillance systems now have robust software platforms that provide data to define the incidence and prevalence of this epidemic reliably. This article presents the most current official information, and a review of the behavior and current situation of HIV/AIDS in the world and in Mexico.
