Sub-Saharan Africa is still the most affected region of the world, where the meridional region presents the largest incidence of all (30%) and contains only 2% of the world population. Asia and Eastern Europe epidemics are still growing, mostly because IVU drug use and sexual commerce. Latin America presents an epidemic concentrated to high risk behavioral groups, especially in South America. Mexico has 71,526 registered cases; the most them between 25-34 years, 51% have died up to date. The main route of transmission is sexual. A lot is still to come in the future years, but we have to pay special attention to the prevention of this disease.
