The report "Situation of the AIDS epidemic 2009" published by the Joint United Nations Program on HIV / AIDS and the World Health Organization (WHO) reveals that the number of new infections due to the AIDS virus (HIV) ) has decreased worldwide by 17% in the last eight years.
In addition, the report highlights that HIV prevention programs are achieving positive results. In sub-Saharan Africa, cases of HIV infection have been reduced by approximately 15%, which translates to 400,000 fewer infections in 2008. In the same period, in eastern and southern Asia these cases have decreased by about 25% and 10% respectively. In Eastern Europe, the epidemic is relatively stable, despite a significant increase in the number of new infections, especially those caused by injectable drugs.
In some countries, however, there are indications that point to a further increase in the incidence of the virus.
The investigations continue in the areas of pharmacological treatment and in the development of a vaccine. Unfortunately, HIV medications are not always available in developing countries, where the magnitude of the epidemic is much greater.
