[Gender differences in HIV/AIDS].

Women currently have to face a series of additional risk factors for HIV infection, which place them at a disadvantage compared with men. These factors include economic dependence on their partners, difficulties in gaining access to accurate information on infection, prevention, diagnostic tests and counseling, gender violence, and discrimination. These difficulties are demonstrated by the growing epidemic in women, which illustrates the need to guarantee the legal, institutional, social and economic conditions that would enable action to be taken against these factors of inequality. The present article reviews the biological and social factors that influence susceptibility to infection in men and women, gender differences related to health services attendance and disease, and HIV/AIDS preventive measures from a gender perspective. The situation in Europe and the USA has been taken as a reference, although the article is mainly focused on Spain.
