Risk by Gender
In the United States, HIV is spread mainly through anal or vaginal sex or by sharing drug-use equipment with an infected person. Although these risk factors are the same for everyone, some gender groups are far more affected than others. Gay, bisexual, and other men who have sex with men, for example, account for the majority of new infections despite making up only 2% of the population.
