This is what Harrison's 16 th edition mentions about HIV transmission

HIV infection is predominantly a sexually transmitted disease (STD) worldwide. Although in the United States ~42% of new HIV infections are among men who have sex with men and ~33% of new HIV infections are by heterosexual transmission, the most common mode of infection worldwide, particularly in developing countries, is clearly heterosexual transmission. Furthermore, the yearly incidence of new cases of AIDS attributed to heterosexual transmission of HIV is steadily increasing in the United States, mainly among minorities, particularly women in minority groups
