Transgender women who have sex with men have the highest risk for HIV infection. HIV has also been found in extremely low, non-infectious amounts in other fluids (saliva, tears and urine) but no transmissions through these fluids have been reported to the CDC.Īccording to the Centers for Disease Control and Prevention (CDC) the largest number of new diagnoses in the United States were among men who have sex with men (MSM), which includes gay and bisexual men as well as men who do not necessarily identify themselves in that way. Blacks and Latinos are disproportionately affected by HIV compared to other racial and ethnic groups. Sex allows for the exchange of certain body fluids that have consistently been found to transmit HIV: blood, semen, rectal and vaginal secretions. In the United States, sexual contact is the most common way that HIV is passed from person to person.
