HIV/AIDS

A Blood-borne disease of the human immune system that is characterized cytologically especially by a reduction in the numbers of CD4-bearing helper T cells, to 20% or less of normal, rendering the subject highly vulnerable to life-threatening conditions, such as pneumonia. There are others that become life-threatening (such as Kaposi's sarcoma) and that are caused by infection with HIV. HIV has been found in Blood, semen, saliva, tears, nervous system tissue, breast milk, and female genital tract secretions; however, only Blood, semen, female genital tract secretions, and breast milk have been proven to transmit HIV to others. It is most commonly transmitted in infected Blood and bodily secretions (e.g. semen), commonly during illicit IV drug use and/or sexual intercourse.
