Human
immunodeficiency virus (HIV) is a member of the retrovirus family that
causes acquired immunodeficiency syndrome (AIDS), a condition in humans
in which the immune system begins to fail, leading to life-threatening
opportunistic infections. Infection with HIV occurs by the transfer of
blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these
bodily fluids, HIV is present as both free virus particles and virus
within infected immune cells. The four major routes of transmission are
unsafe sex, contaminated needles, breast milk, and transmission from an
infected mother to her baby at birth (vertical transmission). Screening
of blood products for HIV has largely eliminated transmission through
blood transfusions or infected blood products in the developed world.
