AIDS?
ØHuman
immunodeficiency virus (HIV) infection may cause acquired immunodeficiency
syndrome (AIDS).
ØAlthough
characterized by gradual destruction of cell-mediated (T cell)
immunity,
AIDS also affects humoral immunity and
even autoimmunity through the central role of the CD4+
(helper) T lymphocyte in all immune reactions.
ØThe
resulting immunodeficiency makes the patient susceptible to opportunistic
infections, cancers, and other
abnormalities that define AIDS.

retrovirus transmitted by contact with infected blood or body fluids
