Illustrations of AIDS

AIDS
AIDS (acquired immune deficiency syndrome) is caused by HIV (human immunodeficiency virus), and is a syndrome that leaves the body vulnerable to a host of life-threatening illnesses. There is no cure for AIDS, but treatment with antiviral medication can suppress symptoms. AIDS is universally fatal, in large part due to the proliferation of opportunistic infections.

Primary HIV Infection
HIV (human immunodeficiency virus) is more frequently transmitted through unprotected sex or sharing contaminated needles. Transmission from mother to fetus or through blood products has significantly declined in the United States.


Antibodies
Antigens are large molecules (usually proteins) on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, drugs, and foreign particles. The immune system recognizes antigens and produces antibodies that destroy substances containing antigens.
