Consequences

What can happen as a cause of the disease?
HIV kills Helper T cells which in turn are unable to activate B cells and Killer T cells (necessary for immune health). The body becomes defenseless against microorganisms and rare diseases, thus creating room for opportunistic infections (OI).

Common OI's:

Candidiasis (Thrush) - a fungal infection of the mouth, throat, or vagina.

Cytomegalovirus (CMV) - a viral infection that causes eye disease that can potentially lead to blindness.

Herpes simplex viruses - can cause oral herpes (cold sores) or genital herpes. These are fairly common infections, but if you have HIV, the outbreaks can be much more frequent and more severe.

Malaria - is common in the developing world. It is more common and more severe in people with HIV infection.

Mycobacterium avium complex (MAC or MAI) - is a bacterial infection that can cause recurring fevers, general sick feelings, problems with digestion, and serious weight loss.

Pneumocystis pneumonia (PCP) - is a fungal infection that can cause a fatal pneumonia.

Toxoplasmosis (Toxo) - is a protozoal infection of the brain.

Tuberculosis (TB) - is a bacterial infection that attacks the lungs, and can cause meningitis.
