Opportunistic infections

Opportunistic infections occur in people whose immune systems have been weakened by a disease, such as AIDS. An opportunistic infection may cause serious, even life-threatening, illness.

Opportunistic infections that are common in people who have AIDS include Pneumocystis pneumonia, tuberculosis, and toxoplasmosis. Treatment for opportunistic infections depends on the type of infection and the original disease.
