General Discussion

Opportunistic infections are mild to severe infectious diseases in a compromised host. The infections are caused by microorganisms that normally do not cause serious disease in healthy people. These infections may occur in individuals whose immune system or other physiological defenses are impaired or compromised in some way. The inability to resist such opportunistic infections is usually caused by an underlying disease or trauma, or from procedures and/or drugs that are used to treat another medical condition.

Opportunistic infections may be caused by bacteria, fungi, viruses, or parasites. Symptoms vary according to the microorganism involved and the extent of involvement. Treatment or medical management of opportunistic infections may be difficult because some of these microorganisms may be resistant to standard antibiotic therapy. In some cases an affected individual may have a dysfunctional immune system (compromised) that is not able to fight the infection.
