Introduction: Opportunistic infections


Opportunistic infections: Opportunistic infections are those infections that are uncommon except when they are given an "opportunity" to infect a person. The opportunity is usually a problem with the immune system, which can occur as a secondary infection (because the immune system is busy fighting some other chronic illness), or can occur for people whose immune system is compromised (see immunocompromised). A common type of opportunistic infection is a nosocomial infection, which is contracted during a hospital stay while the patient is ill or recovering. People can be immunocompromised from certain diseases (especially AIDS), certain medications (e.g. immunosuppressants or chemotherapy), surgical recovery, or other serious medical complaints that limit the person's ability to mount an immune response to these opportunistic infections.

Treatments for Opportunistic infections: Various information is available about treatments available for Opportunistic infections, or research treatments for other diseases.

Causes of Opportunistic infections: Research more detailed information about the causes of Opportunistic infections, other possibly hidden causes of Opportunistic infections, or other general information about Opportunistic infections.
