An infection that develops only when a person's immune system is weakened.

opportunistic infection
There are many different opportunistic infections and many different ways to treat them.
These infections are called "opportunistic infections." They are called opportunistic because a weakened immune system is necessary for them to cause serious infection.
Opportunistic Infection
Phase III
The ones who might already have an infection or have a low immune level.
An opportunistic infection (OI) is an infection that occurs only when the host's defense systems (ie, the immune system) are weakened. The common characteristic of all agents that cause opportunistic infections is that they rarely affect individuals with healthy immune systems. For example, the disease AIDS (acquired immunodeficiency syndrome) is a classic cause of immune system depression and is associated with many opportunistic infections, including toxoplasmosis, pneumocystis pneumonia (PCP), and others.
opportunistic infection
An opportunistic infection is a pathogen that only causes disease in a host with a weakened immune system or other underlying condition. These infections take advantage of the weakened state of the host to cause illness.
AIDS
Examples of opportunistic infections in HIV positive individuals include Pneumocystis jirovecii pneumonia, cytomegalovirus infection, cryptococcal meningitis, and Mycobacterium avium complex infection. These infections take advantage of the weakened immune system and can cause serious illness if not treated promptly. Early detection and proper treatment are crucial for managing opportunistic infections in HIV positive individuals.
