Opportunistic infections are infections that occur more frequently and are more severe in individuals with weakened immune systems compared to those with healthy immune function. These infections are caused by pathogens that typically do not cause disease in a person with a robust immune response.
Opportunistic infections can be due to bacteria, viruses, fungi, or parasites. They often exploit vulnerabilities in the immune system that may result from various factors, including chronic diseases, malnutrition, immunosuppressive therapies, or conditions like HIV/AIDS. For example, a person living with HIV/AIDS may develop Pneumocystis pneumonia (PCP), a type of fungal infection that is rare in individuals with normal immune function.
In clinical settings, opportunistic infections are of significant concern for immunocompromised patients, as they can lead to severe illness and complications. Preventive measures, such as prophylactic medications and vaccinations, are often employed to protect at-risk individuals from these infections.
Opportunistic infections are infections that occur more frequently or are more severe in individuals with weakened immune systems, such as those with HIV/AIDS, cancer, or undergoing immunosuppressive therapy. These infections take advantage of the weakened immune response to cause illness.
Opportunistic infections can range from fungal infections like candidiasis to bacterial infections like tuberculosis, and viral infections like cytomegalovirus. These infections can be serious and even life-threatening in individuals with compromised immune systems. Early detection and treatment are crucial in managing opportunistic infections and preventing complications.
