Opportunistic diseases infect those with compromised immune systems, causing severe health issues like pneumocystis pneumonia and Kaposi's sarcoma.
Opportunistic diseases are infections and tumors that are rare in people with a healthy immune system but common in immunodeficient individuals. These diseases take advantage of a weakened immune system, such as in individuals infected with HIV, causing severe health issues like pneumocystis pneumonia and Kaposi's sarcoma. The term used to describe a disease attacking a person who already has another disease is opportunistic due to its ability to thrive in compromised immune systems.
