AIDS
AIDS (Acquired Immune Deficiency Syndrome) is a condition resulting from infection with HIV, where the immune system becomes severely weakened and less able to prevent or control infections.
In parasitology, AIDS is especially important because reduced immune function increases susceptibility to opportunistic parasites and can lead to more severe disease, prolonged infection, or dissemination beyond typical sites.
Why it matters: Immunocompromised hosts may experience atypical presentations and higher parasite burdens, and infections that are mild in healthy individuals can become life-threatening.
