AIDS is a chronic, life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging the immune system, HIV interferes with the body’s ability to fight off viruses, bacteria and fungi that cause disease. HIV makes the body more susceptible to certain types of cancers and to infections it would normally resist, such as pneumonia and meningitis.
