Based on the provided information, it seems the question is referring to AIDS (Acquired Immunodeficiency Syndrome), although there is a spelling error in the original question.
AIDS is a chronic condition caused by the Human Immunodeficiency Virus (HIV). HIV weakens the immune system, making the body vulnerable to infections and diseases.
Here's a breakdown:
- What it is: AIDS is not a disease itself, but a syndrome that occurs in the late stages of HIV infection.
- Cause: It is caused by HIV, which attacks and destroys immune cells (specifically CD4 cells).
- Impact: HIV damages the immune system so that the body is less able to fight infection and disease.
- Chronicity: AIDS is an ongoing (chronic) condition.
