Why is AIDS considered to be a ‘Syndrome’ and not a disease ?
AIDS causing virus – HIV that comes into the body via the sexual organs or any other means like blood transfusion will spread to lymph nodes all over the body. The virus damages the immune system of the body and due to this the body can no longer fight off many minor infections.
