Viral
Step-by-step explanation:
AIDS refers to one of the most life-threatening disease that develops in the human body due to the human immunodeficiency virus, which is commonly known as HIV. It develops at a much slower rate, taking about 10 years of time, affecting the entire immune system of human beings. The full form of AIDS is Acquired immunodeficiency syndrome.
It is a chronic disease that is transmitted sexually and also due to the transmission of infected blood.
