🧠 Explanation:

The Pasteur Institute in France was the first to isolate the HIV (Human Immunodeficiency Virus) in 1983. HIV is the virus responsible for causing AIDS (Acquired Immunodeficiency Syndrome), which weakens the immune system, making the body more susceptible to infections and certain cancers. The discovery by the Pasteur Institute, led by Luc Montagnier and his team, was a milestone in medical research, enabling better diagnostic methods, treatment strategies, and awareness about the virus. Understanding such breakthroughs is important for both medical studies and general knowledge exams like PPSC, highlighting the role of research institutions in global health advancements.
