Who / What
HIV stands for **Human Immunodeficiency Virus**, a retrovirus that attacks the immune system, specifically targeting CD4 cells (a type of white blood cell). Over time, it progresses to **AIDS** (Acquired Immunodeficiency Syndrome), weakening the body’s ability to fight infections and diseases. Without treatment, HIV can lead to severe health complications.

Background & History
HIV is a retrovirus belonging to the **Lentivirus** subgroup of retroviruses. The virus was first identified in the early 1980s through research on cases of rare cancers (Kaposi’s sarcoma) and opportunistic infections affecting gay men, intravenous drug users, and hemophiliacs. The discovery linked these conditions to a new, transmissible infection, marking the beginning of global efforts to understand and combat HIV/AIDS. Key milestones include the identification of HIV as the cause of AIDS in 1983 by Luc Montagnier (France) and Robert Gallo (USA), followed by the development of early antiretroviral therapies in the late 1980s.

In the News
HIV remains a pressing health concern today, with ongoing challenges in **prevention (e.g., PrEP, vaccination research)**, **treatment accessibility**, and **global surveillance**. Recent developments include advancements in antiretroviral therapies that allow people living with HIV to achieve viral suppression, reducing transmission risks. Additionally, the COVID-19 pandemic highlighted disparities in healthcare access for HIV patients, prompting renewed calls for integrated health systems.
