Step-by-step explanation:
The HIV-1 pandemic is a global health issue caused by the Human Immunodeficiency Virus (HIV) that has spread rapidly since its identification in the 1980s. HIV is primarily transmitted through sexual contact and the sharing of needles by intravenous drug users.
The virus has had a devastating impact, particularly in sub-Saharan Africa, where it first emerged and remains most prevalent. The development of antiretroviral drugs has transformed HIV infection from a fatal to a chronic disease, with the drugs reducing viral levels and decreasing the risk of transmission and progression to AIDS.
