Scanning electron micrograph of HIV-1, colored green, budding from a cultured lymphocyte. HIV is the cause of the spectrum of disease known as HIV/AIDS.

Visna-maedi virus. The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans. Over time, they cause acquired immunodeficiency syndrome (AIDS), [1][2] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.

A bottle containing Stribild tablets (medication used to treat HIV). Stribild is a combination drug containing tenofovir disoproxil fumarate, emtricitabine, elvitegravir and cobicistat. Highly active anti-retroviral therapy (HAART) in many cases allows the stabilization of the patient's symptoms, partial recovery of CD4+ T-cell levels, and ...
