Human immunodeficiency virus
Human immunodeficiency virus (HIV) is a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).
Overview[edit | edit source]
HIV is a retrovirus that primarily infects components of the human immune system such as CD4+ T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4+ T cells, leading to a weakened immune system.
Transmission[edit | edit source]
HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk.
Symptoms[edit | edit source]
The symptoms of HIV vary depending on the stage of infection. In the early stages, symptoms include fever, fatigue, and rash. In the later stages, symptoms can include weight loss, night sweats, and frequent infections.
Diagnosis[edit | edit source]
HIV is diagnosed through blood tests that detect the presence of the virus or its antibodies.
Treatment[edit | edit source]
While there is no cure for HIV, it can be controlled with proper medical care, including antiretroviral therapy (ART).
Prevention[edit | edit source]
Prevention strategies include safer sex practices, needle exchange programs, and antiretroviral drugs.
