HIV is a disease caused by the human immunodeficiency virus, which leads to the progression of acquired immunodeficiency syndrome (AIDS). The virus targets the immune system, specifically the CD4 cells, weakening the body’s ability to fight off infections and diseases. HIV is transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It can also be passed from mother to child during childbirth or breastfeeding. Early symptoms of HIV may include flu-like symptoms, but the disease can progress without noticeable symptoms for years. If left untreated, HIV can advance to AIDS, which is characterized by a severely weakened immune system and an increased risk of opportunistic infections and certain cancers. Treatment for HIV involves antiretroviral therapy, which can control the virus and prevent the progression to AIDS, allowing individuals to live longer, healthier lives.
