HIV is primarily transmitted through specific routes involving the exchange of body fluids. The main modes of transmission are unprotected sexual contact, sharing of contaminated needles or syringes, transfusion of contaminated blood or blood products, and mother-to-child transmission during pregnancy, childbirth, or breastfeeding. Eating contaminated food/water, inhaling polluted air, or casual contact like shaking hands do not transmit HIV.
Understanding the modes of transmission of Human Immunodeficiency Virus (HIV) is crucial for preventing its spread.
HIV targets the immune system, specifically CD4+ T cells, leading to Acquired Immunodeficiency Syndrome (AIDS), a condition characterized by severe immune deficiency making the body vulnerable to opportunistic infections and cancers.
