How long does the AIDS virus last outside body?

HIV, the virus that causes AIDS, is a fragile virus and does not survive long outside the human body. It is primarily transmitted through contact with infected body fluids, such as blood, semen, and vaginal fluids.

Outside the human body, HIV is rapidly inactivated by exposure to air, sunlight, heat, and common disinfectants. The virus cannot survive for more than a few minutes on surfaces or objects, and it is not transmitted through casual contact, such as touching or shaking hands.

Additionally, HIV cannot multiply or replicate outside of human cells. It requires specific conditions and host cells to survive and spread, which are found within the human body.

Therefore, the transmission of HIV is mainly limited to unprotected sex, sharing contaminated needles or syringes, blood transfusions with infected blood, and from mother to child during pregnancy, childbirth, or breastfeeding. Regular testing, safe sex practices, and preventive measures can significantly reduce the risk of HIV transmission.
