How long does HIV remain infectious outside the body?

HIV, or human immunodeficiency virus, is a virus that attacks the immune system and can lead to AIDS (acquired immunodeficiency syndrome). HIV is transmitted through certain body fluids, including blood, semen, vaginal secretions, and breast milk. It is not transmitted through casual contacts such as shaking hands, hugging, or sharing food or drinks.

HIV does not survive long outside the body. The virus is sensitive to changes in temperature and humidity and is quickly destroyed by exposure to air, sunlight, and heat. HIV is also killed by common household disinfectants and can be effectively eliminated with proper cleaning and disinfection.

In general, HIV is not considered infectious outside the body. It is not transmitted through casual contact or through the air, and it does not survive long in the environment. However, it is important to practice safe behaviors to prevent the transmission of HIV, including using condoms during sexual activity, avoiding sharing needles or other injection drug equipment, and practicing safe infant feeding practices.
