HIV is capable of surviving outside the human body for a period of several weeks in certain conditions, according to NAM AIDSmap. The body fluid in question and the quantity of the virus contained in the fluid affect the survival period, as does temperature and acidity.
NAM AIDSmap states that HIV can live in dried blood at 4 degrees Celsius for a period of at least one week. Extreme cold does not have much of an impact on the virus, although high temperatures of over 60 degrees Celsius do. While HIV can survive outside the body, spilled bodily fluids, such as blood and semen, have not been linked to HIV transmission. Many healthcare professionals do come in contact with such fluids without becoming HIV-positive.
