How much time does HIV live outside the body?
The general response to that question is not long, the HIV is a weak virus and that once exposed to air, it can survive for maybe a few minutes at best.

BUT Under specific conditions, HIV can survive for a far longer period of time, sometimes for hours or even days if the right temperatures, pH balance, light exposure, and humidity are achieved.  It is a very difficult set of conditions but is nevertheless possible.

In certain conditions, the virus can survive outside the body for several weeks.
Survival depends on which body fluid it is in, volume of the body fluid, concentration of the virus within it, temperature, acidity, and exposure to sunlight and humidity.
HIV transmission has not been reported as a consequence of contact with spillages of blood, semen or other body fluids.
