How long can HIV and syphilis survive outside the body?

HIV needs to rely on body fluids to survive, if there is no body fluid dependence, at room temperature, basically in a few minutes to a few hours will die, if there is body fluid dependence, survival time will be longer, may be in 1-2 weeks so. Treponema pallidum if it is in a relatively dry environment, survival time will not exceed an hour.
