HIV can survive at room temperature outside the body for hours if dry (provided that initial concentrations are high), [31] and for weeks if wet (in used syringes/needles). [32] However, the amounts typically present in bodily fluids do not survive nearly as long outside the body—generally no more than a few minutes if dry. [23]

In 1994, Stephen Crohn became the first person discovered to be completely resistant to HIV in all tests performed despite having partners infected by the virus. [3] Crohn's resistance was a result of the absence of a receptor, which prevent the HIV from infecting CD4 present on the exterior of the white blood cells.
According to the Centers for Disease Control, Ebola on dry surfaces, such as doorknobs and countertops, can survive for several hours; however, the virus in body fluids (such as blood) can survive ...
