How long can the rabies virus live outside host?

The rabies virus can survive in the environment for several days, but its exact longevity depends on various factors such as temperature, humidity, sunlight, and the type of surface it encounters. In general, it can survive:

- Up to 24 hours on smooth surfaces like metal or plastic at room temperature.

- Several hours in saliva or other body fluids at room temperature.

- Up to a few weeks in soil or water with lower temperatures and higher humidity.

- Longer periods in colder environments or when protected from direct sunlight.

However, it's important to note that the rabies virus is fragile and easily inactivated by heat, ultraviolet light, and common disinfectants. It cannot survive for extended periods outside of a host organism.
