How are you? The rate the rabies virus can become inactive outside the body depends on factors such as moisture, sunlight and temperature. Studies by Matouch et al show that the temperature of 30 degrees Celsius combined with intensive sunshine devitalized the virus within 1.5 hours, whereas without sunshine the virus may still remain active, at the temperature of 30 degrees C, after 20 hours. Hope this helps. Take care and regards.
Human Rabies Prevention - United States, 1999 Recommendations of the Advisory Committee on Immunization Practices (ACIP)
The contamination of open wounds, abrasions, mucous membranes, or theoretically, scratches, with saliva or other potentially infectious material (such as neural tissue) from a rabid animal also constitutes a nonbite exposure. Other contact by itself, such as petting a rabid animal and contact with blood, urine, or feces (e.g., guano) of a rabid animal, does not constitute an exposure and is not an indication for prophylaxis.
Because the rabies virus is inactivated by desiccation and ultraviolet irradiation, in general, if the material containing the virus is dry, the virus can be considered noninfectious.
