Rabies viruses are generally not indirectly infectious. The rabies virus has a very low resistance in vitro and dies easily after leaving the body. The chance of infection caused by the rabies virus that enters the broken skin and mucous membranes of the human body through indirect means is very low, so the rabies virus does not usually cause indirect infection. Rabies is mainly contracted through direct contact with animals, including bites, scratches, or licking wounds caused by diseased animals. Alternatively, infection can be caused during slaughtering, skinning, etc. Infection does not occur when a person comes into contact with food or utensils contaminated by the saliva of a rabid animal. Although the rabies virus is generally not indirectly infectious, it is important to take precautions not to be scratched by dogs, cats, etc., and not to touch anything that has been touched by a sick animal.
