Rabies is not only contagious during an attack. Rabies is spread by animals carrying the virus. When a rabies-carrying animal scratches or bites a person, the virus may enter the body through a skin wound and cause infection. The rabies virus is not only contagious during an attack, but also during the incubation period. During the incubation period, although there are no obvious symptoms of an attack, the rabies virus can be detected in saliva, which proves that the rabies virus is already present in the body, and as long as a person carries the rabies virus, he or she may become infected. Carriers of rabies virus are usually stray cats, dogs, wolves and other carnivores. You should avoid being bitten by these animals in your daily life, and if you are bitten, you should wash the wound immediately and get a rabies vaccination in time.
