Rabies, commonly known as mad dog syndrome and hydrophobia, is a zoonotic disease caused by rabies virus infection, which mainly invades the central nervous system of human beings. Human rabies is usually transmitted to humans by the bite of diseased cats and dogs. Worldwide, dogs are the main hosts of the rabies virus, so the source of rabies in China is mainly diseased dogs, and then mammals such as cats, pigs, cows, and horses, and non-mammals do not transmit the rabies virus. The virus is mainly transmitted through bites, that is, it can be caused by scratches or saliva contamination of existing wounds or mucous membranes by animals carrying the virus. The incubation period for rabies varies, with most cases developing within 1-3 months, and the onset of the disease is characterized by insomnia, anxiety, delusions, difficulty swallowing, fear of water and wind, and eventually coma and death from heart or lung failure.
