Rabies can occur after a human is bitten by a dog. The incubation period for rabies varies in length, from a minimum of 4 days to a reported maximum of more than 10 years, with most infected individuals developing the disease within 1-3 months. The onset of rabies can occur within a short period of time after a dog bite and is related to the size of the wound and the amount of infected virus, as well as the location of the wound. If the wound is large, the number of infected viruses is high, and the distance to the brain is close, the incubation period may be short and the disease will develop quickly. If the bite is minor, the incubation period is longer, and the longest reported incubation period for patients can reach 10-20 years. It is also related to the physical fitness of the patient, and people with weak constitutions are prone to attack. Once rabies strikes, the mortality rate is 100% because the rabies virus causes neurological and respiratory failure and death by the time it reaches its onset. If you are scratched and bitten by ordinary dogs and cats, etc., timely rabies vaccination can effectively reduce the chances of infection. If the dog or cat that bites a person does not suffer from rabies, it will not transmit the rabies virus.
