Dogs that do not die 10 days after aggressive behavior can usually be excepted from rabies virus infection, but it cannot be completely ruled out and rabies vaccination is still recommended.
The World Health Organization pointed out that the “10-day observation method” is globally applicable, 10 days is the World Health Organization deliberately extended the safety observation period, the bite of the animal did not die, basically can judge that people are not infected with rabies.
The incubation period for rabies in dogs is 3 to 8 weeks, but it is not contagious during the incubation period. It is only when the virus enters the central nervous system that it begins to multiply in large numbers, and the multiplied virus enters the salivary glands from the brain, at which point the dog is infectious.
So the dog is only contagious a few days before the onset of the disease and at the onset of the disease. And dogs, cats and other warm-blooded animals in the rabies attack within 3 to 5 days after 100% will die, so the attack on people when the infectious dog will generally die within 10 days.
However, China is a high-risk country for rabies, and the rate of preventive inoculation for cats and dogs is generally low, and the Chinese Center for Disease Control and Prevention (CDC) has made it clear in the Technical Guidelines for Rabies Prevention and Control (2016 Edition) that preventive treatment should begin immediately after rabies exposure. Injured persons should also be vaccinated against rabies immediately after ensuring that they are given proper wound treatment.
Once rabies develops, the mortality rate is 100%, so after being scratched or bitten by a mammal such as a dog or cat, it is recommended that you go to the CDC for rabies vaccination immediately after clearing the wound with soap and water, and don’t take any chances.
