Ten-day observation method: As long as the dog or cat that bit you or caught you and other mammals, did not die within ten days, then we can determine that at the time of the bite you do not belong to the attack period, or simply a healthy dog. Then we can rule out the possibility that you have the disease. Even the eleventh day the dog died will not affect. If the dog dies within ten days, it means that the dog is suffering from rabies and carrying the rabies virus. This statement is not reliable, because the mortality rate of rabies is 100%, rabies can be prevented but not treated, the emphasis is on prevention. If the dog dies within ten days after being bitten by the dog, then consider getting the rabies vaccine, it is not as safe as getting the vaccine just after the injury, because the earlier the rabies vaccine is given, the earlier antibodies are produced in the body, and the safer it is. In addition, if the dog does not die within ten days, there is no guarantee that the dog is not carrying the virus, because the dog may not develop the virus. Just like an AIDS patient, a medical examination reveals that there is AIDS, but there are no symptoms, and there may not be any symptoms for many years, although there is HIV in the blood, which is contagious. This situation according to the ten-day observation method will not need to inject rabies vaccine, then there is the possibility of infection. So that the ten-day observation method is not reliable.
