Being bitten by an abnormal animal requires vaccination. The pathology of rabies virus is to attack animal brain cells and cause rabies attacks. At this time, animals usually have very obvious abnormalities and are easy to identify.
At this time, the saliva of animals is toxic (virus) and contagious. If you are bitten by such animals, you must get rabies vaccine.
Besides vaccination, we should also observe animals. In view of the fact that warm-blooded animals such as dogs and cats die within 3-5 days after the onset of rabies (some documents mention that they die within 8 days), 3-5 days before death is the infectious period, and there is a danger of being bitten.
Even if you are bitten, if you bite a cat (dog) within 10 days, don't worry, because the bite is not in the infectious period.
10 day is a special extended safety observation period of the World Health Organization. If the cats and dogs are not dead, it can be judged that people are not infected with rabies, and rabies vaccination can be terminated.
