The 10-day observation method means that after 10 days of holding animals that have bitten people, if these animals do not develop disease within 10 days, the person who was bitten is considered 100% safe. The 10-day observation method is one of the rabies prevention methods recommended by the World Health Organization, and they can be fully implemented in these developed countries in Europe and the United States, but cannot be fully implemented in China because there are still a certain number of rabies cases that strike each year. Especially in these rural areas where the economic and sanitary conditions are backward, if an animal bites inadvertently, having a person wait 10 days before getting rabies vaccination may miss the best prevention period and lead to rabies attacks, so the ten-day observation method depends on the specific conditions. If the animal is a domestic animal and the rabies vaccine is given twice a year and the bite is not serious, the ten-day observation method can be adopted.
