Myth 1: rabies vaccine must be injected within 24 hours after being bitten by a dog.
It seems common sense that rabies vaccine must be injected within 24 hours after being bitten by a dog, but epidemiologists think it is a misunderstanding. The treatment method after being bitten by a dog should refer to the "10 day observation method" given by WHO. After the wound is treated and disinfected, it is best to observe the biting dog or cat in isolation. If the dog and cat do not die within 10 days after biting, it proves that the saliva of the bitten dog and cat does not contain rabies virus. According to WHO's research, only a few days before the death of a dog or cat is the infectious period of rabies, and being bitten is very dangerous. If a cat or dog dies during the observation period, people can be vaccinated against rabies instead of being bitten within 24 hours. If it is other animals, do not use the observation period 10 days to fight immediately. Earlier, a spokesman for China CDC said that the "10-day observation method" was not applicable to China because the strains in Asia were different from those in other regions, but the WHO experiment in Thailand proved that the 10-day observation method was effective because only the traditional rabies virus type I was found in all Asian canines. According to the relevant regulations of the World Health Organization, in principle, the earlier the rabies vaccine is injected, the better the effect is, and it is best to inject it within 24 hours. If the vaccine is injected for more than 24 hours, the vaccine can play a role as long as people are not sick before the vaccine stimulates the body to produce enough immune antibodies. Therefore, replanting vaccine is effective. Health and drug supervision departments will also continue to strengthen the monitoring of adverse reactions of rabies vaccine.
Myth # 2: Be vaccinated when bitten or licked by a dog.
According to a researcher from the Genetic Engineering Office of Wuhan Institute of Biological Products, rabies is mainly prevalent in the densely populated southeast of China, as well as in Yunnan, Guizhou and Sichuan. If post-exposure prevention is not carried out at all (that is, rabies vaccine injection), it is estimated that the number of rabies deaths in China will be 30 thousand each year. The annual consumption of rabies vaccine reaches150,000 people, indicating that 99.8% of them could not be vaccinated. In 2008, the US Centers for Disease Control and Prevention issued a report to evaluate the probability of eight possible cases of rabies transmission. Among them, the probability of dog biting, cat licking, dog licking and contact with rabies patients in hospital is the highest, which is 1/65438+ 10,000, and vaccination is usually not needed. About 1 million people are bitten in the United States every year, and only over 10,000 people are actually vaccinated, with a maximum of 30,000 people. Conversely, more than 900,000 people don't need it.
