In February 2021, the Chinese Journal of Veterinary Medicine published the research paper "Identification of a Natural variant of African Classical Swine Fever virus" completed by the Institute of military Veterinary Medicine, Academy of military Medicine, Academy of military Sciences. The article said that recently, in view of the slowing down of the epidemic of classical swine fever in Africa and the low mortality rate of infected pigs in China, the research team studied the ecology of African classical swine fever virus. A natural variant of African classical swine fever virus was isolated from a place in Hubei Province.
It can be said that what we have been worried about has happened, the African classical swine fever virus has mutated.
It is reported that at present, there are mainly two kinds of so-called virus mutations: one is the natural variation of the virus, and the other is the mutation caused by the illegal use of the so-called "African classical swine fever vaccine."
The industry believes that the variation of the African classical swine fever virus strain is very tricky, but what is even more frightening is the illegal use of the vaccine. Because the illegal use of vaccines is more harmful than natural variation. After all, the mutation of the virus has brought great challenges to vaccine development and prevention and control.
For a long time, people have pinned their hopes on vaccines to eradicate African classical swine fever. after all, there is no vaccine, and pigs will never be insured, but it is precisely because of this that there has been a chaos of "emergency medical treatment" and the application of illegal vaccines. To this end, the General Office of the Ministry of Agriculture and villages issued a notice to severely crack down on the illegal development, production, operation and use of African classical swine fever vaccine.
