What is the reason why African swine fever has been repeatedly banned? Why does swine fever spread so fast in China?

African swine fever virus is a contact virus, and many pigs are infected with African swine fever virus through various channels. Therefore, it has brought great difficulty to the prevention and control of African swine fever, which is also the reason why African swine fever has been repeatedly banned. Why does swine fever spread so fast in China? I think there are three main reasons.

First, classical swine fever virus is more complicated. Although Chinese researchers have carried out research and development experiments on it, until now, China has not developed an effective and controllable swine fever vaccine. Not only has it not been developed in China, but it is being released all over the world. No individual or country has announced the development of an effective vaccine.

Experts even said that the research and development of swine fever vaccine is a relatively long-term process. Without vaccine prevention, the epidemic situation of swine fever can only be prevented by chemical prevention and control, and chemical prevention and control is only a temporary solution, and there will always be flaws, so this is also the main reason for the repeated prohibition of the epidemic.

Second, it is related to the present situation of pig industry in China. China is a big pig producer and a big pork consumer in the world. Half of the world's pigs are raised in China, with high breeding density, frequent pig transportation and extensive personnel circulation, which makes it more difficult to prevent and control the epidemic situation of classical swine fever. In addition, some people's understanding of epidemic prevention and control is not high, and the treatment of sick pigs is not standardized enough. Driven by profits, some sick pork is likely to flow to the market, leading to the re-spread of the epidemic virus.

Third, the treatment of African swine fever virus At present, as long as the pig farm is infected with African swine fever, it needs to be completely culled and blocked immediately for harmless treatment. This is the best way to prevent the epidemic from spreading again and will give some subsidies to the corresponding pig farms.

However, it is difficult to identify the epidemic situation of classical swine fever in Africa, or the subsidies for classical swine fever in some areas can not be put in place in time, the treatment and destruction of the virus are not thorough enough, and even the phenomenon of laissez-faire and arbitrary abandonment of sick pigs exists in some areas, which leads to the incomplete elimination of classical swine fever virus and lays the foundation for the outbreak and spread of the virus epidemic in the later period.

To sum up, although African swine fever virus is terrible, it is afraid of high temperature, and it can be completely killed if it exceeds 60 degrees. I think this is the reason why African swine fever virus spreads so rapidly in China. On the occasion of the first anniversary of the outbreak of African swine fever, I sincerely hope that African swine fever can be cleared out in China as soon as possible, so as to give us a clean environment for raising pigs.
