　　NEEDHAM, Massachusetts 8 Yue 3 Ri , issued by the Ministry of Agriculture and Rural disease information, Shenyang City, Liaoning Province Shenbei African swine fever outbreak occurred. It is understood that this is the first time in China that an African swine fever has occurred. Regarding the current situation of prevention and control of swine fever in Africa, the reporter interviewed the head of the Veterinary Bureau of the Ministry of Agriculture and Rural Affairs. 　　Reporter: Everyone is very concerned about the African swine fever epidemic in Shenbei New District of Shenyang City. At the same time, it is relatively unfamiliar to the animal disease of African swine fever. Can you briefly introduce African swine fever?
　　Responsible person: African swine fever is an acute, heat and high-contact animal infectious disease caused by African swine fever virus . It can be infected by pigs of all breeds and ages, with the highest morbidity and mortality. Up to 100% . The World Organisation for Animal Health has listed it as a statutory report on animal diseases, and China has classified it as a class of animal diseases. 1921 Nian Kenya's first reported outbreak of African swine fever, the disease in the last century, 60 into Europe's, 70 's passed in South America, 2007 passed in the Caucasus and Russia. Since 2017 , there have been several African swine fever epidemics in the Russian Far East. The disease is now predominantly prevalent in Africa, Central and Eastern Europe and the Caucasus. Direct contact between healthy pigs and sick pigs or pollutants is the most important route of transmission for African swine fever. Pig bites such as poisonous cockroaches also have the possibility of infecting African swine fever.
　　Reporter: Will people infect African pigs?
　　Responsible person: African piglets are not ill to people, not zoonotic diseases, which means that the virus will not infect people.
　　Reporter: What are the main hazards of African swine fever?
　　Responsible person: African swine fever is a serious hazard to pig production. It is understood that the incidence rate is usually between 40% and 85% , and the mortality rate varies depending on the infected strain. Mortality highly pathogenic strain of up to 90 - 100% ; in the middle of the pathogenic strains mortality in adult animals by 20% - 40% between mortality in young animals in the 70% - 80% between The mortality of low pathogenic strains is between 10% and 30% .
　　China is a big country for pig breeding and product consumption. The amount of live pigs and stocks account for more than half of the global total. At the same time, pork is the main source of meat protein for residents. Pork consumption accounts for more than 60% of total meat consumption. The degree of scale is low, and the frequency of pigs is high and the number of pigs is high. If spread in the country, it will cause immeasurable losses to China's pig breeding industry.
　　Reporter: What kind of response work has China done for African pigs?
　　Responsible person: Since the disease was introduced to Russia in 2007 , the Ministry of Agriculture and Rural Affairs has successively issued the ?Technical Regulations for the Prevention and Control of African Swine Fever (Trial)? and the ?Emergency Plan for African Swine Fever?, which has been repeated in high-risk areas such as the northern border provinces. Organize emergency drills and conduct monitoring throughout the country for many years. In 2017 , after the African swine fever epidemic occurred in Irkutsk Region in the Far East of Russia, the Ministry of Agriculture and Rural Affairs immediately issued the ?Emergency Notice on Further Strengthening the Risk Prevention of African Swine Fever?, requiring all localities to be alert to the risk of the epidemic and to ensure the risks. Prevent work.
　　Recently, after the suspected African swine fever epidemic occurred in Shenbei New District, Shenyang City, Liaoning Province, the Ministry of Agriculture and Rural Affairs immediately coordinated the China Center for Animal Health and Epidemiology (National Alien Animal Disease Research Center) to carry out diagnostic work and sent a working group to guide the outbreak. Disposal and troubleshooting work. At present, local pigs have been culled and harmlessly treated in the affected areas, a blockade order has been issued to the affected areas, and pigs in the city of Shenyang have been suspended. The Ministry of Agriculture and Rural Affairs has also informed international organizations about this African swine fever. Other related work is being carried out in an urgent and orderly manner in accordance with the requirements of the Emergency Plan and the Technical Specifications for Prevention and Control.
　　Reporter: How should pig farms do the prevention and control of African piglets?
　　Responsible person: Since there is no vaccine developed in the world that can effectively prevent African swine fever, high temperature and disinfectant can effectively kill the virus, so the biosafety protection of the farm is the key to prevent and control African swine fever.
　　First, strict control of personnel, vehicles and susceptible animals into the farm; personnel, vehicles and articles entering and leaving the farm and its production areas must strictly implement disinfection and other measures.
　　The second is to keep the pigs as close as possible, and take protective measures to avoid contact with wild boar and blunt soft palate.
　　Third, it is strictly forbidden to use pig water or meal waste to feed pigs.
　　Fourth, actively cooperate with local animal disease prevention and control institutions to carry out epidemic disease surveillance and investigation, especially the occurrence of piglet vaccination immune failure, unexplained death, etc., should be reported to the local veterinary department in a timely manner.

merci,

aussi longtemps que la cause ne sera pas identifi?e, des tensions , il va y en avoir .


En g?n?ral ? l'occasion de ce genre de premi?re d?couverte, on peut entrevoir bien des infractions aux r?gles, soit disant, en place.


Voici un exemple historique fran?ais:

"Malgr? les mesures sanitaires et douani?res prises ? la fronti?re franco-espagnole, la maladie a ?t? identifi?e en France en avril 1964. A ce jour 5 foyers ont ?t? mis en ?vidence: 1 dans les Basses-Pyr?n?es, 3 dans les Pyr?n?es-Orientales et 1 dans le Finist?re;"

"Epid?miologie.
- Il est certain que ces foyers ont pour origine l'introduction clandestine en France de porcs espagnols, trafic qui semble, d'ailleurs, d?j? avoir ?t? la cause de quelques cas de Fi?vre aphteuse au d?but de 1964. ?"
