Experts: avian influenza may occur in cold resistant areas of Northeast China

Introduction: Heilongjiang channel of the first Xinhua network reported that based on the cold and heat-resistant characteristics of the avian influenza virus, experts pointed out that the possibility of the occurrence of avian influenza is not ruled out in the cold area of Northeast China, and it is also necessary to improve vigilance and intensify prevention and control The National Avian Influenza Reference Laboratory of Harbin Institute of veterinary medicine, Chinese Academy of Agricultural Sciences, TXI is the only scientific research institution in China that conducts the final virus isolation and identification of avian influenza virus According to Dr Tian Guobin of the laboratory, the avian influenza virus is generally unstable at 4-40 ℃ and can only survive for a short time, while it can survive for a long time below - 10 ℃ Therefore, it is wrong to say that the temperature of TXI area in the northeast is low, and the avian influenza virus cannot survive On the contrary, it is more necessary to strengthen monitoring in cold areas and carry out emergency preventive immunization when necessary TXI Tian Guobin reminded that in order to effectively prevent avian influenza, farmers should strengthen the immunity of birds and carry out comprehensive prevention and control, strictly restrict the access of personnel and vehicles in daily breeding places, and disinfect on time Farmers and veterinarians need to strengthen their own protection and report to the relevant departments in time in case of a large number of poultry deaths While avoiding panic, citizens should buy poultry and products that have been quarantined by the quarantine department TXI Tian Guobin said that since winter and spring are the frequent periods of avian influenza, and the diversity of transmission modes of avian influenza virus, for example, it is possible to spread by leaps and bounds, active measures should be taken in areas where avian influenza has not yet occurred, so as to prevent the disease in advance TXI is easy to prevent and treat SARS Dr Tong Guangzhi, deputy director of Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences, said in an interview that as long as the measures are appropriate, avian influenza is easier to prevent and treat than SARS TXI Tong Guangzhi explained that the avian influenza virus has high morbidity, high mortality and high risk, which is mainly manifested in the harm to poultry Its host has a certain specificity, so it will not easily infect people Avian influenza virus is widely spread in animals The source of infection is clear Once confirmed, measures such as killing and compulsory immunization can be taken to prevent and control it directly, effectively and definitely TXI Tong Guangzhi said that human beings have a long history of research on influenza virus, with rich experience and mature diagnostic methods and vaccine preparation technology At present, Harbin Veterinary Research Institute is carrying out isolation and identification of the avian influenza virus in China After the identification results are obtained, the vaccine can be targeted according to the virus subtype To be sure, the technical control of avian influenza virus is easier than SARS According to Tong Guangzhi, according to the requirements of the Ministry of agriculture, Harbin Veterinary Research Institute has a certain amount of inactivated vaccines of different subtypes of avian influenza In case of an epidemic, it can be used for emergency prevention and immunization of poultry in the surrounding areas to effectively control the spread of the epidemic TXi
