洪涝灾害地区动物疫病形势分析

Risk Analysis of Animal Diseases in Flood Disaster Regions

入夏以来,我国多数省份出现连续强降雨天气,洪涝灾害已导致15万头反刍动物、66万头猪、2996万羽家禽死亡,直接经济损失超过53亿元。综合分析当前气象因素、自然生态因素以及动物免疫情况,预期未来一定时期,我国口蹄疫、高致病性禽流感、猪瘟等重大动物疫情区域性流行风险低,但炭疽、血吸虫病、猪链球菌II型、钩端螺旋体病等自然疫源性疾病的地方流行风险增高,痢疾等条件致病性疾病发病率会明显上升,提示需要增强防控工作的针对性。

The heavy rainfalls have hit several provinces in China during this summer. The floods had caused about 150 000 ruminants, 660 000 pigs and 29.96 million poultries to die, which led a direct economic loss of more than Y5.3 billion. Given the high temperature and high humidity in the near future, it is predicted that the epidemic risks of some major animal diseases such as foot and mouth disease, highly pathogenic avian influenza and classical swine fever, et al, are very low because of the compulsory vaccination policy in China, while the endemic risks for some natural focus diseases and conditional pathogenic diseases, such as anthrax, schistosomiasis, streptococcus disease, leptospirosis and dysentery will be growing relatively. It is suggested that some targeted prevention and control measures, such as bio-treatment of dead animals, prophylactic therapy by farms, et al, need to be strengthened in the flooded regions.
