摘要
2018年11月19日,江西省新余市在进行疫情排查时,发现一养殖场出现生猪异常死亡情况。为了解生猪异常死亡的病因,分析疫点向外传播疫病的风险,开展了紧急流行病学调查。首先建立病例定义,采集样本进行检测,然后进行座谈和实地调查。结合临床症状和实验室检测结果,确诊此次暴发为猪传染性胸膜肺炎疫情,袭击率为16.95%(131/773),病死率为63.36%(83/131)。调查认为,本次疫情暴发的主要原因可能是不同来源的猪混群饲养以及天气寒冷潮湿时较差的饲养管理,人员和车辆的流动也引起了一定的疫情扩散风险。经注射氟苯尼考和复方磺胺,场区内戊二醛葵甲臭溶液喷洒消毒,疫情得到了控制。
On November 19,2018,abnormal deaths of pigs were reported in Xinyu City of Jiangxi Province during the investigation. In order to find out the main causes and analyze the risk of disease transmission from epidemic focus,an emergency epidemiological investigation was carried out. Firstly,the case definition was established and the samples were collected. Then by approaches of discussion,field survey and questionnaire, the investigation was launched. Based on results of clinical symptoms and laboratory detection,the cause of the outbreak was finally confirmed as porcine contagious pleuropneumonia(PCP),the attack rate was 16.95%(131/773) and the mortality was 63.36%(83/131). According to the investigation,the epidemic was mainly caused by the mixing of pigs from different sources,as well as the poor feeding management when the weather was cold and humid. Besides,the flow of people and vehicles also resulted in certain spread risk of the epidemic. After injection of Florfenicol and Compound sulfonamide,and spray and disinfection by the Glutaraldehyde sunflower odor solution in the field,the epidemic was finally controlled.
