目的了解广西2006年人感染猪链球菌病疫情的流行病学特点,为制订防制对策提供依据。方法对报告的6例人感染猪链球菌病病例进行个案调查、标本细菌培养和基因检测,对所收集的资料进行数据录入和流行病学分析。结果6例病例均为中老年男性,以肉品加工从业人员和农民为主,地区分布分散,以夏秋季节为高发,传播途径与直接接触猪肉有关,5例(83.33%)有划破手或手上有伤口,66.67%的病例无法追溯到可疑猪肉的来源。临床分型脑膜脑炎型和中毒休克型各3例,主要临床表现为发热、头痛、头晕、畏寒、神志不清、颈项强直、皮肤瘀点瘀斑、四肢酸痛和休克等,大部分病例有血常规WBC和中性粒细胞比例增高,脑膜脑炎型病例脑脊液呈化脓性改变,病死率33.33%,后遗症发生率50.00%。流行原因主要包括农民由于经济困难私宰病死猪,有关部门对猪肉上市流通的监管力度不够、农民及猪肉销售人员在接触猪肉时防护意识不足等。经采取一系列综合性措施每起人间疫情均得到了有效控制。结论广西有效控制该病关键在于畜间疫情的控制、猪肉检疫、流通的监管以及加强农业部门与卫生部门的有效沟通。
Objective To understand the epidemiological characteristics of human swine streptococcal disease in Guangxi in 2006 and provide the basis for the development of control strategies. Methods Six case reports of human case of Streptococcus suis were reported. Bacterial culture and gene test were performed. Data were collected and epidemiological analysis was performed on the collected data. Results The 6 cases were all middle-aged and old men. Mainly engaged in meat processing workers and peasants, the area was scattered and distributed in summer and autumn. The route of transmission was directly related to pork. Five cases (83.33%) had broken hands or There are wounds in hand, 66.67% of the cases can not be traced back to the source of suspicious pork. The clinical classification of meningoencephalitis and poisoning shock in 3 cases, the main clinical manifestations of fever, headache, dizziness, chills, confusion, neck stiffness, ecchymosis, limb pain and shock, most cases Blood WBC and neutrophils increased the proportion of cases of cerebrospinal fluid cerebrospinal fluid showed purulent changes, the case fatality rate was 33.33%, the incidence of sequelae 50.00%. The main causes of epidemics include peasants’ slaughter of dead pigs due to economic difficulties, inadequate supervision by the relevant authorities on the listing and circulation of pork, and insufficient awareness of protection by peasants and pork salespersons when they come into contact with pork. A series of comprehensive measures have been adopted to effectively control every human epidemic. Conclusion The key to effectively control this disease in Guangxi lies in the control of livestock epidemic, the inspection and quarantine of pork, the regulation of circulation and the effective communication between the agriculture department and the health department.
