目的了解深圳市重点人群肝吸虫病感染状况并探讨感染危险因素,为制定肝吸虫病防治对策提供依据。方法对2008年5月～2009年5月来诊的肝吸虫病症状可疑、血液嗜酸性粒细胞增高、有生食淡水鱼虾习惯的重点人群进行肝吸虫病血清学检测和相关知识行为学调查。结果共调查1382名6～65岁重点人群,检出肝吸虫IgG抗体阳性373人(26.98%)。男性的感染率为27.89%(260/932),女性感染率为25.11%(113/240),男女性别间比较无统计学差异。不同年龄组人群感染率不同,最高感染率的年龄组分布在31～40岁.知识行为学调查显示,59%的被调查者不了解肝吸虫病及其传播途径,68%的被调查者每月至少吃1次淡水生鱼,11%的家庭生熟刀具未严格区分。结论深圳市重点人群肝吸虫病感染阳性率高于一般人群,加强重点人群的监测和干预对于肝吸虫病的预防和控制有着重要的意义。
Objective To understand the prevalence of hepatic flukes in key populations of Shenzhen and to explore the risk factors for infection, and to provide evidence for the prevention and treatment of. Methods From May 2008 to May 2009, patients with clinically diagnosed hepatic trilobitism were investigated for serological detection and related knowledge-based behavioral tests on the prevalence of hepatic demersitosis, with suspicious symptoms of hepatic trematosis, elevated blood eosinophils and the prevalence of freshwater freshwater fish and shrimp. Results A total of 1382 key population from 6 to 65 years old were investigated. 373 (26.98%) were positive for IgG antibodies against hepatic dengue. The infection rate of men was 27.89% (260/932) and the infection rate of women was 25.11% (113/240). There was no significant difference between men and women. The infection rates of different age groups were different, the highest infection rate of the age group distribution in the age of 31 to 40. Knowledge behavior survey showed that 59% of the respondents do not understand the history of hepaticosis and its transmission, 68% of the respondents each Eat freshwater fish at least once a month, 11% of the family life and cooked knives are not strictly distinguished. Conclusions The positive rate of hepatic flukes in Shenzhen key population is higher than that in the general population. It is of great significance to strengthen the monitoring and intervention of key populations for the prevention and control of.
