目的调查分析清远市连山少数民族地区阿米巴痢疾的流行病学特征,为制定阿米巴痢疾的预防和治疗对策提供理论参考。方法选取我院2012年9月至2013年8月收治的576例腹泻患者,采用病原学检查联合血清阿米巴抗体,ELISA法检测确诊阿米巴痢疾,并对阿米巴痢疾的流行病学特征进行调查。结果粪便病原菌镜检和血清ELISA检测确诊阿米巴痢疾患者73例,感染率为12.67%。0~6岁儿童患病比率为68.49%,明显高于其他年龄段,差异具有统计学意义(P<0.05);夏秋季节患病比率为75.34%,冬春季节病比率为24.66%,差异具有统计学意义(P<0.05);阿米巴痢疾患者所处生活环境卫生状况较差,且存在不良个人饮食卫生习惯,外界环境有利于阿米巴原虫包囊和滋养体的传播。结论广东省连山少数民族地区阿米巴痢疾的发病人群主要为儿童,且夏秋季节发病率明显较冬春季节升高,较差的环境卫生状况和不良的个人饮食卫生习惯是促进阿米巴原虫广泛传播的重要原因。
Objective To investigate the epidemiological characteristics of amoebic dysentery in Lianshan ethnic minority areas of Qingyuan and to provide theoretical reference for the prevention and treatment of amebic dysentery. Methods A total of 576 cases of diarrhea admitted to our hospital from September 2012 to August 2013 were enrolled in this study. The etiological agents and serum amoebic antibodies were tested. The diagnosis of amoebic dysentery was detected by ELISA. The epidemiology of amoebic dysentery Features to investigate. Results Stool pathogen microscopy and serum ELISA test confirmed 73 cases of amoebic dysentery patients, the infection rate was 12.67%. The prevalence rate of children aged 0-6 years was 68.49%, which was significantly higher than that of other age groups (P <0.05). The prevalence rate in summer and autumn was 75.34%, and the rate of disease in winter and spring was 24.66% Statistical significance (P <0.05). The living environment health status of patients with amoebic dysentery was poor, and there were bad personal diet health habits, the external environment is conducive to the spread of amoeba cysts and trophozoites. Conclusions The incidence of amebic dysentery in Lianshan Minority Areas in Guangdong Province is mainly children, and the incidence rate in summer and autumn is obviously higher than that in winter and spring. The poor sanitation and poor personal hygiene habits are the mechanisms that promote amoebic An important reason for the widespread transmission of protozoa.
