【摘要】 目的通过疟疾病例个案调查流行病学分析,了解控制本地疟疾流行后的病例分布情况,分析来自高疟区的疟疾病例对本地居民疟疾发病的关系,为制定防治对策提供依据。方法选择1998～2006年以来,填写完善的疟疾个案调查表,按时间、地区、人群分布、来自高疟区和低疟区的疟疾病例、本地感染病例统计,分析输入病例与本地疟疾发病的关系。结果1998～2006年共501例,本地感染病例295例,占58.88%,输入病例206例,占41.12%。一年四季均有病例发生,但5～9月病例最多占63.47%。男性占75.65%,女性占24.35%,男:女为3.11:1。发病年龄20～39岁组最多,占49.70%,其次是40～59岁年龄组,占33.13%,<20岁和>60岁组最少,20～39岁组显著高于其他年龄组(p<0.05)。职业以农民最多,占87.03%。来自高疟区疟疾发病人数与本地疟疾发病率呈正相关,显示来高疟区的疟疾病例对本地居民疟疾发病有影响(p<0.005),来自低疟区外来人员疟疾发病人数与本地居民疟疾发病率的关系也呈正相关,但没有统计学意义(p>0.05)。结论本地疟疾疫情趋于稳定,年发病率维持在较低水平,本地感染病例高度分散。发病高峰季节依然存在。发病以青中年男性农民为主。来高疟区的疟疾病例对本地居民疟疾发病有影响,应加强监测和流动人员疟疾管理。更多还原

【Abstract】 Objective To know the distribution of controlled local malaria and analysis the relationship between the malaria in hyper-endemic areas and the incidence of local malaria.Methods The malaria cases were selected in 1998-2006.the cases were classified by time,areas,population distribution,origin of case to analyze the relationship between imported case and incidence of local malaria.Results 501 cases were reported in 1998-2006. The local cases were 58.88%and imported cases were 41.12%.The cases were found in total year.The cases of May-Sep were up to 63.47%.The ratio of male and female was 3.11:1. The age of high incidence was 20 to 39 years old and the cases were 49.70%,secondly 40 to 59 years old(33.13%),less than 20 and more than 60 years old were minimum.The cases of 20-39 years old were significantly higher than other years old(p<0.05).The large occupation was farmer(87.03%).There was a significantly positive relationship between cases in hyper-endemic areas and incidence rate of local malaria(p<0.005).The relationship showed that the cases from hyper-endemic areas impacted local malaria incidence.There was also a positive relationship between cases in hypo-endemic areas and incidence rate of local malaria,but there was no significance(p>0.05).Conclusions The local malaria situation was steady.The incidence rate of years was a lower level.The local cases were very dispersive. The peak time of incidence existed all the time.The mostly cases were the male farmer of 20- 39 years old.The cases from hyper-endemic areas impacted local malaria incidence.The malaria monitoring and floating populations managing should be strengthened.更多还原
