疟区发热病人易患疟疾的危险因素分析

Analysis of risk factors assoicated with malaria infection in feverishe patients in malaria endemic areas

目的分析疟区发热病人易患疟疾的危险因素,为早期从发热病人中筛检血检对象或服药对象提供借鉴。方法以《发热病人情况登记表》在疟疾传播期收集研究现场发热病人流行病学特征(年龄、性别、发病与就诊日期间隔、家属四邻近期疟疾情况等),对其采血涂制标准血片进行镜检。计算机录入资料、建立数据库,以SPSS软件进行Logistic回归分析。结果共收集发热病人1 508例,其中疟疾病人241例。回归分析显示,年龄、就诊时间间隔、蚊帐使用情况、露宿、家属四邻近期有疟疾病人、休止期服药与发热病人患疟疾有显著相关。结论发热病人中1d内就诊、没有防蚊措施、有露宿习惯、其家属四邻近期患疟疾、未进行休止期服药者,其感染疟疾的可能性将大大增加,可以考虑作为血检对象或服药对象。

Objective To analyze the risk factors associated with malaria infection in feverish patients in malaria endemic areas and provide evidence for early ddiagnosis and treatment of malaria patients.Methods ＂Registration form for patients with fever＂ was desinged and the epidemniological charisteristics of feverishe patients including age,gender,time lag before seeing a doctor etc.were surveyed on the spot during malaraia prevalent period.The blood smeas collected were microscopically exmamined and the data were input into computer and analyzed with SPSS software.Results Totally 1 508 samples from feverish patients were collected and 241 malaria patients were identified.The results of logistic regreession analysis showed that age,time lage before seeing a doctor,use of bednet,sleeping outside,malaria caess in neighbouring families,drug prophylaxis during transmission resting stage were the frisk factors significnatly correlated with malaria infection.Conclusion There are a number of risk factors associated with malaira infection in feverish patients and those without seeing a doctor within a day after having a fever,without use bednets,sleeping outside or without adminisstration of antimalarials for prophylaxis,etc,are the target for blood examination and drug prophylaxis.
