摘　　要：目的调查甘肃省陇南市虫媒传染病在"5.12"地震前后的发病情况,分析地震后虫媒消杀对虫媒传染病的影响。方法收集陇南市2005-2008年流行性乙型脑炎(乙脑)和疟疾发病例数,2005-2009年黑热病的发病例数,计算发病率,分析地震前后虫媒传染病流行病学特点。结果 2005-2008年陇南市共报告乙脑164例,年平均发病率为1.20/10万,2008年乙脑发病率与2005-2007年比较差异无统计学意义(P≥0.05);2005-2009年报告黑热病501例,年发病率为3.68/10万;其发病率男性高于女性(P<0.001);2008年黑热病发病率与2007和2009年比较差异无统计学意义(P≥0.05)。2005-2008年报告疟疾7例,年发病率为0.06/10万。武都区和文县是陇南地区虫媒传染病的主要流行区。结论乙脑和黑热病是陇南市常见虫媒传染病;地震后虫媒传染病发病率未上升,可能与地震后的虫媒消杀工作有密切关系。Objective To investigate the incidence of insect-borne diseases before and after the May 12 Earthquake in Longnan, Gansu province, and to analyze role of disinfection on insect-borne diseases after the earthquake. Methods From 2005 to 2009, data on Japanese encephalitis （JE）, kala-azar and malaria in the area were collected to determine the incidence and analyze the epidemiological characteristics of the insect-borne diseases before and after the earthquake. Results From 2005 to 2008, a total of 164 JE cases were reported with an average incidence rate of 1.20/105. No significant difference between the JE incidence in 2008 and that from 2005 to 2007 （P≥0.05）. From 2005 to 2009, 501 kala-azar cases were reported with an annual incidence rate of 3.68/10^5. More cases were observed in men than in women （P〈0.001）. No significant difference was noted between the incidence in 2009 and incidences in 2007 and 2009 （P〉~O.05）. From 2005 to 2008, seven cases of malaria were reported with an annual incidence rate of 0.06/105. Wudu district and Wenxian county were worst affected by insect-borne diseases. Conclusion JE and kala- azar were historically common insect- borne infectious diseases in Longnan. After the earthquake, the incidence of these diseases did not increase compared to the previous years. The reason may be closely related to insect disinfection work after the earthquake.
