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 zoonotic diseases in Longnan, Gansu Province before and after the May 12 earthquake and analyze the impact of zoonosis on zoonotic diseases after earthquakes. Methods The incidence of Japanese encephalitis (JE) and malaria in 2005-2008 and the incidence of kala-azar in 2005-2009 in Longnan were collected to calculate the incidence and epidemiological characteristics of the zoonotic infection before and after the earthquake. Results A total of 164 JE cases were reported in Longnan from 2005 to 2008, with an average annual incidence of 1.20 / 100 000. There was no significant difference in the incidence of JE between 2008 and 2005 (P> 0.05). 2005-2009 The annual reports of kala-azar were 501 cases, the annual incidence rate was 3.68 / 100000; the incidence of males was higher than that of females (P <0.001). There was no significant difference in the incidence of kala-azar between 2008 and 2007 and 2009 (P≥0.05). Seven malaria cases were reported in 2005-2008, with an annual incidence of 0.06 / 100,000. Wudu District and Wen County is the main epidemic area of Longdong area insect-borne diseases. Conclusion Encephalitis and kala-azar is a common zoonotic disease in Longnan City. The incidence of zoonotic diseases does not increase after the earthquake, which may be closely related to the zoonosis after the earthquake.
