目的 了解温州市登革热和疟疾等输入性虫媒传染病发病情况,为输入性传染病防控提供科学依据。方法 对2004－2012年登革热和疟疾疫情进行流行病学分析,收集和分析登革热及疟疾监测资料。结果 温州市累计报告输入性登革热病例11例,其中男性4例,女性7例。以孟加拉国和新加坡输入为主(8/11);发病以6－11月为主,占81.82%。2010－2012年布雷图指数分别为14.65、18.43和16.98,6月布雷图指数最高。2004－2012年累计报告疟疾病例322例,其中间日疟242例,恶性疟71例,混合感染9例。疟疾病例中315例为输入性病例,其中境外输入占34.29%,境内输入占65.71%。血检“三热”患者157 500例,感染率为0.20%。结论 温州市存在登革热和疟疾输入风险及引起本地暴发的危险因素,应加强监测,采取针对性的防控措施,防止登革热和疟疾等输入性传染病暴发流行。

Objective To investigate the incidence of imported vector borne diseases including dengue and malaria in Wenzhou, Zhejiang province, China and to provide a scientific basis for the prevention and control of imported infectious diseases. Methods The epidemic situation of dengue and malaria from 2004 to 2012 was subjected to epidemiological analysis, and the surveillance data of dengue and malaria were collected and analyzed. Results A total of 11 cases of imported dengue were reported from 2004 to 2012 in Wenzhou, including 4 male cases and 7 female cases. Of all cases, 72.73% were imported from Bangladesh and Singapore, and 81.82% occurred from June to November. The Breteau indices from 2010 to 2012 were 14.65, 18.43, and 16.98, respectively, and the index was the highest in June. A total of 322 cases of malaria were reported from 2004 to 2012 in Wenzhou, accounting for 0.20% of 157 500 patients with three types of fever who underwent blood test. These cases included 242 cases of vivax malaria, 71 cases of falciparum malaria, and 9 cases of mixed infection. Among them, 315 cases were imported, 34.29% from other countries and 65.71% from other regions in China. Conclusion Imported dengue and malaria occurs in Wenzhou, and there are risk factors for local outbreak. Monitoring should be strengthened and specific control measures should be taken to prevent the outbreak of imported vector borne diseases like dengue and malaria.
