目的了解大连市2011~2013年疟疾流行情况,为疟疾防治工作提供科学依据。方法收集大连市2011~2013年疟疾病例资料,以流行病学的方法分析其特点。结果 2011~2013年共检出疟疾41例,均为输入性病例,平均年检出率为0.212/10万。其发病季节呈全年分布,以11~12月为发病高峰。患者中男性40例,占97.6%;女性1例,占2.4%。多数为海上捕捞工和建筑工,以非洲输入病例为主。所有病例在国内发病后到确诊的间隔时间最长为25d,平均确诊天数为9.8 d。确诊时间与首诊时间间隔最长为15d,平均3.6d。病例中以三级医院确诊病例为主,占95.1%(39/41)。病例中重症病例占12.2%(5/41),其中脑型疟3例,有1例死亡病例。结论输入性疟疾病例是大连市疟疾疫情的特点,必须加强境外输入病例的管理,特别是来自高疟流行区人群的管理、监测与病例管理。
Objective To understand the prevalence of malaria in Dalian from 2011 to 2013 and provide a scientific basis for malaria control. Methods The data of malaria cases in Dalian from 2011 to 2013 were collected and analyzed by epidemiological methods. Results From 2011 to 2013, 41 cases of malaria were detected, all of which were imported. The average annual detection rate was 0.212 / 100000. The incidence of the season was distributed throughout the year, 11 to 12 months for the peak incidence. There were 40 males (97.6%) and 1 females (2.4%). Most are sea-fishers and builders, with the majority of cases being imported from Africa. All cases in the country after the onset of disease to the diagnosis of the longest interval of 25d, the average number of days diagnosed as 9.8d. The diagnosis time and the first diagnosis of the longest interval of 15d, an average of 3.6d. Among the three cases, 95.1% (39/41) were diagnosed in tertiary hospitals. Cases of severe cases accounted for 12.2% (5/41), including cerebral malaria in 3 cases, 1 case of death. Conclusion The imported cases of malaria are the characteristics of the malaria epidemic in Dalian.
