摘要
目的分析2014-2021年湖北省输入性卵形疟病例的流行病学特征,为消除疟疾后的风险评估提供科学依据。方法根据国家传染病报告信息管理系统收集2014-2021年湖北省卵形疟病例资料,对病例的地区、时间和人群分布,感染来源地及就诊情况等建立数据库,并进行统计分析。结果2014-2021年,湖北省共网报输入性疟疾病例840例,其中输入性卵形疟病例115例占13.96%(115/840)。全省报告卵形疟病例居前5的地市依次为武汉市33例、宜昌市16例、黄石市13例、襄阳市11例和黄冈市7例。12月报告的病例数最多为17例占14.78%(17/115),7月报告的病例数最少为4例占3.48%(4/115)。98.26%(113/115)的输入性卵形疟病例来自非洲22个国家,主要来自刚果金(19例)、尼日利亚(12例)和安哥拉(9例)这3个国家。病例初诊单位主要集中在地市级医疗机构占35.65%(35/115),初诊诊断为疟疾的病例82例,初诊正确率为71.30%(82/115)。全省45.22%的卵形疟病例由地市级医疗机构确诊。结论湖北省2014-2021年均有输入性卵形疟病例报告,感染来源主要来自非洲。病例的初诊和确诊单位主要集中在县级及以上医疗机构。因此,需要持续提升医疗机构的疟疾防治意识和检测能力,特别是针对卵形疟原虫,巩固全省消除疟疾成果。
Objective To understand the epidemic characteristics of imported Plasmodium ovale in Hubei province from 2014 to 2021,and provide the evidence for adjusting the strategies in the post-elimination stage.Methods Data of P.ovale cases in Hubei during 2014-2021 was collected from the National Infectious Disease Surveillance Reporting and Management System and statistically analyzed the distributions of disease,infection source and the experience of seeking medical care,etc.Results 2014 to 2021,a total of 840 malaria cases was reported in Hubei province;115 cases(13.96%,115/840)of them were infected with P.ovale.Malaria cases infected with P.ovale were reported mainly from Wuhan(33 cases),Yichang(16 cases),Huangshi(13 cases),Xiangyang(11 cases)and Huanggang(7 cases).During this period,P.ovale cases were reported all year round;the maximum was 17 cases in December(17/115,14.78%)and the minimun was 4 cases in July(4/115,3.48%).98.26%(113/115)of P.ovale cases were imported from 22 countries of Africa;the top three countries with the high import number were the Democratic Republic of the Congo(19 cases),Nigeria(12 cases)and Angola(9 cases).The first-diagnosis units of cases were mainly concentrated in prefecture-level medical institutions(35/115,35.65%);82 cases were newly diagnosed as malaria cases,and the correct rate of initial diagnosis was 71.30%(82/115).45.22%of malaria ovale cases in the province were diagnosed by prefecture-level medical institutions.Conclusions There were reports of imported malaria ovale cases in Hubei province from 2014 to 2021,and the source of infection was mainly from Africa.The initial diagnosis and confirmation units of cases were mainly concentrated in medical institutions at or above the county level.Therefore,it should be necessary to continue to improve the awareness of malaria prevention and detection capabilities of medical institutions,especially for Plasmodium ovale,to consolidate the achievements of malaria elimination in the province.
