摘要:

为分析2014—2018年南昌市疟疾疫情及其流行病学特征,为该市制定合理的疟疾防控策略提供参考依据,从国家传染病报告信息管理系统和南昌市疟疾疫情报表及流行病个案调查表中收集2014—2018年南昌市疟疾病例及流行病学资料,分析疟疾疫情及流行特征。运用ArcGIS10.1软件分析疟疾病例的空间分布。结果显示,2014—2018年南昌市共报告疟疾病例114例,全部为境外输入性病例。其中从非洲国家输入110例(96.49%),亚洲国家3例(2.63%),大洋洲国家1例(0.88%);疟原虫虫种以恶性疟原虫(65例,57.02%)和间日疟原虫(30例,26.32%)为主;各月均有病例报告,发病季节不明显。男性病例107例(93.86%),女性病例7例(6.14%),男女性别比为15.3 ∶ 1;发病平均年龄为39.81岁。111例(97.37%)疟疾病例集中在20~39岁、40~59岁两个年龄组。职业以境外务工人员(工人44例,38.59%;农民37例,32.46%)为主。从发病到确诊的中位时间为3 d。无复发、再燃、死亡及输入性继发病例发生。进贤县、青山湖区、新建区为南昌市疟疾报告病例数前3的县(区)。ArcGIS10.1软件所制热点图显示,南昌市区和进贤县为点病例集中地区。提示南昌市做好输入性疟疾防控是今后工作的重点,进贤县为重点县。

Abstract:

To analyze malaria situation and epidemiological characteristics in Nanchang from 2014 to 2018, and to provide scientific reference for formulation of a rational malaria control strategy in the city, the information of malaria cases and associated epidemiological data of Nanchang City from 2014 to 2018 were collected from the National Infectious Disease Report Information Management System and the Nanchang Malaria Epidemic Information Sheet and Epidemic Case Survey Form. The ArcGIS 10.1 software was used to analyze the spatial distribution of malaria cases. From 2014 to 2018, a total of 114 malaria cases were reported in Nanchang, all of them were imported cases from countries outside of China. Among them, 110 cases (96.49%) were imported from African countries, 3 cases (2.63%) from Asian countries, and 1 case (0.88%) from an Oceania country.Plasmodium infection was predominated by P. falciparum (65 cases, 57.02%) and P. vivax (30 cases, 26.32%); the cases were reported throughout the months, with no obvious seasonal changes. The malaria cases comprised 107 males (93.86%) and 7 females (6.14%), with male-to-female ratio of 15.3: 1; and the average age of the disease occurrence was 39.81 years. In addition, 111 of the cases (97.37%) were distributed in the age groups of 20-39 and 40-59. The occupation distribution were predominated by workers (44, 38.59%) and farmers (37, 32.46%). The median time from onset to etiological diagnosis was 3 days. No recurrence, re-ignition, death, and imported secondary cases occurred. Jinxian County, Qingshan Lake District, and Xinjian District were the top three counties in Nanchang City in terms of reported malaria cases. ArcGIS10.1 hotspot map showed that Nanchang urban area and Jinxian County were two concentrated spots. These results suggest that prevention and control of imported malaria is the key point of future work in Nanchang City, with Jinxian County as a particular key site.
