摘要:

分析2009-2018年抚顺市输入性疟疾流行病学特征,为制定防控策略和措施提供科学依据。收集2009-2018年抚顺市疟疾疫情资料及疟疾病例个案调查资料,采用SPSS 17.0统计学软件分析疫情概况、感染来源国、地区分布、性别分布、年龄分布、职业分布、月份分布、病例诊断情况和传播媒介。结果显示,2009-2018年抚顺市共报告输入性疟疾病例33例,均为实验室确诊病例,其中恶性疟29例(87.9%)、间日疟2例(6.1%)、未分型疟疾2例(6.1%)。所有病例均为境外输入性病例,其中31例(93.9%)由非洲输入,主要来自安哥拉(12例);2例(6.1%)由亚洲输入,分别来自巴基斯坦(1例)和马来西亚(1例)。抚顺市7个县(区)中,新宾县病例数最多(14例),抚顺县无疟疾病例报告。病例以男性为主(29例,87.9%),女性病例4例(12.1%)。年龄最小的病例是24岁,年龄最大的病例是58岁,40~49岁人群病例数较多(15例,45.5%)。职业分布中,病例以农民为主,有12例(36.4%)。月份分布中,春、夏、秋季的病例数均为8例(24.2%),冬季为9例(27.3%),发病季节不明显。县、市、省级卫生医疗机构的首诊符合率分别为1/6、12/14和13/13,差异有统计学意义(P < 0.01)。发病-首诊的最长时间是51 d,最短时间是1 d,平均时间是5 d;首诊-确诊的最长时间是31 d,最短时间是1 d,平均时间是2 d;发病-确诊的最长时间是57 d,最短时间是1 d,平均时间是8 d。抚顺市区未发现传播媒介中华按蚊;县区中华按蚊主要分布在牲畜棚,其按蚊密度与居民区、公园、医院和农户等地的差异有统计学意义(P < 0.01)。输入性疟疾仍是抚顺市的公共卫生问题。县级卫生医疗机构的疟疾诊断能力较低,需加强疟疾诊治技能培训。

Abstract:

To analyze the epidemiological characteristics of imported malaria in Fushun City so as to provide scientific basis for the development of prevention and control strategies and measures, the data of imported malaria cases in Fushun were collected from 2009 to 2018, the epidemiological information including the source of infection, the distribution of cases in different regions, gender, age, occupations and seasons, diagnosis and transmission vector was analyzed using SPSS 17.0 software. The results showed that total 33 cases of imported malaria were reported in Fushun from 2009-2018. All of them were laboratory confirmed cases including 29 cases of falciparum malaria(87.9%), 2 cases of vivax malaria(6.1%), and 2 undetermined malaria(6.1%). All cases were imported from overseas, 31 cases of them(93.9%) were from Africa, mainly from Angola(12 cases). Two cases (6.1%) were imported from Asia, in particular 1 case from Pakistan and another one from Malaysia. The imported malaria cases have been identified in 7 counties or districts of Fushun City except for Fushun County. Xinbin County owned the highest number of the cases(14 cases). More male patients(87.9%, 29/33) than females(12.1%, 4/33) have been identified with significant difference(P < 0.05). The youngest age is 24 years old, the oldest age is 58 years old. Most of the cases happened within the age between 40 to 49(45.5%, 15/33). Among the occupational distribution, most of the cases were farmers(36.4%, 12/33). There was no significant seasonal distribution for the case onset including 8 cases in spring, summer and autumn(each 24.2%), and 9 cases in winter(27.3%). The rate of correct diagnosis at the first medication at county, city and provincial level facilities was 1/6, 12/14 and 13/13, respectively, and the difference was statistically significant (P < 0.01). The longest time from disease onset to the first seeking medication was 51 days, the shortest was 1 day and the median time was 5 days. The time from the first medication to the confirmed diagnosis varied from 1 day to 31 days with median time of 2 days. The time from the disease onset to the confirmed diagnosis varied from 1-57 days with the median time of 8 days. There was no malaria vector mosquito Anopheles sinnensis found in Fushun City urban area, but found in suburban counties, mainly distributing in livestock sheds. The density of An. sinnensiswas significantly different from residential areas to parks, hospitals and farmer houses (P < 0.01). The imported malaria is still a public health problem in Fushun City. The malaria diagnostic rate in county health medical institutions was low and more training for malaria diagnosis and treatment is needed.
