Objective To analyze the diagnosis of imported malaria cases in Gansu province from 2011 to 2019, so as to provide a basis for the prevention of re-transmission after elimination of malaria. Methods Malaria cases in Gansu province from 2011 to 2019 were collected and analyzed, through the information management system of infectious disease report and parasitic diseases prevention and control, and the incidence of the disease, the distribution of imported origin, diagnosis methods, diagnosis institutions and diagnosis timeliness were statistically analyzed. Results From 2011 to 2019, 199 imported malaria cases were reported, 149 (97.49%) of which were laboratory confirmed, and five cases were clinically diagnosed, which accounting for 2.51%. P.falciparum and P. vivax accounted for 57.79% (115/199) and 36.18% (72/199), respectively. 56.78% (113/199) of the cases were farmers. Cases were mainly imported from Angola, Chad, Nigeria and other 22 countries in Africa, which accounting for 69.85% (139/199), and the remaining 30.15%(60/199) were imported from Asia, which were mainly imported from Indonesia. Among the 199 cases, the CDCs and the medical institutions diagnosed 22.11% (44/199) and 77.89% (155/199) of the cases respectively. The proportion of cases diagnosed by the CDCs decreased from 50.00% (9/18) in 2011 to 11.11% (2/18) in 2019, while the proportion of cases diagnosed by the medical institutions increased from 50.00% (9/18) in 2011 to 88.89% (16/18) in 2019. Only 6.82% (3/44) of the cases diagnosed by CDCs were at the prefecture-level. The median time from onset to diagnosis of malaria cases was 2 d, of which P. ovale was 3 d as the longest. Conclusion We should continue to improve the diagnostic awareness and level of medical and disease control institutions, to avoid the risk of re-transmission caused by misdiagnosis and missed diagnosis of imported malaria. 摘要:目的 分析 2011—2019 年甘肃省输人性疟疾病例诊断情况, 为制定消除疟疾后防止再传播工作提供依据。 方法 通过中国疾病预防控制中心信息管理系统和寄生虫病防治信息管理系统, 收集整理 2011—2019 年甘肃省疟疾 病例信息, 对其发病情况、输人地分布、诊断方式、诊断机构、诊断及时性等情况进行统计描述与分析。 结果 2011—2019 年全省共报告国外输人性疟疾病例199 例, 194 例为实验室确诊病例 (97.49%), 5 例为临床诊断病例 (2.51%)。疟 疾分型以恶性疟和间日疟为主, 分别占 57.79% (115/199) 和 36.18% (72/199)。所有病例职业以农民最多, 占 56.78% (113/199)。病例输人地主要分布于非洲的安哥拉、乍得、尼日利亚等 22 个国家, 占 69.85% (139/199), 剩余 30.15% (60/199) 的病例输人地为以印度尼西亚为主的亚洲。199 例病例中, 疾控机构诊断病例占 22.11% (44/199), 医疗机构诊断 病例占 77.89% (155/199)。疾控机构病例诊断比例由 2011 年 50.00% (9/18) 降至 2019 年的 11.11% (2/18), 医疗机构诊 断病例比例由 2011 年 50% (9/18) 上升到 2019 年 88.89% (16/18)。疾控机构诊断的病例中市级疾控机构诊断最少, 为 6.82% (3/44)。疟疾病例从发病到确诊时间中位数为 2d, 其中卵形疟病例从发病到确诊时间最长, 中位数为 3d。 结论 继续提高医疗和疾控机构的诊断意识和水平, 避免消除疟疾后因输人性疟疾误诊、漏诊而引起的再传播风险。

Objective To elaborate the epidemic of imported malaria in Jiangsu province from 2015 to 2019, and to prevent the importation and re-transmission of malaria, and we provide information for malaria control and elimination. Methods Data on imported malaria cases in Jiangsu Province from 2015-2019 were collected and sorted through the National Infectious Diseases Information Reporting Management System (IDIRMS) and the Parasitic Diseases Information Reporting Management System (PDIRMS). The incidence and distribution of malaria were described in Jiangsu Province from 2015 to 2019. The distribution of three dimension, diagnostic institutions and diagnostic timeliness of imported malaria cases were described and analyzed. Results From 2015 to 2019, a total of 1 439 cases were reported in Jiangsu Province, of which 1 436 were imported cases, and 3 cases were blood transfusion infection cases. The reported cases were comprised of Plasmodium falciparum (1 075, 74.7%), Plasmodium vivax (63, 4.4%), Plasmodium ovale (233, 16.2%), Plasmodium malariae (65, 4.5%), and mixed infections (3, 0.2%). Imported malaria cases mainly came from Africa (97.5%, 1 400/1 436), Asia (1.9%, 28/1 436), South America and Oceania (0.6%, 8/1 436). The cases were reported from 13 cities in Jiangsu Province. The main imported malaria cases were young men aged 35-<50 years. In January, June and October, more cases were reported than other months. And 83.2% of the cases were diagnosed by medical institutions. The percentage of cases diagnosed by disease control agencies has decreased year by year ( P <0.05). The percentage of patients with more than 9 days time interval between onset and diagnosis in 2019 was significantly lower than that in the previous four years ( P <0.01). Conclusion Malaria epidemic situation in Jiangsu Province has been stable in recent five years. Most malaria cases are imported from abroad, a small part of malaria cases are infected by blood transfusion. The interval between onset and diagnosis is shorter. Prevention of the re-transmisson of imported malaria, improving the efficiency of diagnosis and treatment, and strengthen health education are very important for malaria prevention in Jiangsu Province. 摘要:目的 分析江苏省2015—2019年输人性疟疾疫情流行特征及诊断情况,为防止疟疾输人再传播,巩固消除 疟疾成果提供科学参考。 方法 疟疾疫情资料来自国家传染病监测系统和寄生虫病防治信息管理系统,采用流行病 学研究 方法 ,描述2015—2019年江苏省疟疾发病、感染来源和病例三间分布情况,对输人性疟疾病例的诊断以及发病 到诊断的时间间隔进行分析。 结果 2015—2019年,江苏省共报告1 439例疟疾病例,其中1 436例为境外输人病例,3例为输血感染病例。1 439例疟疾病例中,恶性疟1 075例（占74.7%)、间日疟63例（占4.4%)、卵形疟233例（占 16.2%)、三日疟65例（占4.5%)、同一时间发病的混合感染病例3例（占0.2%)。境外输人性疟疾病例中,1 400例来自非 洲（占97.5%),其他来自亚洲28例（占1.9%),以及南美洲和大洋洲8例（占0.6%)。江苏省13个设区市均有疟疾病例报 告;疟疾病例以35~<50岁男性青壮年居多,每年的1、6和10月出现病例报告髙峰。82.3%的病例由医疗机构诊断,由 疾控机构诊断的病例占比逐年降低( P <0.05)。2019年发病到确诊超过9 d的病人所占比明显低于前四年( P <0.01)。 结论 近5年江苏省疟疾疫情稳定,绝大部分为境外输人性病例,存在少数输血感染;病人就诊到确诊间隔时间有所缩 短。继续做好风险人群健康宣教,提髙医疗机构诊治能力,防止发生境外输人再传播,是今后疟疾防控工作的重点。

Objective To analyze the epidemiological characteristics of imported malaria in Mianyang during the 20092019 period, and we provide scientific basis for the control of imported malaria. Methods The epidemic situation was collected from the infectious disease reporting information system and the epidemiological investigation data of imported malaria during 2009–2019 in Mianyang. The data were analyzed by descriptive epidemiological. Results A total of 169 imported malaria cases were reported during 2009–2019 in Mianyang, all were laboratory confirmed cases, with an average annual incidence rate of 0.43/100 000. There were 64 cases (37.876%) of vivax malaria, 91 cases (53.85%) of falciparum malaria, 5 cases (2.96%) of ovale malaria, 1 case (0.59%) of quartan malaria and 8 cases (4.73%) of mixed infections. Imported cases were reported all the year round, June and July had the most cases, with 22 cases each, accounting for 26.04% of the whole year. There were 10 cases (5.92%) imported from other province in China, 38 cases (22.49%) imported from 6 countries in Asia, 121 cases (71.60%) imported from 24 countries in Africa. Imported malaria cases have been reported in 10 counties. The average age of the cases was (38.45±11.74) years. Malaria cases were majorly young men working as peasant and migrant workers. The average time from symptom appearing to being diagnosed was 4.18 d, 39.05% and 56.21% of the patients were diagnosed in municipal and county medical treatment units, respectively. Conclusion The situation of imported malaria from overseas is still serious in Mianyang. It is important to improve the malaria diagnosis and treatment, and strengthen the health education of migrant workers and their families in order to achieve better prevention and control of imported malaria in the area and put an end to secondary cases. 摘要:目的 分析 2009—2019 年四川省绵阳市输人性疟疾的流行病学特征, 为进一步加强输人性疟疾防治工作提 供科学依据。 方法 通过法定传染病报告信息管理系统, 收集绵阳市 2009—2019 年疟疾病例流行病学资料和病例个 案调査资料。采用描述性流行病学方法对这些资料进行统计学分析。 结果 2009—2019 年绵阳市共有 169 例输人性 疟疾病例, 均为实验室确诊病例, 年均发病率 0.43/10 万。其中间日疟64 例 (37.87%)、恶性疟 91 例(53.85%)、三日疟1 例 (0.59%)、卵型疟 5 例 (2.96%)、混合感染 8 例 (4.73%)。输人性病例全年均有分布, 6 月和 7 月最多, 均为 22 例, 占全年 的26.04%。169例输人性疟疾病例中, 10 例 (5.92%)来自国内其他省份, 38 例 (22.49%)来自亚洲 6 个国家, 121 例 (71.60%)来自非洲 24 个国家。全市10 个县市区均有输人性疟疾病例报告。病例平均年龄 (38.45±11.74) 岁, 主要为男 性青壮年, 职业以农民、工人为主。发病至诊断时间平均为 4.18d, 39.05%、56.21% 的病例分别在县级、市级医疗机构确 诊。 结论 绵阳市输人性疟疾疫情仍然严峻, 应引起高度重视, 需进一步加强输人性疟疾防控;提高医务人员疟疾诊 治能力, 完善疟疾监测体系, 加强对重点地区重点人群尤其是出境人员和高疟区回归人员的健康教育, 防止继发病例 发生。

Objective To collect and analyze the epidemic regularity and distribution characteristics of imported malaria in Baise from 2009 to 2019, and we provide scientific basis for Baise to formulate appropriate prevention and control strategies and measures after realizing the goal of eliminating malaria. Methods The results of imported malaria surveillance from abroad in Baise from 2009 to 2019 were collected, analyzed and summarized. Results From 2009 to 2019, a total of 50 malaria cases were reported in Baise, of which 49 cases (98.00%) were blood positive, and 1 case (2.00%) was clinically diagnosed; The distribution of malaria species in blood test positive cases: 14 cases (28.57%) were vivax, 34 cases (69.39%) were falciparum, there was 1 case (2.04%) of ovum type malaria. No mixed infection and malariae malaria cases were found. The largest regional distribution of imported cases was in Longlin Various Nationalities Autonomous County (25 cases, 50.00%); all cases were male; except for a peak in January 2012, there was no significant seasonal distribution of cases overall; The average time from return to onset was 7.2 days, and the average time from onset to diagnosis was 7.8 days; 32 cases (64.00%) were reported by county CDC; Two cases of critical illness occurred in 2016 and 2018 respectively, and no fatal cases occurred. After the last local malaria case was reported in 2008, all malaria cases have been reported as imported malaria cases so far. In 2016, all cases reached the assessment criteria of malaria elimination at the district level in Guangxi, imported malaria cases have not resulted in secondary cases in the urban area of Baise. Conclusion The Malaria Control Strategy and comprehensive anti-malaria measures adopted in Baise are effective under the current situation of malaria control with no local cases. In the future, the measures of aetiological surveillance will be further implemented, health education and training for malaria control will be carried out, and the monitoring of the migrating population will be strengthened. 摘要:目的 分析2009—2019年百色市境外输人性疟疾疫情流行规律和分布特征,为百色市实现消除疟疾的目标 后制定适合的防控策略和措施提供科学依据。 方法 收集及整理2009—2019年百色市境外输人性疟疾疫情监测结果 并对数据进行分析和总结。 结果 2009—2019年百色市累计报告疟疾病例50例,其中49例为血检阳性病例 (98.00%),1例为临床诊断病例（2.00%)。血检阳性病例中虫种分布情况为：间日疟14例（28.57%),恶性疟34例 (69.39%),卵型疟1例(2.04%),无混合感染病例和三日疟病例的发现。输人性病例地区分布以隆林县最多(25例, 50.00%)性别全部为男性；除了 2012年1月份有一个高峰期外,总体上病例无明显的季节分布;从回国至发病平均时 间为7.2 d,从发病至确诊的平均时间为7.8 d;县级疾控中心报告32例（64.00%);危重症病例2例,分别于2016年及 2018年出现,无因重症而死亡的病例出现。2008年报告最后一例本地感染疟疾病例后,至今疟疾病例报告全部为境外 输人性,2016年达到广西壮族自治区消除疟疾考核评估的标准,输人性疟疾病例未在百色市辖区内引起继发性病例。 结论 百色市在没有本地病例的疟疾防治现状下采取的疟疾防控策略和综合抗疟措施有效。今后应进一步落实病原 学监测的措施,开展疟疾防治的健康教育宣传和培训以及加强对流动人口的监测。

Objective To analyze the medical treatment and diagnosis of imported malaria cases in Anhui Province, and we provide a basis for the development of technical measures to block the retransmission of imported malaria after the elimination of malaria. Methods Data on imported malaria cases in Anhui Province from 2016 to 2019 were collected through the National Infectious Diseases Information Reporting Management System (IDIRMS) and the Parasitic Diseases Information Reporting Management System (PDIRMS). The medical institution, diagnosis institutions and diagnosis timeliness of imported malaria cases were described and analyzed by chi-square test and rank-sum test. Results A total of 421 cases of imported malaria were reported in Anhui Province from 2016 to 2019, including four species of malaria, and 3 deaths. 86.5% (364/421) of the cases first visited in medical institutions, and 70.1% (295/421) of the cases were correctly diagnosed as malaria at the first visit. The correct diagnosed rate of initial visit by CDCs (100.0%) was higher than that of medical institutions (66.8%)( P 0.05); the difference in the ratio of the number of days between the first visit and the diagnosis between the years was statistically significant ( P 0.05), however, the initial diagnosis-diagnosis time of severe falciparum malaria cases [3 (1, 5)] was longer than that of mild cases [1 (1, 3)], and the difference was statistically significant ( P 0.05);各年份初诊-确诊时间间隔天数构成比差异有统计学意义( P 0.05),重症和轻症恶性疟病例初诊-确诊时间中位数( P 25 , P 75 )分别为3(1,5) d和1(1,3) d,差异有统 计学意义( P <0.05)。3例死亡病例在初诊时未被确诊,于发病后≥3 d确诊。 结论 安徽省输人性病例的初诊和确诊单 位主要在医疗机构,尤其是县级以上医疗机构,需继续提高医疗机构的疟疾诊断水平,并减少重症病例的发生,同时加 强健康教育以提高病例及时就诊意识。

Objective Through analyzing the epidemiological characteristics and case management of imported malaria in Chongqing, to discover the weakness of malaria control program, and we provide technical advice for the adjustment of malaria prevention and control strategies. Methods Malaria cases information reported in Chongqing were collected from National Parasitic Diseases Information Management System on January 1, 2016 – December 31, 2019. Descriptive statistical analysis was used to study the distribution characteristics of cases in time, spaces and crowds. The interval days from "case onset" to "cases been diagnosed" were compared according to the annual and illness degree. Results There were a total of 131 imported malaria cases reported in Chongqing from 1 Jan 2016 to 31 Dec 2019, including 102 falciparum malaria, 16 vivax malaria, 10 ovale malaria, 2 mixed infection, and 1 quartan malaria. Most of the cases were male construction workers infected in Africa. There were 28 counties (districts) reported cases, among them, 30 cases were reported in Yuzhong District, 27 in Shapingba District, and each 9 cases were reported in Wanzhou District and Yubei District. of which 4 districts reported 57.30% of the total. County level medical institutions was the first choice for 37.40% of the cases when they began feeling sick, and the proportion of cases got malaria diagnosis in county level medical institutions was 63.27% (31/49). The average interval days of the cases from "malaria onset" to "first visit to the hospital" was 3.81 days (median= 1 days), and from "first visit to the hospital" to "got malaria diagnosed" was 4.65 days (median=2 days). The proportion of hospitalized cases was 58.02%. The interval days of hospitalized cases from "first visit to the hospital" to "got malaria diagnosed" was significantly longer than the interval days of general cases ( P <0.01). Conclusion The malaria cases in Chonqing were mostly imported from Africa, of which the interval days from from "malaria onset" to "got malaria diagnosed" was long within a high proportion of hospitalized cases. The efficient measures to reduce the incidence of severe malaria and mortality were: to strengthen malaria health education among the oversea workers, carry out technical training courses on malaria diagnosis and treatment at the primary medical institutions, and establish one specialized malaria medical treatment hospital in each county in Chongqing. 摘要:目的 分析重庆市 2016—2019 年输人性疟疾疫情的流行病学特征和病例管理情况, 评估重庆市疟疾的防 控工作薄弱环节, 为重庆市消除疟疾防控措施的调整提供依据。 方法 从国家寄生虫病信息管理系统收集 2016 年 1 月 1 日一 2019 年 12 月 31 日重庆市辖区内报告的疟疾病例个案信息, 对病例在时间、空间、人群的分布进行描述性统计 分析, 对病例在发病到初诊和初诊到确诊的间隔时间按年度和病情程度进行比较。 结果 共报告确诊境外输人疟疾 131 例, 其中恶性疟 102 例, 间日疟 16 例, 卵形疟 10 例, 混合感染 2 例, 三日疟 1 例。病例以在非洲地区务工的青壮年男 性为主。有 28 个区县有病例报告, 其中渝中区 30 例, 沙坪坝区 27 例, 万州区和渝北区均报告 9 例, 4 个区县报告病例数 占全部病例的 57.3%。病例初次诊单位主要在县级医疗机构占 37.4%, 其诊断正确率为 63.3%(31/49)。病例从“发病-初诊”和“初诊-确诊”间隔时间的中位数分别为 1 d 和 2d。症状较重住院治疗病例占 58.0%。住院治疗病例从“初诊-确诊”间隔时间高于门诊治疗病例, 差异有统计学意义( P <0.01)。

Objective To analyze the epidemiological characteristics of imported malaria in He´nan Province during the late stage of malaria elimination from 2016 to 2019, so as to provide the evidence based technical and theoretical support for strategies and measures in the post elimination stage. Methods The malaria epidemic data and related case reporting information in He´nan Province from 2016 to 2019 were collected. The epidemic situation, distribution characteristics of cases, source of infection, diagnosis and treatment management and recurrence of vivax malaria cases were analyzed by descriptive epidemiology. Results A total of 769 malaria cases were reported in He´nan Province from 2016 to 2019, all imported from abroad. Among them, 581 cases were falciparum malaria, 107 cases were ovale malaria, 49 cases were vivax malaria, 24 cases were malariae malaria, 1 case was knowlesi malaria, and 7 cases were mixed infection. The imported cases came from 41 countries in three continents, and Africa had the largest number of imported cases (738 cases), accounting for 95.97% of the total number of imported cases. The cases were distributed in 18 provincial cities, involving 149 counties (cities and districts), and showed sporadic distribution. The majority of the patients were male (755 cases, accounting for 98.18%), mainly concentrated in the age group of 30-50 years (496 cases, accounting for 64.50%), and the majority were foreign migrant workers (588 cases, accounting for 76.46%). All cases were reported all year round, without obvious seasonal characteristics. The average time from onset to initial diagnosis, and from initial diagnosis to diagnosis was 2.6 days and 2.7 days respectively. The report rate of 24 hours after diagnosis was 100%, the epidemiological investigation rate within 3 days was 98.18%, and the disposal rate of epidemic spot within 7 days was 96.49%. From 2016 to 2019, 7 P. vivax cases relapsed within 1 year, and 2 of them had a third attack. Conclusion During 2016-2019, there was no local infection in He´nan Province, but the epidemic of imported malaria is still serious. Therefore, the risk of secondary infection and epidemic spread caused by imported malaria can not be ignored. All localities should continue to do a good job in monitoring after the elimination of malaria and adopt targeted measures to prevent re-transmission of malaria and consolidate the achievements of malaria elimination. 摘要:目的 分析2016—2019年河南省输人性疟疾流行病学特征,为消除后阶段的策略和措施提供数据支撑和 理论依据。 方法 收集2016—2019年河南省疟疾疫情数据及相关的病例资料,对疫情概况、病例的分布特征、感染来 源、诊治管理情况及间日疟病例复发情况等进行统计分析。 结果 2016—2019年河南省共报告疟疾病例769例,均由 境外输人。其中恶性疟581例,卵形疟107例,间日疟49例,三日疟24例,诺氏疟1例,混合感染7例。输人病例来源于 3大洲的41个国家,非洲输人最多(738例）,占输人病例总数的95.97%,病例的分布遍及18个省辖市,涉及149个县 (市、区）,并呈散发分布。发病人群男性居多(755例,占98.18%),主要集中在30~50岁年龄段(496例,占64.50%),以 境外务工人员为主(588例,占76.46%)。全年均有病例报告,无明显的季节特征。病例从发病到初诊、从初诊到确诊的 平均时间分别为2.6 d和2.7 d;诊断后24 h报告率为100%,3 d内完成流行病学调査率为98.18%,7 d内疫点处置率为 96.49%。2016—2019年,7例间日疟病例出现复发,复发时间均小于1年,其中2例病例出现二次复发。 结论 2016—2019年,河南省维持

Objective To provide the basis for the surveillance to prevent re-transmission after malaria elimination by analyzing the diagnosis imported malaria cases in Shanxi Province during 2015-2019. Methods Data on imported malaria cases in Shanxi Province from 2015 to 2019 were collected and sorted through the National Infectious Diseases Information Reporting Management System (IDIRMS) and the Parasitic Diseases Information Reporting Management System (PDIRMS). Diagnostic institutions and diagnostic timeliness of imported malaria cases were described and analyzed by chi-square test and rank-sum test. Results A total of 72 imported malaria cases were reported in Shanxi during 2015-2019, all cases were imported from abroad, among which falciparum malaria accounted for 68.1% (49/72), vivax malaria 18.1% (13/72), ovale malaria 8.3% (6/72), malariae malaria 2.8% (2/72), and mixed infection 2.8% (2/72). And all of which were diagnosed with laboratory tests (100.0%). The rate of diagnosis in medical institutions was 95.8% (69/72), while 73.9% (51/69) were diagnosed in provincial medical institutions, 21.7% (15/69) were diagnosed in municipal medical institutions, 4.3% (3/69) of 69 cases diagnosed in medical institutions were diagnosed in county-level medical institutions. The median time from onset to diagnosis of malaria cases was 5 days, in which the median time from onset to first visit was 3 day. There were significant difference in the time both from onset to first visit and first visit to diagnosis ( P <0.05), the interquartile interval of malaria cases was shortened from the longest 10 days in 2017 to the shortest zero days in 2019. Conclusion Medical institutions in Shanxi Province play an important role in malaria case detection and monitoring. We should improve the diagnostic awareness and capabilities of county-level medical institutions, and to play the role of sentinel hospitals in the surveillance of preventing re-transmission after malaria elimination. 摘要:目的 分析山西省2015—2019年输人性疟疾病例诊断情况,为消除疟疾后防止输人再传播的监测工作提 供依据。 方法 通过传染病报告信息管理系统和寄生虫病防治信息管理系统,收集整理2015—2019年山西省疟疾病 例信息,对其诊断机构、诊断及时性等情况采用 χ 2 检验、秩和检验进行统计分析。 结果 2015—2019年全省共报告疟 疾病例72例,均为境外输人性病例,其中恶性疟占68.1%(49/72),间日疟占18.1%(13/72),卵形疟占8.3%(6/72),三日 疟占2.8%(2/72),混合感染2.8%(2/72)。所有病例均为实验室确诊病例,镜检检测率均为100.0%。95.8%(69/72)的病 例在医疗机构诊断,而69例在医疗机构诊断的病例中,73.9%(51/69)在省级医疗机构诊断,21.7%(15/69)在市级医疗 机构诊断,仅4.3%(3/69)在县级医疗机构诊断。疟疾病例从发病-确诊时间中位数为5 d,其中发病-初诊时间中位数 为3 d,发病-初诊和初诊-确诊时间各年份差异均有统计学意义,四分位数间距由2017年最长的10 d缩短为2019年最 短的0 d。 结论 山西省医疗机构在疟疾病例发现和监测中具有重要作用。疟疾病例诊断以省级医疗机构为主,提 示市、县级医疗机构的诊断水平较低。今后要加强市县级医疗机构的培训以提高其疟疾诊断意识和诊断能力。

Objective To analyze the epidemiological characteristics of 258 imported malaria cases of Huai’an city, and we provide scientific basis for improving malaria diagnosis and monitoring capacity, preventing secondary transmission of imported malaria, and consolidating the achievements of malaria elimination work. Methods Descriptive analysis was conducted by collecting the epidemiological survey data, basic situation table of epidemic spot, report of epidemic investigation and medical record data related to malaria diagnosis and treatment in hospital in Huai’an city from 2012 to 2019. Results All the types of malaria were detected in Huai’an city, including 203 cases of falciparum malaria, 4 cases of vivax malaria, 39 cases of ovale malaria, 8 cases of quartan malaria and 4 cases of mixed infection. These cases had a wide range of importing countries (22 countries). There were 255 cases from Africa, 2 cases from Oceania, and 1 case from Southeast Asia, corresponding to the proportion of 98.83%,0.78% and 0.39% respectively. The number of living days abroad ranged from 15 to 2 990 days, and the number of onset times from 0 to 30. Before the Spring Festival, before the wheat harvest and before the autumn harvest were the three peaks of cases returning to China, accounting for 72.48% (187/258). Most of the reported cases are from District Qingjiangpu, which were 109 cases accounting for 42.25%. The young adults aging from 20 to 49 years old account for 83.33% (215 cases). There are 131 cases detected in the group of the migrant workers, accounting for 50.78%. The average time interval from returning home to onset was 9.5 days, and the longest was 634 days. Among them, 93.10% (189/203) of patients with falciparum malaria became ill within 30 days. The average interval between onset and diagnosis of patients was 2 days, and 254 cases were diagnosed within 30 days (98.45%). Conclusion Since 2012, all the reported malaria cases were imported. The health education for personnel shuttling between high malaria areas and screening for malaria among returnees should be strengthened. We should improve the ability of malaria diagnosis and treatment of medical institutions above the county level to review blood tablets. These methods can avoid the death cases and the secondary spread of the imported malaria, and consolidate the achievements in the elimination of the malaria. 摘要: 目的分析淮安市 258 例输人性疟疾病例流行病学特征,为提升疟疾诊治能力和监测响应水平,防止输人性 疟疾的继发传播,巩固消除疟疾工作成果提供科学依据。 方法 收集淮安市 2012—2019 年疟疾病例流行病学个案调 査表、疫点基本情况表、疫点调査与处置报告、医院有关疟疾诊治的病历资料等,对其进行描述性分析。 结果 淮安市 2012—2019 年输人性疟疾 258 例,其中恶性疟 203 例,间日疟 4 例,卵形疟 39 例,三日疟8例,混合感染 4 例。输人地广 泛,涉及 22 个国家,其中非洲 255 例、大洋洲2例和东南亚 1 例,分别占总病例数 98.83%、0.78%和0.39%。国外居住15~2 990 d,期间发病次数0~30次；回国多集中在春节前、麦收前和秋收前三个高峰,占总回国人数72.48%(187/258)。清 江浦区报告病例数最多,为109例,占42.25%;20~<49岁青壮年215例,占总病例数的83.33%;民工131例,占总病例数 的50.78%;回国至发病时间间隔平均为9.5 d,最长为634 d,其中93.10%(189/203)的恶性疟患者在回国后30 d内发病。患者自发病至确诊时间平均为2 d,30 d内确诊254例,占总数的98.45%。 结论 淮安市自2012年以来全市报告的均 是境外输人性疟疾病例,应加强对往返于高疟区人员的健康教育

Objective To analyze the imported malaria epidemic situation of Changsha city from 2015 to 2019, and we provide basis for consolidating the achievements of eliminating malaria and preventing and controlling malaria in the future. Methods Data on malaria cases in Changsha from 2015 to 2019 were collected, and sorted through the National Infectious Diseases Information Reporting Management System (IDIRMS) and the Parasitic Diseases Information Reporting Management System (PDIRMS). The epidemiological features of malaria cases were described, and malaria diagnostic agency, diagnostic timeliness, state of an illness were analyzed by chi-square test and rank-sum test. Results A total of 290 cases of imported malaria were reported in Changsha from 2015 to 2019, all of them were imported from abroad, with imported falciparum malaria accounting for 74.83%; Cases of malaria have been reported and distributed in nine districts (counties and cities) of Changsha. The current address is 151 cases in this city and 139 cases in other places. The majority of malaria patients are young and middle-aged male workers. The number of cases diagnosed and treated in municipal medical institutions was the highest, and the diagnosis rate in provincial medical institutions was the highest. There was no statistically significant difference in the interval between initial diagnosis and diagnosis in provincial, municipal and county medical institutions ( H =2.396, P >0.05). The timeliness of diagnosis increased in 2019 compared with 2015 ( H onset–initial diagnosis =14.186, P 0.05; Z initial diagnosis – diagnosis = –0.197, P >0.05). Conclusion The timeliness of malaria diagnosis has been improved in Changsha, we should continue to do a good job in the prevention and control of imported malaria. Malaria control threshold should be moved forward. 摘要:目的 分析2015—2019年长沙市输人性疟疾疫情,为巩固消除疟疾成果和今后的防控工作提供依据。 方法 通过国家传染病报告信息管理系统和寄生虫病防治信息管理系统,收集整理2015—2019年长沙市疟疾病例信 息,描述疟疾病例的流行病学特征,对疟疾诊断机构、诊断及时性、病情等情况采用 χ 2 检验、秩和检验进行统计分析。 结果 2015—2019年长沙市共报告290例疟疾病例,全部为境外输人性病例,其中恶性疟患者占74.83% ;长沙市9个辖 区(县、市)均有病例报告和分布,现住址为本市病例151例,外地病例139例;疟疾患者以中青年男性务工人员居多;市 级医疗机构诊治病例数最多,省级医疗机构诊断率最高,省、市、县三级医疗机构初诊到诊断间隔时间差异无统计学意 义( H =2.396, P >0.05)；2019年相对于2015年诊断及时性上升( H 发病-初诊 =14.186, P 0.05; Z 初诊-诊断 =-0.197, P >0.05)。 结论 长沙市输人性疟疾诊断及时性有所 提升,应继续做好输人性疟疾防控工作,疟疾防控关口前移。
