收集整理寄生虫病防治信息管理系统中2020年全国31个省（直辖市、自治区,未包括台湾、香港和澳门地区）疟疾疫情数据资料,对疟疾疫情特征进行统计分析。2020年全国累计报告疟疾病例1 086例,较2019年（2 674例）下降了59.4%;其中境外输入性病例1 085例,长潜伏期三日疟病例1例,无本土原发蚊传疟疾病例报告;中国籍1 051例（96.8%,1 051/1 086）,外国籍35例（3.2%,35/1 086）;男女性别比为13.7 ∶ 1;主要集中在30~49岁年龄组（57.5%,624/1 086）;间日疟234例（21.5%,234/1 086）,恶性疟610例（56.2%,610/1 086）,三日疟23例（2.1%,23/1 086）,卵形疟204例（18.8%,204/1 086）,混合感染15例（1.4%,15/1 086）。29个省（直辖市、自治区）有病例报告,报告病例数位居前5位的省份依次为广东、云南、江苏、四川和山东,累计报告疟疾病例570例（52.5%,570/1 086）。全国共报告疟疾死亡病例6例（0.6%,6/1 086）,由广东省（3例）、福建省（2例）、湖北省（1例）上报,较2019年的19例（0.7%,19/2 674）下降了68.4%。我国已经连续4年无本土原发蚊传疟疾病例报告,应继续加强输入性疟疾和边境疟疾的监测,防止疟疾输入再传播,减少死亡风险,巩固消除疟疾成果。

Malaria epidemic data in 31 Provinces/Municipalities/Autonomous regions (Taiwan region, Hong Kong and Macao excluded) of China in 2020 were collected and sorted through the Information System for Parasitic Disease Prevention and Control. The epidemiological characteristic of malaria was analyzed. In 2020, a total of 1 086 malaria cases were reported in China, which declined by 59.4% compared to that in 2019 (2 674). Of these cases, 1 085 imported cases and 1 long incubation case infected with Plasmodium malaria were identified. None of them were indigenous cases. In addition, 1 051 cases were of Chinese nationality (96.8%, 1 051/1 086) and 35 cases were of foreign nationality (3.2%, 35/1 086). Most of the cases were within the age range of 30-49 years (57.5%, 624/1 086), with a male-to-female ratio of 13.7 ∶ 1. The reported cases included 234 cases of P. vivax infection (21.5%, 234/1 086), 610 cases of P. falciparum infection (56.2%, 610/1 086), 23 cases of P. malariae infection (2.1%, 23/1 086), 204 cases of P. ovale infection (18.8%, 204/1 086) and 15 cases with mixed-infection (1.4%, 15/1 086). The cases were reported from 29 Provinces/Municipalities/Autonomous regions, with the top 5 being Guangdong, Yunnan, Jiangsu, Sichuan and Shandong provinces, from which 570 cases (52.5%, 570/1 086) were reported. Totally 6 deaths (0.6%, 6/1 086) were reported from Guangdong (3 cases), Fujian (2 cases) and Hubei (1 case) provinces, which was decreased by 68.4% compared to the 19 deaths in 2019. Noticeably, there has been no report of indigenous cases since the last four years. Nevertheless, it is imperative to continuously strengthen the surveillance on imported malaria and the cases in border area, prevent from re-transmission of imported malaria, reduce the death risk and consolidate the achievements of malaria elimination in China.
