To study the epidemiological distribution and the incident trends of imported malaria from 2012 to 2016 in Zhejiang Province, southeastern China, we collected data on malaria from the Information System for Parasitic Disease Control and Prevention. A total of 1,003 malaria cases were reported during 2012-2016, and all of these cases were imported. was the predominant species (76.3%) in Zhejiang Province. The percentage of decreased from 33.6% to 8.1%, whereas the percentage of and increased. Most cases were male (89.8%), mostly in the age group of 21-50 years (82.6%). Businessmen (33.0%), workers (21.0%), farmers (18.8%), and overseas laborers (11.7%) were at high risk. The origin of the largest number of imported cases was Africa (89.5%), followed by Asia (10.0%) and Oceania (0.5%). The time interval from illness onset to confirmation was found to be significantly associated with the complications of patients. Out of 3,461 febrile individuals tested during reactive case detection, 10 malaria-positive individuals were identified. Effective surveillance and response system should be strengthened to prevent the reintroduction of malaria.
为研究 2012 至 2016 年中国东南部浙江省输入性疟疾的流行分布和发病趋势，我们从寄生虫病防治信息系统收集疟疾数据。2012-2016 年共报告 1003 例疟疾病例，均为输入性病例。间日疟（76.3%）是浙江省的主要疟疾病种。恶性疟的比例从 33.6%降至 8.1%，而卵形疟和三日疟的比例有所增加。大多数病例为男性（89.8%），年龄组主要为 21-50 岁（82.6%）。商人（33.0%）、工人（21.0%）、农民（18.8%）和海外劳工（11.7%）为高风险人群。输入性疟疾病例最多来自非洲（89.5%），其次是亚洲（10.0%）和大洋洲（0.5%）。发病至确诊的时间间隔与患者的并发症明显相关。在 3461 名发热个体进行的反应性病例检测中，发现 10 名疟原虫阳性个体。应加强有效的监测和应对系统，以防止疟疾的再次传入。
