3种重要输入性寄生虫病的流行现状及新的挑战

经过近70年的艰苦努力，我国寄生虫病防治工作取得了举世瞩目的成就，一些重要寄生虫病已经达到或正在迈向消除。随着社会和经济的发展、“一带一路”倡议的逐步实施和推进、国内外交流和对外投资的增加，我国外出务工、经商、留学、旅游、探亲以及参与国内外交流活动的人员日益增多，导致国内从流行区到非流行区、全球从国外到国内的输入性寄生虫病病例逐渐增多。输入性病例增多给我国寄生虫病消除工作带来了新的挑战。本文分析了我国疟疾、血吸虫病和利什曼病这3种重要输入性寄生虫病的流行现状及当前防控工作面临的新挑战，并提出了相关应对策略和措施。

Current status and new challenges of three important imported parasitic diseases

Following the concerted efforts for nearly 70 years, great achievements have been obtained in parasitic diseases control in China, and some important parasitic diseases have been eliminated or moving towards elimination in the country. With the socioeconomic development, the implementation of the “Road and Belt Initiative” and the increase in the international communication and overseas investment, there is a rise in the number of overseas labors, businessmen, students, travelers, visitors and participants in national and international communication activities, resulting in a gradual increase in the number of cases with parasitic diseases imported from endemic to non?endemic areas of China and from foreign countries to China. The increase in the number of imported cases causes new challenges for the elimination of parasitic diseases in China. The paper describes the current status of malaria, schistosomiasis and leishmaniasis, analyzes the challenges for the current control activities, and proposes the control strategies and interventions.
