[New challenges of malaria elimination in China].

National malaria elimination action was initiated in china, 2010. The strategy of malaria elimination focused on the investigation and disposal of malaria case and foci, and technical measure of '1-3-7' model was implemented to ensure effective case detection and validation, case category and treatment, and the foci identification and disposal. During the past several years, the geographic scope of malaria transmission was shrunk sharply, and a overwhelming majority of areas have successfully interrupted local transmission of malaria. However, to achieve the goal of national malaria elimination in 2020, several new challenges were faced, which included the following ones: local malaria sustained transmission in the cross-bordering and remote areas, increasing trend of overseas imported malaria, introduced malaria among domestic migrant population, and the elimination of species of P. vivax and P. oval. Therefore, in the specific areas and among the high-risk population, it's critical to take effective actions to ensure malaria case and transmission foci detection, identification, classification, and disposal in the following years.
