Insights into the elimination of vivax malaria in China

Fang Huang, Li Zhang, Zhi-Gui Xia

Malaria is caused by multiple parasitic species of the genus Plasmodium. Plasmodium vivax is the most geographically widespread and poses challenges in elimination due to its unique biological and epidemiological characteristics. The aim of study was to highlight the practices and experience targeting vivax malaria control and elimination in China. P. vivax malaria was historically endemic in more than 70% of counties in China, with reported vivax malaria cases as high as 26 million a year. After around 70 years of effort, China was certified as malaria-free in June of 2021. The key insights into China's vivax malaria control and elimination were offered, including radical cure strategies, comprehensive but adaptive strategies targeting species of Plasmodium and Anopheles, mass drug administration, and case-/focus-centred surveillance and response systems. The complete global eradication of P. vivax and eventually malaria will be more difficult, and China's practices and experience could be a valuable reference in this campaign.
