摘　　要：Introduction:Laiza and nearby areas(LNA)in Myanmar are identified as the primary malaria hotspots in the bordering regions of Yunnan Province,China.Methods:Six sentinel surveillance sites were established at the China-Myanmar border in LNA to monitor malaria.Data from 2019 was used as a baseline to analyze malaria incidence and trends in LNA and Myanmar,as well as the importation of malaria cases into China from 2019 to 2023.Results:Plasmodium vivax was the predominant species,representing 99.95%(14,060/14,066)of confirmed malaria cases in LNA.A total of 8,356 malaria cases were identified in 2023,with an annual parasite incidence(API)of 19.78 per 100 person-years.Compared to 2019,the incidence rate ratio was 21.47(95%confidence interval:18.84,24.48),indicating that the API in 2023 was 21.47 times higher than that in 2019.In Yunnan,out of 1,016 reported cases,545 imported cases(53.64%)originated from LNA and spread to 18(13.95%)out of 129 counties.Ten provinces in China,including Yunnan,reported imported malaria cases from LNA in Myanmar.Conclusions:The increase in population,particularly among internally displaced persons,along with inadequate healthcare services,has led to a notable resurgence of malaria in LNA.This resurgence poses a risk to preventing the re-emergence of malaria transmission in China.There is an urgent need for novel collaborative policies,as well as financial and technical assistance,to enhance malaria control efforts in LNA,Myanmar.
