Malaria re-importation risk and control needs in the border region,Yunnan
Recently,malaria incidence has sharply resurgence in the border area of northern Myanmar,with the parasite incidence rate in 2023 being 21.47 times(95％CI:18.84-24.48)that of 2019 in Kachin State's Razan and nearby areas.This resurgence caused the number of imported malaria cases to increase from 188 in 2019 to 398 in 2023 in Yunnan Province.In addition to the impact of military conflict,the border malaria joint prevention and control cooperation mechanism and malaria control measures established between China and Myanmar have failed to be implemented effectively due to the impact of the international COVID-19 epidemic.Hence,it is recommended that relevant departments evaluate the quality and effectiveness of the current cross-border transmission measures for malaria in the China-Myanmar border area from a technical perspective,and provide a large demand for primaquine,which can block the spread of malaria and cure vivax malaria,in response to the current prevalent characteristics of vivax malaria predominating in northern Myanmar.Moreover,to effectively reduce the mortality of imported malaria patients and prevent re-importation and transmission,it is necessary to enhance clinical physicians'knowledge,awareness,and vigilance regarding malaria diagnosis and treatment in the Yunnan border region,as well as China's ability and quality of appropriate response to imported malaria.
