Approximately 5,000 cases of imported malaria are observed each year in metropolitan France. Guidelines for the prevention and management of imported malaria were published by the French infectious disease society (French acronym SPILF) in 2017.
China has reached important milestones in the elimination of malaria. However, the numbers of imported recurrent cases of Plasmodium vivax and P. ovale are gradually increasing, which increases the risk of malaria re-establishment in locations where Anopheles mosquitoes exist. The aim of this study is to characterize the epidemiological profiles of imported recurrent P. vivax and P. ovale cases, quantifying the recurrence burden and guiding the development of appropriate public health intervention strategies.
