Imported Plasmodium falciparum and locally transmitted Plasmodium vivax: cross-border malaria transmission scenario in north-western Thailand
This project aims to do an in-depth data analysis and mathematical modelling of entomological, ecological and human interactions that affect malaria transmission in the endemic area along Thai-Myanmar border.
Cross-border malaria transmission is an important problem for national malaria control programmes. The epidemiology of cross-border malaria is further complicated in areas where Plasmodium falciparum and Plasmodium vivax are both endemic. By combining passive case detection data with entomological data, a transmission scenario on the north-western Thai–Myanmar border where P. falciparum is likely driven by importation was described, whereas P. vivax is also locally transmitted. This study highlights the differences in the level of control required to eliminate P. falciparum and P. vivax from the same region.
