Transnational spread of multidrug resistant PfPailin

The artemisinin resistant Plasmodium falciparum C580Y lineage ( PfPailin ) was detected first in Pailin, Western Cambodia, in 2008. 2 It later acquired piperaquine resistance and spread east. 8 years later it has now reached the south of Vietnam encompassing all four countries of the Eastern Greater Mekong subregion (Imwong et al., LID, 2017)
