The resurgence of vivax malaria in the ROK Armed Forces personnel near the DMZ was successfully suppressed through the implementation of a mass malaria chemoprophylaxis programme initiated by the MND in 1997, as well as several other factors that may have contributed to the reduction of malaria transmission since 2000.

The number of Anopheles spp. positive for P. vivax sporozoites correlated with the monthly number of malaria cases and exposure of ROKA soldiers from May–October to P. vivax malaria infections.
The fact that the highly polymorphic kdr gene is only observed in An. sinensis s.s. out of the six Anopheles species and their geographical distribution suggest the need for future studies of insecticide resistance monitoring and investigations of species-specific resistance mechanisms in order to build successful malaria vector control programmes in the ROK.
