A study on relapse/re-infection rate of Plasmodium vivax malaria and identification of the predominant genotypes of P. vivax in two endemic districts of Nepal

Abstract

The relapse/re-infection rate of 17% was determined for P. vivax in Kailali and Kanchanpur districts of Nepal. A heterogeneous Pvcsp genotypic distribution of P. vivax was detected with VK210 being a predominant type, suggesting a complex transmission dynamics of the parasite. Expanding such study in other endemic regions of Nepal would help provide a complete picture on relapse/re-infection rate and parasite genotypic variability that can help in effective control and management of malaria in Nepal.
