A better understanding of the occurrence and risk of Plasmodium vivax infection among
Duffy-negative individuals is required to guide further research on these infections across …

Reports of P. vivax infections among Duffy-negative hosts have accumulated throughout sub-
Saharan Africa. Despite this growing body of evidence, no nationally representative …

Although Plasmodium vivax has been assumed to be absent from sub-Saharan Africa
because of the protective mutation conferring the Duffy-negative phenotype, recent evidence …

Objectives Plasmodium vivax malaria was thought to be rare in Africans who lack the Duffy
blood group antigen expression. However, recent studies indicate that P. vivax can infect …

Background Plasmodium vivax shows a small prevalence in West and Central Africa due to
the high prevalence of Duffy negative people. However, Duffy negative individuals infected …

Background Due to the recently observed rise in Plasmodium vivax incidence in Sudan and
reported transmission in Duffy-negative individuals; we aimed to assess the possibility of P …
