Prevalence of Plasmodium vivax species in Elhajyosife area in Shergalnile locality in Khartoum State

Abstract

Background: Plasmodium vivax malaria has been recognized as an important cause of morbidity in several African countries. The prevalence was previously estimated as 12.5% in Khartoum. These estimates are observed to be rising and spreading continuously. Aim: The present study was undertaken to investigate the situation of distribution of P. vivax malaria in Elhajyousiff area in Khartoum State-Sudan. Methods: Cross-sectional malaria surveys carried out in Elhajyousiff area (Khartoum State) during the period of August 2021 to September 2021 .Atotal number of 250 blood samples were examined by microscopical examination. The samples were collected from different centers in Elhajyousiff area (Albanjadeed Hospital, Almaygoma Health Center and Alsheeda Nada Health Center). All samples were examined by direct microscopy for plasmodium species using blood film (Thick and thin). Results: From 250 samples there were 241(96.4%) samples negative, 5(2.0%) samples were positive for P.falciparum and 4(1.6%) samples were positive for P.vivax. The P. falciparum showed as more common species in area. Conclusions: Even though malaria in Shergalnile locality is still largely recognized to Plasmodium falciparum, P. vivax has been growing with worrying proportions and spreading to new areas. The emergence and marked increase of P. vivax poses new challenges to malaria treatment and control in Elhajyousiff area.
