Abstract: A cross-sectional study to evaluate malaria parasitaemia among 1000 Outpatients (418 males and 582 females) in Braithwaite Memorial Specialist Hospital (BMSH) Rivers State, Nigeria was conducted. Blood samples were collected through venous procedure from the study subjects and the presence of malaria parasites was observed microscopically on thick and thin stained blood films prepared from each blood sample according to standard parasitological techniques. All data gotten were statistically analyzed using Chi-square test and analysis of variance (ANOVA) with a p-value less than 0.05 considered significant. Plasmodium falciparum was the only malaria parasite identified in this study.
