ABSTRACT
A cross sectional descriptive study was conducted during the period from September 1997 to February 1998 in Tragma area; a part of an irrigation scheme located on the Eastern bank of the River Nile, 200 km North of Khartoum, in order to determine point prevalence and clinical characteristics of malaria in the area. The study consisted of two household surveys followed by a hospital-based study. Prevalence of malaria was 0.09% [1/1053] during September and 16.7% [119/711] during December survey. Plasmodium falciparum was detected in 120 [9.2%] of 1300 patients who reported to hospital during the study period. Both infection rate and mean parasite count/Mu l of Plasmodium falciparum decreased significantly with age [P<0.05]. Fever and low haemoglobin were found to be associated with Plasmodium falciparum infection [P <0.05]. No associations were observed between Plasmodium falciparum and digestive system symptoms or leucocyte count
