A comparative epidemiological study of malaria between children of Northern and Southern Sudan

A malaria survey on 1014 Northern and 1023 Southern Sudanese children showed a parasite rate of 1.08 and 62.5 per cent respectively. Among febrile children the slide positivity rate was 43.8 per cent in the Northern Sudan and 58 per cent in the Southern study. Plasmodium falciparum was the only species detected in the North. In Southern Sudan the species prevalence rate was P. falciparum, 84.4 per cent, P. vivax, 8.5 per cent, P. malariae, 6.8 per cent and P. ovale, 0.15 per cent. Enlarged spleens were found in 36.3 per cent of the school children studied in the South; none of the 1014 school and kindergarten children surveyed in the North had splenomegaly. Ref.
