oa South African Medical Journal - Intestinal bilharziasis in the Eastern Transvaal : a preliminary report
A S. mansoni survey was done together with liver and spleen rates on 819 Native school children in the low veld of the Eastern Transvaal. No difference was observed with regard to the observations on the two sexes. There is a definite correlation between the S. mansoni intensities found and the liver rates, and it seems reasonable to suppose that in places where the S. mansoni intensity is high, and therefore where the individual infestation is heavy, considerable liver damage is being caused amongst the Native population. Certain common factors were observed which might have some bearing on the degree of intensity of the disease in anyone particular area.
