Abstract

We carried out a parasitological survey of Schistosoma haematobium infection among the residents of Lowveld Siphofaneni, Swaziland, an area which is devoid of sanitation. Subjects with positive infection were confirmed by the detection of S. haematobium ova in their urine. The intensity of the infection was estimated by calculating the total number of S. haematobium ova present in 10 ml urine specimen (geometric mean intensity; GMI). Overall, the prevalence of S. haematobium infection was 6.1% (18/295) with a GMI of 20.7 (95% CI = 9.1~32.2). Female (10.5%, 16/153) had significantly higher prevalence than that in male (1.4%, 2/142) (ORs = 8.2, 95% CI = 1.8-36.2, P <0.01); conversely, male had higher GMI (60.0) than that (17.3) in female. The age group of ≤5 yrs (15.3%, 9/59) had significantly higher prevalence than that in age group of ≥19 yrs (2.6%, 3/115) (ORs = 0.2, 95% CI =0.04-0.57, P <0.01). The highest GMI of 27.9 (95% CI = 7.6~48.2) was also seen in age group of ≤5 yrs.
