Studies on Schistosoma haematobium... ( Cont.. 6)
Relationship between visible/subjective haematuria and intensity of infection with S. haematobium.

Relationship between visible/subjective haematuria and intensity of infection with S. haematobium.
The overall
prevalence of visible haematuria was 7.1%. Percentage of pupils from C.A.C
primary school Modakeke that were positive for haematuria was 7.8% while 6.3%
of pupils from L.A primary school Sabo.This difference in percentage haematuria
is not statistically significant (p>0.05). The overall intensity of
infection expressed as range is 1-51 eggs/10ml urine (Table 4).
The completed
questionnaires administered to pupils were used for subjective analysis; 20.2%
of the overall pupils have pain when urinating, 11.1% in their lifetime had
seen blood in their urine and 21.2% go to streams or rivers. Boys had higher
percentage than girls (31.4% and 10.4%, respectively).

4.5 Relationship
between prevalence of infection with S. haematobium and occupation of
parents.
Table 5 shows
Prevalence with regards to occupation of parents. Pupils whose parents were traders were most infected.
Table 5
Figure 1 shows the prevalence in
relation to age groups, which increased suddenly until it got to the peak under
the age group 13 – 14 years and abruptly declined. The intensity of infection
in relation to age groups showed a similar pattern (Figure 2).
