Prevalence of Schistosomiasis Among School Children in Bahri Locality, Sudan

Abstract

Schistosomiasis is a neglected tropical disease caused by blood flukes (trematode worms) the genus Schistosoma. Schistosomiasis is a chronic, debilitating disease that affects the populations of tropical and subtropical countries, especially children at School-age. In Sudan schistosomiasis is a major health problem adversely affecting the health of vulnerable populations. A cross-sectional study was conducted to determine the prevalence of schistosomiasis among school children in selected basic schools in Bahary Locality, Khartoum State, Sudan from December 2017 to January 2018. Urine and faecal samples were collected from 600 school-aged children and examined for the eggs of S. haematobium and S. mansoni using standard sedimentation and Kato technique, respectively. The overall of prevalence schistosomiasis 16,5% which the prevalence of S. haematobium among pupils examined was 16% and the prevalence of S. mansoni was 0.5%. Additionally, male’s reported higher prevalence (22.7%) of S. haematobium than the female’s (4.1%) also males reported higher prevalence of S. mansoni female with prevalence rate 7.7% and 2.2% for males and females respectively. According to the study participant age-groups; age group 13-15 years had the highest prevalence (22%) of S. haematobium was recorded and age group 10- 12 years comes next (18.5%) followed by age group 6 -9 years (7.5%); this difference of the age group as a factor was statistically significant (x2 = 17.9 –p value n =0.0) , but in S. mansoni age group 10-12 years had the highest (0.8%) prevalence , also there was statistically significant (P=0.04). This study highlights that schistosomiasis is a public health problem among children in Bahary locality. The findings of the study suggested appropriate intervention against schistosomiasis such as mass treatment, health education and control of the intermediate snail host.

Prevalence and Intensity of Urinary Schistosomiasis Among Selected People in Tulus Area, South Darfur State, Sudan

“…In contrast, the present study showed very much higher prevalence of S. haematobium compared to that obtained from nationwide survey (5.2%), even though, South Darfur States was the second most endemic area with a prevalence of 13.91% in that survey (9). Moreover, many other nding across the country reported lower ndings when the S. haematobium diagnostic stages were screened particularly among children (11,16,17). Such as that of Hajissa et al (2018) (8,18,19).…”

“…Thus, Sudanese government prioritised collecting data on the burden of NTDs, particularly schistosomiasis. In response; many epidemiological studies were conducted in central and east Sudan (10,11), with relatively few, if any, such studies being conducted in Darfur area.…”

“…9 Moreover, many other finding across the country reported lower findings when the S. haematobium diagnostic stages were screened particularly among children. 11,16,17 Worldwide, similar observation of high egg positive rate was also made in Senegal (57.6%) while in many other country the rates were slightly lower such as those reported from Nigeria (48%), Gabon (45%), Malawi (10.4%). 1,4,6,20 This variation could be due to study period, target population, environmental condition, sample size variations and the method of laboratory diagnosis.…”

“…In response; many epidemiological studies were conducted in central and east Sudan, with relatively few, if any, such studies being conducted in Darfur area. 10,11 Therefore, this study was conducted to estimate the prevalence and intensity of S. haematobium infection in selected populations from the city of Tulus, South Darofur State. The study revealed that the percentage of infected people with S. haematobium infection based on urine filtration method was 62% (62/100).…”
