“…Prior to the baseline survey of this study, SACs in Al Jabalain had received MDA interventions twice during the 4 years of the 1st phase of the KOICA project, while those in El Salam had not. In 2013, the baseline prevalence of S. haematobium infection was 35.2% in El Salam, which was similar to that in previous studies in the White Nile State [5,6,22], while the 2013 baseline prevalence in Al Jabalain was 9.1% due to previous MDA intervention within 4 years [5]. In this study, the reduction in the prevalence of infection after MDA was 80.3% in Al Jabalain and 84.4% in El Salam.…”

“…Human schistosomiasis caused by S. haematobium is one of the major public health concerns in Sudan. Previous studies showed that the prevalence of S. haematobium infection in the White Nile State of Sudan was 28.5% [ 5 ], 45.0% [ 6 ], 21.9% [ 21 ], and 35.6% [ 22 ] in different survey areas and times. In this study, we compared changes in the prevalence and intensity of S. haematobium infection between Al Jabalain and El Salam districts of White Nile State before and after MDA intervention.…”

This study aimed to investigate whether mass drug administration (MDA) intervention has an equivalent effect on reducing the prevalence and intensity of Schistosoma haematobium infection regardless of the baseline values. A repeated cross-sectional survey was performed targeting students of 12 primary schools in Al Jabalain and El Salam districts of White Nile State, Sudan, at both 1 week before and 8 months after the MDA. Prior to the baseline survey, school-aged children in Al Jabalain had received MDA interventions twice in 4 years, while those in El Salam had not. The baseline prevalence was 9.1% in Al Jabalain and 35.2% in El Salam, which were reduced to 1.8% and 5.5% at 8 months after the MDA, respectively. The corresponding reduction rates were 80.3% and 84.4%, not significant difference between both districts. However, changes in the geometric mean intensity (GMI) of egg counts were significantly different between both districts. The baseline GMIs were 14.5 eggs per 10 ml of urine (EP10) in Al Jabalain and 18.5 EP10 in El Salam, which were reduced to 7.1 and 11.2 EP10 after treatment, respectively. The corresponding reduction rates were 51.0% and 39.5%. In conclusion, MDA interventions were found to bring about similar relative reduction in prevalence regardless of the baseline value; however, the relative reduction in infection intensity was more salient in the district with a low baseline value for both prevalence and intensity. This clearly points to the importance of repeated MDA interventions in endemic areas, which will eventually contribute to schistosomiasis elimination.

“…The urine samples were rst observed whether show occult or gross hematuria, and then examined for the presence of S. haematobium eggs by membrane ltration technique as described previously [10]. In brief: all urine samples of su cient quantity were shaken, subsequently, 10 ml of each sample were pressed through a polycarbonate lter with a pore size of 20 µm (Sterlitech, Kent, WA, USA) using a standard 10 ml plastic syringe, the membrane was then put on a microscope slide, covered with a piece of hydrophilic cellophane soaked in glycerol solution, and examined under the microscope by trained laboratory technicians using some drops of Lugol's iodine to stain S. haematobium eggs after cellophane coverage.…”

Objective: Urinary schistosomiasis is a major public health issue in Sudan. The disease is endemic in many rural communities across the country. This is a cross-sectional study conducted to determine the prevalence and intensity of urinary schistosomiasis among selected induvial in the city of Tulus, South Darfur state, Sudan. One hundred terminal urine samples were collected and examined for Schistosoma haematobium eggs using standard filtration technique.Results: A total of 100 individual were enrolled in the study with a mean (± SD) age of 17.7 ± 0.73 years. Out of them, 62 (62%) were found to be infected with Schistosoma haematobium. The statistical analysis showed significant association with gender (P = 0.043) with higher prevalence 70.9% (39/55) in female than males 51.1% (23/45). Majority of the S. haematobium infections were classified as intense infection (82%, 51/62) with egg count ≥ 50 eggs/10 ml urine, while gross haematuria was observed in 10% of urine samples. Further studies, including large sample size will be essential to assess the burden of the disease in the study area.

Background: Preventive chemotherapy (PC), is the main elimination strategy against Soil-Tansmitted Helmenthiasis (STH) and Schistosomiasis (SCH) recommended by the world health organization (WHO), should be strengthened through identification of the remaining SCH transmission foci and evaluating its impact to get lesson. This study was aimed to assess the prevalence of STH/SCH infections, intensity of infections and associated factors among School Age Children (SAC) in two districts, previously not known to be endemic for SCH in Southern Ethiopia, October to December 2019.Methods: Structured interview questionnaire was used to collect data, the record of treatment coverage against STH was reviewed and stool samples collected from 2114 children were diagnosed using Kato-Katz technique. Multilevel logistic regressions were used to assess the association of infections with potential predictors. Results: The reviewed treatment coverage ranges from 92% to 106% in both districts. The prevalence of STH infection was 33.3% with 95% confidence interval (CI) of 31.3% to 35.4%. The intensity of infections was light (93.8%, 99.2% & 92.5%), moderate (4.7%, 0.8% & 7.5%) and heavy (1.5%, 0% & 0%) for hookworm, whipworm and Roundworms respectively. STH infection was higher among male SAC with Adjusted Odds Ratio (AOR) of 1.7; 95%CI: 1.4-2.1); occupation of the household head other than farmer or house wife (AOR=0.6; 95%CI: 0.4-0.9) and with higher wealth index (AOR=0.7; 95%CI: 0.5-0.9) as compared to the poorest one. The prevalence of S.mansoni in Dara Mallo district was 34.5% (95%CI: 31.1-38.1%). Light, moderate and heavy S.mansoni infections were 42.9%, 33.7% and 23.4% respectively. Children from mothers aged 50 or above years were significantly more likely infected by S.mansoni (AOR=5.9; 95%CI: 1.4-27.4) as compared to children from mothers (caretakers) of 34 or lower age.Conclusions: Though high PC coverage were reported, STH remained moderately endemic while S.mansoni became moderate endemic in Dara Mallo, requiring sub-district level mapping and deworming campaign initiations. Evidence based strategies which supplement the existing interventions focusing on the identified factors are important to realize the set targets.
