Background: Tanzania has a high prevalence of urogenital schistosomiasis. Praziquantel is administered to school-age children on an annual basis as part of efforts to reduce transmission and morbidity associated with heavy infections. We investigated the prevalence, knowledge, and practices of urogenital schistosomiasis transmission, as well as compliance with mass drug administration (MDA) among schoolchildren in Masasi District.
Materials And Methods: A cross-sectional survey was conducted in five primary schools. A pre-tested questionnaire was used to assess knowledge and practice related to the transmission of urogenital schistosomiasis, as well as compliance with MDA. Collected urine samples were examined macroscopically for macrohematuria. They were then tested for microhematuria and () eggs with urine dipsticks and filtration technique, respectively.
Findings: The study included 389 primary school children in total. Overall, 27 (6.9%) of children had infection, and 37 (9.5%) had microhematuria. The mean (SD) intensity was 123.4 (247.4) eggs per 10 ml of urine. A total of 10 (2.6%) had heavy intensity of infection. The majority (94.9%) reported having complied to the previous round of MDA six months prior to this study, and 308 (79.2%) were aware that water contact is associated with an increased risk of urogenital schistosomiasis infection. Nevertheless, 182 (46.8%) of the participants engaged in swimming activities, with 92 (50.9%) of the participants being female. The prevalence of urogenital schistosomiasis was higher (10.9%) among children who participated in swimming activities versus those who did not (3.4%) ( = 0.003).
Conclusion: Despite high MDA compliance, urogenital schistosomiasis is still prevalent among primary school children in Masasi District. Children who swim in freshwater bodies such as rivers and ponds are more likely to contract urogenital schistosomiasis.

Background: Regular mass drug administration of praziquantel has a positive impact on reducing the burden of human schistosomiasis, however transmission still persists in many areas. To reach disease elimination; tailored interventions are needed to not only further reduce infections but also to tackle areas of persistent high prevalences of infection. One proposed approach is timed treatment based on the natural disease transmission cycle in relation to seasons.

Background: Schistosoma haematobium is the causative pathogen for urogenital schistosomiasis. To achieve progress towards schistosomiasis elimination, there is a critical need for developing highly sensitive and specific tools to monitor transmission in near-elimination settings. Although antibody detection is a promising approach, it is usually unable to discriminate active infections from past ones.

Schistosomiasis, caused by Schistosoma worms, is a major neglected tropical disease in Africa, this disease is ranked as second after malaria. Nanotechnology is important for treating schistosomiasis while minimizing chemotherapy side effects. The current investigate aimed to assess the effectiveness of biosynthesized zinc oxide nanoparticles (ZnO NPs), which were used for the first time in an attempt to find alternative treatment for schistosomiasis and synthesized by Origanum majorana, and to compare them with praziquantel (PZQ), the only chemical treatment approved by the World Health Organization.

Different agencies have emphasized the need to evaluate current serological methods for screening patients with suspected urogenital schistosomiasis. However, there is still a lack of evidence regarding the most appropriate methods for this purpose. Here we assessed the diagnostic efficacy of a newly developed serological technique that utilizes the recombinant protein -TSP-2, applied to the urine and serum of migrants suspected of having urogenital schistosomiasis.

Schistosomiasis poses a significant global health threat, particularly in tropical and subtropical regions like Sudan. Although numerous epidemiological studies have examined schistosomiasis in Sudan, the genetic diversity of Schistosoma haematobium populations, specifically through analysis of the mtcox1 gene, remains unexplored. This study aimed to investigate the risk factors associated with urogenital schistosomiasis among school pupils in El-Fasher, Western Sudan, as well as the mtcox1 genetic diversity of human S.
