An epidemiological study of 1,136 inhabitants from two rural communities in Owan East local government area of Edo State, Nigeria was investigated to ascertain the prevalence, intensities and urinary symptoms in Schistosoma haematobium infections. In both communities, 371 (32.6%) of the villagers screened, excreted S. haematobium with a mean of 40.1 ova per 10 ml of their urine. The pattern of infection was highest among the school children, moderate among the farmers and least among the civil servants. The sensitivities of their urinary symptoms associated with this parasitic infection in these communities are 78.7% hematuria, 71.9% proteinuria, 70.4% supra public pain/discomforts and 59.6% dysuria. These foci of infections will broaden the epidemiological picture of urinary schistosomiasis in this part of the globe.

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.

Urinary schistosomiasis is caused by the blood fluke , which is predominantly found in Africa. The freshwater snail is its main intermediate host. The species that make up the group are genetically complex, and their taxonomic status remains controversial.

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.

Background: The freshwater snails Biomphalaria alexandrina and Bulinus trancatus are key contributors to the transmission of S. mansoni and S.haematobium, respectively, for being their intermediate hosts.
