In this paper, based on the data of the incidence of schistosomiasis in China from January 2011 to May 2018 we establish SARIMA model and NARX model. These two models are used to predict the incidence of schistosomiasis in China from June 2018 to September 2018. By comparing the mean square error and the mean absolute error of two sets of predicted values, the results show that the NARX model is better and it has an e ective forecasting precision to incidence of schistosomiasis. Then according to the results, a mixed model called NARX-SARIMA model is used to predict the incidence future trends and make a comparison with the two model. The mixed model has a better application based on its good fitting capability.

Schistosomiasis is caused by infection with trematode flukes of the genus Schistosoma. More than 700 million people worldwide are estimated to be susceptible to infection. In sub-Saharan Africa, schistosomiasis is the second most widespread neglected tropical disease after malaria.

In recent decades, technological advancements and scientific progress have significantly improved disease control strategies. However, the exclusive focus on these aspects often overlooks the crucial role of social and cultural factors. Local narratives, reflecting community traditions and beliefs, offer valuable insights that can influence the success of public health interventions.

Background: Schistosomiasis, a neglected tropical disease, affects approximately 40 million women of reproductive age contributing to preventable anaemia during pregnancy, intrauterine growth retardation and low birth weight. In spite of the high prevalence rate of this disease among school aged children in Abakaliki, no study in Abakaliki has looked at the burden of Schistosomal infection in pregnancy with a view to determining maternal and neonatal outcomes.
Objective: To determine the association between schistosomal infection and maternal anemia, low birth weight, and other neonatal outcomes in Abakaliki.

Background: Brazil has the second highest case count of Hansen's disease (leprosy, HD), but factors contributing to transmission in highly endemic areas of the country remain unclear. Recent studies have shown associations of helminth infection and leprosy, supporting a biological plausibility for increased leprosy transmission in areas with helminths. However, spatial analyses of the overlap of these infections are limited.

Background: Genomic analysis has revealed extensive contamination among laboratory-maintained microbes including malaria parasites, Mycobacterium tuberculosis, and Salmonella spp. Here, we provide direct evidence for recent contamination of a laboratory schistosome parasite population, and we investigate its genomic consequences. The Brazilian Schistosoma mansoni population SmBRE has several distinctive phenotypes, showing poor infectivity, reduced sporocyst number, low levels of cercarial shedding and low virulence in the intermediate snail host, and low worm burden and low fecundity in the vertebrate rodent host.
