Risk level determination was assessed using the Delphi method and a risk matrix method. Control measures were implemented based on the risk levels determination. Effectiveness evaluation was verified by monitoring schistosomiasisrelated public health incidents and tracking key indicators—including oncomelania snail infection prevalence, snail density, human and livestock infection rates, wild feces detection, and sentinel mouse infection—over 1–3 years post-event, supplemented by repeated risk assessments.  \nResult  \nThe decision-making support system for schistosomiasis transmission prevention and control during large-scale events comprises a database of recent schistosomiasis cases, onsite schistosomiasis transmission risk monitoring, a case database of outbreaks, a database of assessment experts, a database of the distribution of oncomelania snail, a library of professional strategies, and a preplan.

Post-event surveillance and reassessment of indicators verified the sustained effectiveness of the interventions. This closedloop approach demonstrates that risk assessment is a vital tool for public health decision-making during large events in endemic areas.  \nAuthor summary  \nOrganizing large public events like festivals, construction projects, or internationa","cbCaikh6dxAsxXNg","https://ap.wps.com/l/cbCaikh6dxAsxXNg","pdf",485557,18,"English","# Abstract\n## Background\n## Method\n## Result\n## Conclusion\n# Author summary\n# Introduction","[{\"question\":\"What system was developed in the study?\",\"answer\":\"A decision-making support system for schistosomiasis transmission prevention and control during large-scale events, integrating risk identification, risk assessment, risk management strategies, and effectiveness evaluation.\"},{\"question\":\"How were risk levels determined?\",\"answer\":\"Risk indicators were established using literature review and the Delphi method, and risk levels were determined using Delphi consensus together with a risk matrix.\"},{\"question\":\"How was the effectiveness of interventions evaluated?\",\"answer\":\"Effectiveness was verified by monitoring schistosomiasis-related public health incidents and tracking key indicators over 1–3 years after events, with repeated risk assessments.\"}]","Evidence-based decision-making support for determining the risk of schistosomiasis infection during large events in China - Application of risk assessment | PDF",1790773552,45]
