At the client's request, we delivered a system for integrating, analyzing, and visualizing data on the presence of selected pathogens (SARS-CoV-2 virus, harmful substances) in sewage networks. The application features a specifically designed layer for graphical data presentation. This allows for the display of both basic analyses, such as data trends and their statistical properties, as well as a range of more advanced conclusions resulting from comparative analyses. The team's unique expertise in epidemiological and medical data modeling enabled the creation of a tool that sets new standards for the handling and utilization of such data for the epidemiological security of the country and regions.
