Asgary led the study in collaboration with Professors <strong>Shengyuan Michael Chen<\/strong> and <a href=\"https:\/\/news.yorku.ca\/experts\/?name_or_keyword=jianhong+wu&amp;research_area=&amp;submit=Search+the+Guide&amp;search=Y\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>Jianhong Wu<\/strong><\/a> of the Faculty of Science\u2019s Laboratory for Applied and Industrial Mathematics (<a href=\"https:\/\/liam.lab.yorku.ca\/\" target=\"_blank\" rel=\"noopener noreferrer\">LIAM<\/a>) and Professor <strong>Monica Gabriela Cojocaru<\/strong> of the University of Guelph's\u202fDepartment of\u202fMathematics and Statistics.<\/p>\n<p>\u201cAs the reopening of schools may create conditions for further spread of the virus and increase case numbers in schools, as well as in the community, testing could help prevent large outbreaks while allowing students to learn onsite at schools,\u201d says Asgary.<\/p>\n<p>Cojocaru, a co-author on the paper, says \u201cWe know that\u202fschool closures hurt everyone \u2013 children, parents, teachers, the economy.\u202fWe need\u202fto use\u202ftesting\u202fas a tool in this fight, but we need to have a strategy for that testing. That\u2019s what this study\u202faimed to propose.\u201d<\/p>\n<p>The researchers at York also developed an agent-based model and simulation tool, a school testing application, that can analyze the outcomes and effectiveness of different testing strategies and scenarios in schools. It can be used to analyze various numbers of classrooms and differing class sizes.<\/p>\n<p>\u201cIt could be an important additional preventative tool to ensure early identification of cases among students,\u201d says Wu. \u201cThe school testing app allows users to define disease-related parameters and their school settings, as well as predict and assess the impacts of different testing strategies.\u201d<\/p>\n<p>The goal is to test a random number of students once a day from every class. Any students who test positive would go into self-isolation at home. The tool includes options to test the entire classroom or to have all students in a class, where someone tested positive, to self-isolate. The study\u2019s base model looked at a school with 20 classes and 25 students in each class for 60 days.<\/p>\n<p>Whether to test or not in schools has become an important policy and planning issue for school reopening both following the summer and the winter holiday break. Simulation modelling and artificial intelligence can help with exploring and examining the impacts of different testing scenarios.<\/p>\n<p>The paper, <a
