A tipping point of spreading viruses: Estimating the risk of household contact transmission of COVID-19

COVID-19 infection has been reported to be caused by droplet and contact infection. This paper proposes a model that visualizes the risk of family members when viruses spread various items at home. Behavior data after returning home are extracted from questionnaire-based survey behavior design agent-based model. The tables created, including room-to-room transfer probability table, conditional table. material efficiency table is also created measuring virus transmission rate with droplets in experiment laboratory. In experiment, synthetic agent acquired probabilistically performs movement reproduces state which attached hand or belongings, going out, propagates objects Next, we examine second member As result, virus-attached contacts within around 30 minutes widely confirmed entrance kitchen, suggesting effectiveness early hand-washing behavior. And shows even if first person disinfects their hands inside entrance, remains part room
