This paper proposes a model that visualizes the risk of contact infection to family members when going outspreads to various items at home. Behaviour data after returning home are extracted from the behaviour survey, such as location and contact objects. Then data tables are created, including a behaviour history table, behaviour probability table, contact probability table, number of visits table, contact circulation table, etc. The material transmission rate table is created by measuring the virus transmission rate after contact with droplets in a virus experiment laboratory,
