It will take time to achieve herd immunity against SARS-CoV-2 through vaccination. In the meantime, we need to find ways to safely lift restrictions and resume economic and social activities while containing the virus. Therefore, indoors transmission of COVID-19 has been intensively researched since the beginning of the pandemic. There is an emphasis on quantifying viral transmission in areas with a high density of people. These high-risk spaces include healthcare clinics, schools, public transport, nursing homes and supermarkets. In this mini-symposium, we present several mathematical approaches for modelling the dynamics of transmission of COVID-19 in diverse indoor locations. All three main routes of transmission – airborne (through droplets and aerosols) and through surfaces (fomite) will be discussed and the effects of ventilation, antiviral technologies, and other non-pharmaceutical interventions will be presented. Deterministic and stochastic mathematical models are considered and are solved using a combination of analytical and numerical techniques. In many cases, Computational Fluid Dynamics simulations are employed to model air flows and transport of SARS-CoV-2 in detail. Many of these results have been used to inform policies related to the COVID-19 pandemic in the UK and elsewhere and the speakers comprise an interdisciplinary group from academic and government organisations.
