If you have a question about this talk, please contact Dr Ciara Dangerfield .

Although there was widespread belief that dense contact networks within universities might facilitate rapid spread of SARS -CoV-2 amongst an unvaccinated population, the relative risk of infection during different activities of university members on and off-campus was unknown. We use linked saliva-based asymptomatic PCR testing and detailed contact survey data to explore whether contacts in different settings visited by university members may present higher risk for infection during September 2020-March 2021. We use a Bayesian approach to compare models for infection risk based on different definitions of contact and present a multiple component analysis demonstrating how the adoption of protective behaviours can vary by setting.
