Estimates of the impact of changing contact patterns due to COVID-19 restrictions on norovirus A incidence and B susceptibility to symptomatic infection from January 2019 to June 2023. In each panel, each colour represents simulations that assumptions contact patterns after July 2021 are the same as pre-COVID-19 (light red) or adults have 80% fewer contacts (red), and allowing for different assumptions about under-reporting of norovirus incidence within Harris et al. [31]; solid lines assume no under-reporting and dashed lines assume 20% underreporting. UP under-reporting, sim simulated duration of asymptomatic infectiousness in days
