F is for Flu: How Do Influenza and RSV Interact? | The A-Z of RSV
RSV and influenza circulate across the world every year. But what happens when these two respiratory viruses meet at the population level? In this episode of The A–Z of RSV, host Marta Nunes speaks with mathematical modeller Matthieu Domenech de Celles about the relationship between influenza and RSV. They explore why RSV and influenza epidemics occur when they do, how population immunity, human behaviour and weather contribute to seasonality, and what emerging research tells us about interactions between the two viruses. Matthieu explains how mathematical modelling can help researchers investigate whether infection with one virus can temporarily influence susceptibility to another and how these interactions may shape epidemic patterns. The conversation also considers why these interactions could matter for surveillance, forecasting and prevention, and why studying respiratory viruses as part of an interconnected system may provide insights that cannot be gained by looking at each virus in isolation.
