Respiratory Syncytial Virus (RSV) is the most common cause of respiratory infections in infants and young children. While RSV presents a significant health and economic burden both in Australia and internationally, its epidemiology is currently not well understood. We collaborate with Dr Hannah Moore from the Telethon Institute in Western Australia to fit mathematical models to linked data on childhood cases of RSV. Using models, we explore the drivers of RSV transmission, and the seasonal factors that influence its spread.
