We analysed the influenza epidemic that occurred in Australia during the
2022 winter using an age-structured dynamic transmission model which
accounts for past epidemics to estimate the population susceptibility to
an influenza infection. We applied the same model to five European
countries. Our analysis suggests Europe might experience an early and
moderately large influenza epidemic. Also, differences may arise between
countries, with Germany and Spain experiencing larger epidemics, than
France, Italy and the UK, especially in children.
