All estimates are standardised according to the age structure of the respective country

^aAge-specific proportions of infected individuals hospitalised were taken from Verity et al. [18]. These proportions were adjusted for under-ascertainment and corrected for demography. We assumed that cases defined as severe would be hospitalised

^bAge-specific proportions of hospitalised cases requiring critical care were taken from Imperial COVID-19 Response Team Report [4]

^cAge-specific proportions of individuals requiring critical care die were calculated by dividing the IFRs with proportions of infected individuals hospitalised and proportions of hospitalised cases requiring critical care

^dAge-specific IFRs were taken from Verity et al. [18]
