Are child and youth population at lower risk of COVID-19 fatalities? Evidences from South-East Asian and European countries

•The preparedness to cope up with COVID-19 is lacking in SE Asian countries.•The SE Asian countries have more child and youths than European countries.•The CFR is higher in European countries than SE Asian countries. The coronavirus disease (COVID-19) pandemic has revealed many lacunas of public health preparedness, especially in lower and middle-income countries and fatality differentials between European and South-East Asian countries. The case fatality rate (CFR) in most of the South-East Asian countries is much lower than the European countries. The percentages of child and youth population are more in South-East countries. The study aims to show the impacts of age composition on fatality differentials in European and South-East Asian countries by age-structure, especially the percentage share of child and youth population. This study has been done based on data provided by UNDP, WHO and worldometers. The case fatality rate (CFR) has been calculated to find out the mortality differentials of countries, and the higher fatality risk countries have been identified by the composite Z score technique. It is revealed that the COVID-19 case fatality rates are substantially high in highly developed countries of the European countries compared to the South-East Asian countries. Our study shows that there is an issue of child and youth population which affects the lower CFR in SE Asian countries. In France, the CFR was 16.72% which was nearly 7 times more than India (2.31%). The COVID-19 fatality risk ratio was highest in Germany (0.77) while the lowest risk ratio was observed in Bangladesh (−0.71). Despite of having a very high level of human development and preparedness, the current pandemic COVID-19 has revealed that there exist significant differentials among fatality status of European and South-East Asian countries. The CFR is lower in the SE Asian countries where the child and youth population are more than the older population.
