Snippet: The age structure of affected population should be also accounted for a fair comparison. In Korea, the low CFR, 1.3% as of March 25, 2020, could have resulted from the larger proportion of younger confirmed cases resulting larger denominator of low-risk population. Difference in age structure of affected population between countries may guide to the true burden of COVID-19 in terms of disease severity and fatality proportions. Age-specific or age.....
Document: The age structure of affected population should be also accounted for a fair comparison. In Korea, the low CFR, 1.3% as of March 25, 2020, could have resulted from the larger proportion of younger confirmed cases resulting larger denominator of low-risk population. Difference in age structure of affected population between countries may guide to the true burden of COVID-19 in terms of disease severity and fatality proportions. Age-specific or agestratified CFR will be useful in comparing between the countries with different affected age groups. difference between the two countries sharply decreases among the individuals older than 70. Thus, taking the age structure of confirmed cases into account is crucial for a fair comparison as it shows the difference in the age-adjusted CFR between the two countries is considerably reduced (2.4% vs. 4.2%).
