Risk of death from COVID-19 doubles for approximately every eight years of aging. ...snip... Age-specific IFRs increased from 0.1% and below for individuals under 40 years to greater than 5% among individuals over 80 years
Using these age-specific estimates, the team estimates the overall IFR in a low-income country, with a population structure skewed towards younger individuals, can be expected to be approximately 0.23% (95% prediction interval 0.14-0.42).
In contrast, in high income countries, with a greater concentration of elderly individuals, the report estimates that the overall IFR can be expected to be approximately 1.15% (95% prediction interval 0.78-1.79).
