A study that looked into the age-stratified infection fatality rate (IFR) of COVID-19 among the non-elderly population has found that the rate was extremely low among young people.
“The median IFR was 0.0003 percent at 0–19 years, 0.002 percent at 20–29 years, 0.011 percent at 30–39 years, 0.035 percent at 40–49 years, 0.123 percent at 50–59 years, and 0.506 percent at 60–69 years,” the study conducted across 29 countries stated. “At a global level, pre-vaccination IFR may have been as low as 0.03 percent and 0.07 percent for 0–59 and 0–69-year-old people, respectively.”
The study aimed to accurately estimate the IFR of COVID-19 among non-elderly populations in the absence of vaccination or prior infection.
For every additional 10 years in age, the IFR was observed to increase by roughly four times. After including data from nine more nations, the median IFR for 0–59 years came in at 0.025 to 0.032 percent and for 0–69 years was at 0.063 to 0.082 percent.
According to the study, the analysis suggests a “much lower” pre-vaccination IFR in the non-elderly population than had been suggested previously. The large differences found between nations were pegged to differences in factors like comorbidities.
