We have previously documented that the UK case-fatality rate (CFR) has fallen substantially from its peak in April. One explanation is that, unlike in March and April, new cases are predominantly in younger people who have a better outcome.
We, therefore, sought to examine trends in CFR over time to see if the fatality rate was declining across all age groups.
Due to the absence of age-stratified case data in the UK (although we’re working on this) we have used German data which reports lab-confirmed cases and deaths by broad age categories.
This analysis shows that the fatality rate from COVID-19 has declined in all age groups, and the older age groups drive the overall reduction.
