The case fatality rate, or CFR, is the percentage of deaths from the coronavirus among the confirmed cases. According to a report by FactCheck.org, while the case fatality rate has fallen substantially since April, the decline cannot be attributed to improvement in treatments. While improved protocols for ventilator use for people with severe viral pneumonia, and the availability of drugs like remdesivir and dexamethasone have improved outcomes, a shift in the age distribution among those infected with an increasing number of lower-risk younger people testing positive and more widespread testing picking up mild or asymptomatic coronavirus cases, have played a bigger role in bringing down the CFR, the report found.
