FACT BRIEF

Do both excess-death estimates and case fatality rates show that COVID-19 has been far more deadly than the flu?

YES

COVID-19’s deadliness is tracked in two ways. Measures of “excess” deaths vs. historical averages are used as fatal cases are not always identified by tests. “Case fatality rates” tally officially reported fatal cases of the disease. Both measures suggest COVID-19 has been far more deadly than ordinary flu.

Flu epidemics vary in severity from year to year, and with incomplete testing data excess-death numbers are particularly helpful. A review of a decade of flu data from the Netherlands found only one period with excess deaths even close to comparable to those from an eight-week period last year during the initial outbreak of COVID-19.

The Centers for Disease Control estimates that the fatality rate from flu in the U.S. in the 2017-18 winter season was 0.13% (61,000 deaths). The case-fatality rate of COVID-19 to date in the U.S. is 1.8% (561,000 deaths).

ABOUT THE CONTRIBUTOR
Gigafact
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
