Viral social media posts cite a flawed paper in falsely claiming the Centers for Disease Control and Prevention changed death certificate procedures and violated federal law, resulting in wildly inflated COVID-19 deaths. The CDC hasn’t altered how death certificates for COVID-19 are filled out, and there is no federal law governing the process.
It’s difficult to know exactly how deadly COVID-19 is, but as the World Health Organization has written, studies estimate that the infection fatality ratio, or percentage of deaths out of all infections, is between 0.5% and 1%. The true rate isn’t clear, since the pandemic is ongoing and not all infections have been diagnosed.
The case fatality rate, or percentage of deaths out of confirmed cases, was 1.8% in the United States as of March 31.
