Misleading claim circulates online about infection fatality ratio of Covid-19 in the US
Multiple Facebook and Instagram posts have shared a screenshot of a Fox News graphic that purports to show infection fatality ratios in the United States for the novel coronavirus, based on various age groups. The graphic was shared alongside a claim that there was "never a pandemic". The graphic, however, is not accurate and has been shared in a misleading context; Fox News said the figures were “shown in error” on air as percentages rather than ratios; a health metrics expert said the values aired by Fox News are not accurate.
The graphic was published on Instagram here on September 25, 2020.
The graphic from US television network Fox News purports to show the infection fatality ratio (IFR) for Covid-19 as percentages by age groups. It cites the U.S. Centers for Disease Control and Prevention (CDC) as its source.
The graphic reads: “INFECTION FATALITY RATIO, IF INFECTED
"0-19 years - .00003%
"20-49 years - .0002% "50-69 years - .005% "70+ years - .054%”.
The Instagram post’s caption reads in part: “The truth is that this has never been a pandemic nor has it ever been about protecting people’s health. Quite the opposite. This has been about fear, control, $$$ and a new vaccine.”
The graphic, however, is not accurate.
The values in the graphic appear to be taken from this page on the CDC’s website. It provides the current best estimates for the coronavirus’ IFR, which estimates the “proportion of deaths among all infected individuals,” as the World Health Organization notes.
The CDC’s figures, however, were inaccurately displayed by Fox. The CDC notes that the values are in fact ratios, not percentages, for the “number of individuals who die of the disease among all infected individuals (symptomatic and asymptomatic).”
In response to the misleading posts, a spokesperson for Fox News told AFP by email the percentage symbols in the graphic were “shown in error” during The Ingraham Angle, one of Fox’s nightly convervative opinion shows, on September 23, 2020.
Theo Vos, a professor of Health Metrics Sciences at the Institute for Health Metrics and Evaluation, also said the Fox News graphic was inaccurate.
In an email to AFP on October 2, 2020, Vos said the purported IFR percentages seen in the graphic are lower by “a factor of 100 than the IFR reported by CDC”.
