A businessman’s post on Instagram and Facebook wrongly claims that the U.S. government “changed the definition of pandemic” in 2004, suggesting that COVID-19 would not have qualified under the old definition. There’s no evidence for those claims and COVID-19 is by all means a pandemic. How lethal is COVID-19?
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.
