PolitiFact's ruling: Half True Here's why: There’s no question the COVID-19 pandemic is one of the deadliest events modern Americans have ever grappled with. But how its death toll compares with other tragedies and natural disasters is being misconstrued in a social media post that purports to list and rank the "deadliest days in American history." The graphic shows that four of the eight deadliest days since the country’s founding took place between Dec. 2 and Dec. 7, 2020. The image places daily COVID-19 deaths from those days alongside death tolls from the Galveston Hurricane, the battle of Antietam, Pearl Harbor and the 9/11 terrorist attacks.
