On Sunday, the head of the U.S. Food and Drug Administration (FDA) declined to criticize President Donald Trump’s unfounded claim that 99% of COVID-19 cases are “totally harmless.” As the United States neared 130,000 deaths from COVID-19 this Independence Day weekend, Trump asserted at a speech yesterday that the U.S. has tested 40 million people and that 99% of cases are “harmless.” The President’s claim contradicts the existing data, including estimates by the Centers for Disease Control of the number of asymptomatic patients and evidence that this group can actively transmit the disease.
