How many people die after being infected with the novel coronavirus? Fewer than previously calculated, according to a study released Monday, but still more than die from the flu. The research, published in the medical journal The Lancet Infectious Diseases, estimated that about 0.66% of those infected with the virus will die. That coronavirus death rate, which is lower than earlier estimates, takes into account potentially milder cases that often go undiagnosed -- but it's still far higher than the 0.1% of people who are killed by the flu. When undetected infections aren't taken into account, the Lancet study found that the coronavirus death rate was 1.38%, which is more consistent with earlier reports.
