Seasonal flu kills on average 0.1% of people who become infected according to the New York Times.
(New York Times) “On average, seasonal flu strains kill about 0.1 percent of people who become infected. The 1918 flu had an unusually high fatality rate, around 2 percent. Because it was so contagious, that flu killed tens of millions of people.”
But if you divide the amount of deaths reported in Italy as of March.19th, 2020, by the total reported cases, you might be shocked to find out that coronavirus kills 8.3% of people that end up getting sick.
That makes it 83 times more deadly than seasonal influenza.
