Re: Spanish Flu morbidity rate of 8% to 20%
In the USA, morbidity was 2.5%.
The USA infection rate was 30%, which was the world average.
From memory, about 30 million Americans were infected, and about 750,000 died.
This happened under Woodrow Wilson's presidency, not even Franklin D. Roosevelt controlled the press and the release of information as tightly. Any statistics from that time period should be highly suspect. Even so you make a valid point.
