“ Over the past two and a half centuries, 10 to 20 human
influenza pandemics have swept the globe; the most
devastating, the so
-
called Spanish flu of 1918 to 1919,
caused more than 20 million deaths and affected more
than 200 million people. Both pandemics probably
originated from aquatic birds.”
