In the 1918-19 Spanish flu pandemic, the death toll reached a staggering 20 to 40 million worldwide.
Declared a global pandemic in 2009, H1N1 cases have been noted in more than 205 countries, totaling more than 620,000 verified cases and leading to more than 8,000 deaths.

Maybe. U.S. health officials have estimated that up to 1.9 million Americans could be killed and nearly 10 million hospitalized by an avian bird flu pandemic.
Avian bird flu media reports have been filled with outbreak potential in recent weeks, with much press given to the threat of a pandemic, prompting President Bush to implement a plan to combat an outbreak of avian flu.

Diffusion.-At the outset it is characteristic of this subtle disorder that the present pandemic diffusion cannot be traced with certainty to a definite time or place of origin.
