Smallpox - 30% mortality. The modern smallpox vaccine was not developed until 1796, by which point the Revolutionary War was over, Tibilo. The precursor method was to infect patients with a less lethal type of the disease, but that was very much a disputed approach given the substantial adverse consequences that invariably came from doing so.

Chinese flu - 0.03% mortality rate for those under age 40 - lower than the flu.
Washington ordered the controversial inoculation against smallpox only because 25% of his army was infected and gravely ill, and where approximately 90% of the deaths arose from disease, not battle.

Did I miss something - are 90% of deaths in the United States due to the Chinese flu? Is the Chinese flu currently debilitating the army?
As usual, you repeat some idiotic, moronic, false point from Media Matters, too stupid to research the truth.
