“Between June 1 and August 1, 200,825 British soldiers in France, out of two million, were hit hard enough that they could not report for duty even in the midst of desperate combat. Then the disease was gone. On August 10, the British command declared the epidemic over. In Britain itself on August 20, a medical journal stated that the influenza epidemic “has completely disappeared.”

“killed enough to depress the average life expectancy in the United States by more than ten years. Some of those who died from influenza and pneumonia would have died if no epidemic had occurred. Pneumonia was after all the leading cause of death. So the key figure is actually the “excess death” toll. Investigators today believe that in the United States the 1918–19 epidemic caused an excess death toll of about 675,000 people. The nation then had a population between 105 and 110 million, while it was approaching 300 million in 2006. So a comparable figure today would be approximately 1,750,000 deaths.”
