““The pandemic may have originated in the American military post at Fort Riley, Kansas, where a dust storm whipping about tons of incinerated manure had sent hundreds of coughing, stumbling doughboys diagnosed with influenza into the post hospital, where many died. Soon after, American troopships disembarked at Brest and Saint-Nazaire, and French poilus began to fall ill, then British soldiers. Then, as the malady rolled across France, German troops were stricken. The fatality rate was appalling. In the AEF, roughly one out of every three soldiers with influenza died, far worse odds than a man faced in battle.””
