Where did the epidemic start?

From the www.Fold3.com Blog -
"Though commonly called the Spanish flu (because of a highly publicized outbreak in Spain), it likely began in Haskell, Kansas, where it spread to Camp Funston and from there to the rest of the world. Wartime conditions, like troop movements and overcrowded cantonments, accelerated and aggravated the spread of the virus, which proved to be much deadlier than the normal flu, in part because of a particularly tough strain of pneumonia that often accompanied it."
