The global flu outbreak of 1918 killed 50 million people worldwide, ranking as one of the deadliest epidemics in history.
For decades, scientists have debated where in the world the pandemic started, variously pinpointing its origins in France, China, the American Midwest, and beyond. Without a clear location, scientists have lacked a complete picture of the conditions that bred the disease and factors that might lead to similar outbreaks in the future.
The deadly "Spanish flu" claimed more lives than World War I, which ended the same year the pandemic struck. Now, new research is placing the flu's emergence in a forgotten episode of World War I: the shipment of Chinese laborers across Canada in sealed train cars.

Memorial University of Newfoundland says that newly unearthed records confirm that one of the side stories of the war—the mobilization of 96,000 Chinese laborers to work behind the British and French lines on World War I's Western Front—may have been the source of the pandemic.
