Everyone knows about the Black Plague in Europe during the Middle Ages. But not everyone knows about the 1918 influenza pandemic. It was the worst virus that ever struck mankind. Not even the Black Death comes close to the number of lives it took. No war, natural disaster, or famine has ever claimed so many people. From 1918 to 1919, one third of the global population (500 million) became infected, with an estimated 100 million deaths. This book chronicles the cause and impact of this deadly virus throughout history.
