1918 influenza pandemic

In 1918, a virus spread across the planet -- unstoppable, incurable. In Baltimore, the impact was shocking. And as World War I was coming to an end, a new battle was shaping up in homes, schools and neighborhoods. By the end of October the virus had claimed more than 3,000 Baltimoreans. By spring it had killed an estimated 50 million people worldwide -- 650,000 of them Americans. Nearly a century later, the people who lived through it and the victims' families still recall their experiences with the flu.
