The Great Influenza: The Epic Story of the Deadliest Plague in History

by John M. Barry

No medicine and none of the vaccines developed then could prevent influenza. The masks worn by millions were useless as designed and could not prevent influenza. Only preventing exposure to the virus could. Nothing today can cure influenza, although vaccines can provide significant—but nowhere near complete—protection, and several antiviral drugs can mitigate its severity. Places that isolated themselves—such as Gunnison, Colorado, and a few military installations on islands—escaped. But the closing orders that most cities issued could not prevent exposure; they were not extreme enough. Closing saloons and theaters and churches meant nothing if significant numbers of people continued to climb onto streetcars, continued to go to work, continued to go to the grocer. Even where fear closed down businesses, where both store owners and customers refused to stand face-to-face and left orders on sidewalks, there was still too much interaction to break the chain of infection. The virus was too efficient, too explosive, too good at what it did. In the end the virus did its will around the world.
