“Worst case for a severe pandemic would certainly be in the millions [of deaths] in the U.S. alone,” says John Barry. He has advised the last two U.S. presidents on the flu virus and wrote The Great Influenza: The Epic Story of the Deadliest Plague in History. … When the so-called Spanish flu struck in 1918, it resulted in 500 million infections and 50 million to 100 million deaths, in a world with a population of about 1.8 billion people. That’s equivalent to around 385 million deaths—only a little less than the current population of South America—if extrapolated out to today’s population. “Because of the mildness of the 2009 pandemic, I would say most people underestimate the threat,” says Barry.
On a related note, Jeff Jarvis reminds us of the role data might play in preventing the next pandemic:
Google’s founders have urged government regulators not to require them to quickly delete searches because, in their patterns and anomalies, they have found the ability to track the outbreak of the flu before health officials could and they believe that by similarly tracking a pandemic, millions of lives could be saved. Demonizing data, big or small, is demonizing knowledge and that is never wise.
