2、he episode was not significantly deadlier than a typical had fin season. Few people who lived through it even knew it occurred. Still, it killed 34,000 Americans. The 1918 pandemic was far more lethal. It killed 675,000 Americans at a time when the U.S. population was 100 million. Fifty million to 1

3、00 million people purished worldwide in the 1918 pandemic, according to Nobel laureate F. Macfarlane Burnet. The flu killed more people in 24 weeks than AIDS has killed in 24 years. The difference in the death toll between 1918 and 1968 had little to do with such medical advances as antibiotics for

4、secondary bacterial infections. The 1968 virus was simply much less virulent. But it wasnt just the virus. As with Hurricane Katrina, some of the deaths in 1918 were the governments responsibility. Surgeon General Rupert Blue was his days Mike Brown. Despite months of indications that the disease wo

5、uld erupt, Blue made no preparations. When the flu hit, he told the nation, “There is no cause for alarm.“Alarm was needed. Victims could die in 24 hours. Symptoms included bleeding from the nose, mouth, ears and eyes. Some people turned so dark blue from lack of oxygen that an Army physician noted

They also destroyed trust in authority, as Americans quickly realized they were being lied to. The result: society began to break apart. Confidential Red Cr

7、oss reports noted “panic akin to the terror of the Middle Ages of the plague“ and victims starving to death “not from lack of food but because the well are afraid to help the sick.“ Doctors and nurses were kidnapped. One scientist concluded that if the epidemic continued to build, “civilization coul

8、d easily disappear from the face of the earth within a few more weeks.“What will happen during the next pandemic.? No one can predict, but even a virus as mild as the 1968 strain would kill many tens of thousands in the U.S. alone. Since 1968, demographic changes have made influenza a greater, not a

9、 lesser, threat. Our population now includes more elderly and more people with a weakened immune system. The Centers for Disease Control and Prevention (CDC) estimates that influenza kills 36,000 Americans in an average year. The CDC also calculates that a pandemic caused by a virus comparable to th

10、at of 1968 would kill between 89,000 and 207,000 Americans. And the scientist who prepared that study has refused to estimate the toll from a more virulent virus because, he says, he doesnt want to “scare“ people.Even the mildest virus would slam the economy harder now than at any time in the past.
