Just the Facts: Pandemic Influenza Fact Sheet for Leaders   [open pdf - 41KB]

"Pandemic influenzas are extremely contagious viruses that may spread quickly throughout the world causing illness and death even among generally healthy groups such as military personnel. During the 20th century, the emergence of new influenza A viruses caused three pandemics, all of which spread around the world within one year of being detected. The most severe of these was the 1918-19, 'Spanish flu,' [A (H1N1)]. More than 500,000 people died from the Spanish flu in the United States, and 20- 40 million people died worldwide. U.S. military operations in World War I were impacted as 48,000 U.S. military members died from this influenza and subsequent pneumonias. Many people died within the first few days after infection, and others died of complications later. Nearly half of those who died were young, healthy adults. The U.S. Centers for Disease Control and Prevention (CDC) has estimated that within a 3 to 4 month period of the pandemics first wave, the U.S. could have up to 200 million cases with 800,000 hospitalizations and 300,000 influenza-related deaths. Age groups and geographical areas not affected by the first wave are often vulnerable during the second wave pandemic wave months after the first wave. In the past, the second wave has also been more severe."
