The Flu That Shook the World

　　In 1918, Americans were at war. They were fighting World War I in Europe. They were also fighting the flu(流行性感冒) .

　　The flu was a dangerous enemy. It spread quickly and it killed quickly. Soldiers lived close together. They caught the flu from each other. About 112000 American soldiers died in World War I . More than half of these soldiers died from the flu.

　　Many soldiers from other countries died also. Mast countries kept their flu deaths a secret. Spain did not, so the flu became known as the “Spanish flu. ”

　　American soldiers brought the flu home with them. It swept across the country in 1918. There weren't enough doctors and nurses to go around. All together, 500000 Americans died of the Spanish flu.

　　Today, the flu is still our enemy. During flu season, many people get sick. Some even die. Babies and old people are in special danger. They can get help, though. Doctors can now fight the flu with flu shots.

　　The fight against the flu still goes on. Now we are winning the fight. The great flu of 1918 should never happen again.
