The cause is a virus that passes from one person to another. The virus spreads through the air when an infected person expels air suddenly.Flu develops
61、 after the virus enters a persons nose or mouth. The flu causes muscle pain, sudden high body temperature, breathing problems and weakness. Generally, most people feel better after a week or two.

But they did not really know why until recently.American researchers say they now know why the flu virus spreads in the winter and not in the summer. They say it is
63、because the virus remains in the air longer when the air is cold and dry.Researchers in New York carried out twenty experiments with guinea pigs to investigate how the virus spreads.

The researchers also found that the animals spread the virus among themselves nearly two days longer when the temperatu
65、re was low.One of the researchers said the study shows that flu virus is more likely to infect people during an outdoor walk on a cold day than in a warm room.
