There has not been a worldwide spread (傳播) of flu (流行性感冒) since 1968. Experts say there should have been another by now. The so-called Spanish flu in 1918 became the most deadly flu ever recorded. It killed an estimated twenty million to fifty million people. Almost half were young adults. There were two other widespread flu in the twentieth century. The Asian flu struck in 1957, and the Hong Kong flu in 1968. Scientists at the United States Centers for Disease Control and Prevention say the cause of the widespread Spanish flu is not clear. But the two others are known to have resulted from a human virus that became mixed with a bird flu virus. And that could happen again. Scientists first identified bird flu in Italy more than one hundred years ago. Bird flu is caused by type A flu viruses. Type A are the most common, and usually cause the most serious flu spread in people. Currently the most serious kind of bird flu is known as h-five-n-one.
