Finally, some good news about airplane travel. If you are on a plane with a sick passenger, you are unlikely to get sick. That is the 26 of a new study that looked at how respiratory ( 呼吸道 ) viruses 27 on airplanes. Researchers found that only people who were seated in the same row as a passenger with the flu, for example — or one row in front of or behind that individual — had a high risk of catching the illness. All other passengers had only a very 28 chance of getting sick, according to the findings. Media reports have not necessarily presented 29 information about the risk of getting infected on an airplane in the past. Therefore, these new findings should help airplane passengers to feel less 30 to catching respiratory infections while traveling by air. Prior to the new study, litter was known about the risks of getting 31 infected by common respiratory viruses, such as the flu or common cold, on an airplane, the researchers said. So, to 32 the risks of infection, the study team flew on 10 different 33 in the US during the flu season. The researchers found that passengers sitting within two seats on 34 side of a person infected with flu, as well as those sitting one row in front of or behind this individual, had about an 80 percent chance of getting sick. But other passengers were 35 safe from infection. They had a less than 3 percent chance of catching the flu.
