This is Scientific American's 60-Second Science,I am Karen Hopkin.This'll just take a minute.

 If you’re a fan of bad movies, and even if you’re not, you might remember the summer thriller¹ Snakes on a Plane. In it, gangsters² attempt to take down a plane by stuffing the cargo³ hold with angry venomous snakes. The movie probably didn’t make you fear getting bitten by a cobra on your next cross-country flight. But I’ll bet there is a critter you don’t want to encounter in coach. A creature so insidious⁴ that even shoving Neosporin up your nose won’t save you. I’m talking about germs. Admit it. When that guy four rows ahead of you starts hacking⁵, you can almost see the viruses wafting⁶ your way. But a study published in the March issue of the Annals of Industrial Hygiene⁷ suggests that you needn’t fear the microbes on your next flight. The scientists took air samples from a dozen planes at various times during flight. They found bacteria were most plentiful⁸ during boarding and deplaning. But the bugs⁹ they detected were mostly those found on the skin or in dust or outdoor air, probably stirred up by people moving around, getting in and out of their seats. So relax, take off your surgical¹⁰ mask and enjoy the in-flight movie. Unless, of course, it’s Snakes on a Plane.

Thanks for the minute,for Scientific American's 60-Second Science,I'm Karen Hopkin.
