No kidding! This CDC photograph captured a sneeze in progress, revealing the plume of salivary droplets as they are expelled in a large cone-shaped array from this man's open mouth. The flu virus can spread in this manner and survive long enough on a doorknob or countertop to infect another person. It dramatically illustrating the reason you should cover your mouth when sneezing or coughing to protect others from germ exposure, health officials say. It’s also why you need to wash your hands a lot, on the assumptions others don’t always cover their sneezes. Credit: CDC/James Gathany .From Live Science:
Best to do the sneezing inside a shuttle or the space station, not on a spacewalk, when it can get real messy, with goo sprayed all over the inside of the helmet's "windshield."
Lately astronauts have been complaining about stuffy heads up there on the International Space Station. NASA doesn't think they have colds, though. Rather, the effects have more to do with pockets of carbon dioxide generated when they gather in groups, space station flight controller Heather Rarick said.
