Most cold viruses are spread by contact with surfaces through "self-inoculation" when hands pick up cold viruses, and then touch the nose or eyes to start an infection. In fact, a study of kids showed that a program to discourage touching the face reduced colds by nearly half.

Studies show that maintaining a healthy body weight with proper nutrition reduces risks of infection, and also may prevent inflammation (potentially damaging immune system hyperactivity).

Cold viruses can be found in nasal secretions of children for two to three weeks after the onset of symptoms. That's a long time for an unwanted guest to stick around!

Colds are most infectious during the first two to four days people are infected. And you can't outrun their germs: droplets from sneezes can travel at a velocity of 45 miles per hour and cover a distance of 10 feet. Wash your hands and face regularly; when soap and water is not available use Wet Ones^® wipes to kill bacteria on your hands.
