Health Tip: Avoid the Common Cold
Wash your hands frequently
(HealthDay News) -- There really is no foolproof way to prevent the common cold.
But one of the best ways to avoid it is to wash your hands -- before eating, when preparing food, even after using someone else's phone at work.
According to the U.S. National Institutes of Health, colds can occur any time of year, but they mostly affect people during winter.
When someone has a cold, their nose is teeming with a virus that is spread when they cough, sneeze or touch something.
People are most contagious during the first two or three days of a cold, the agency says.
