How Can I Prevent It?

A strong immune system is the best defense against all infections, colds included. It may not keep you from getting infected, but you'll recover more quickly. Boost your body's natural resistance by eating well, not smoking, and drinking plenty of water every day.

Minimize contact with people who have colds. Don't share towels, silverware, or beverages with them. Cold viruses often survive for hours in the open, on doorknobs, on money, and on other surfaces. Wash your hands frequently and properly.

When you have a cold, do your best to keep it to yourself. A hearty sneeze can carry your cold virus up to 12 feet away, so always cover your mouth with a tissue when you sneeze or cough. If you sneeze or cough into your hand, your hand can transmit the infection -- so wash up.
