Understanding the Common Cold -- Prevention

How Can I Prevent the Common Cold?

A strong immune system is the best defense against all infections, common 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, getting adequate sleep, not smoking, and drinking plenty of water every day.

Minimize contact with people who have colds. Airborne droplets from sneezes or coughs are the most common mode of spreading this virus. Don't share towels, silverware, or beverages. Cold viruses survive for as long as 2 hours 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/. Cover your mouth when you cough and sneeze into your elbow. Your hand can transmit the infection -- so wash up.

A vaccine to prevent the common cold has been difficult to make, primarily because there are more than 200 different varieties of viruses that can cause colds.
