How can I prevent a cold?

Handwashing is the most effective way to prevent colds. If possible, one should avoid close, prolonged exposure to people who have colds. Daily diets should include foods such as fresh, dark-colored fruits and vegetables, which are rich in antioxidants that help support the immune system. Viruses causing the cold can survive hours on inanimate objects and skin. Therefore, cleaning household surfaces with antiviral disinfectant might also help prevent the spread of infection.

Is my cold contagious?
