Vigorous hand washing is the cheapest and easiest means to prevent the spread of disease. Regular hand washing with soap and water can prevent the spread of many diseases, including the common cold, flu, and stomach viruses. It is a simple and effective way to protect oneself and others from infections. Pasteurizing milk, filtering air in tuberculosis rooms, and exposing operating rooms to ultraviolet light are also important measures to prevent the spread of disease, but they may not be as easy or cost-effective as hand washing.
