A study shows that one million lives might be saved each year if people wash their hands with soap(肥皂) often. It also says that hand-washing with soap could be among the best ways to reduce diseases. Doctors say many diseases can be prevented from spreading by hand-washing. These include the common cold, influenza(流行感冒), hepatitis(肝炎), infectious diarrhea(腹泻) and so on.
Doctors say you are easy to catch a cold by touching your nose or eyes after someone nearby has sneezed or coughed. Another reason to catch a disease is to eat food prepared by someone whose hands were not clean.
They also say that hand-washing is especially important before and after preparing food, before eating and after using the toilet, after touching money and sneezing or coughing. The most helpful way is to wash them together while using soap and warm water. You do not have to use special soap. Be sure to wash all areas of the hands for about ten to fifteen seconds.
