150,000 bars of soap were given to schools in Ethiopia, where the Education Ministry asked 1,000,000 schoolchildren to wash their hands for the event.

　　Experts say people around the world wash their hands but very few use soap at critical moments such as after using the toilet, after cleaning a baby and before touching food.

　　The organizers say all soaps are equally effective at removing disease-causing germs(细菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least 20 seconds.

　　Then, wash your hands well under running water. Finally, dry your hands with a clean cloth or wave them in the air.

　　They say soap is important because it increases the time that people spend washing. Soap also helps to break up the grease(油脂) and dirt that hold most of the germs. And it usually leaves a pleasant smell, which encourages people to wash again.

　　They say washing with soap before eating and after using the toilet could save more lives than any vaccine or medicine. It could help reduce cases of diarrhea(腹泻) by almost half. And it could reduce deaths from pneumonia(肺炎) and other breathing infections by one-fourth.

　　Diarrhea is the second leading cause of child deaths, killing more than 1,500,000 children a year. Pneumonia is the leading cause, killing about 2,000,000 children under five each year. Hand washing can also prevent the spread of other diseases.
