     New York-Wednesday, October fifteenth, is the first Global Hand Washing Day. Activities are

planned in more than twenty countries to get millions of people in the developing world to wash their

hands with soap.

     Experts say people around the world wash their hands but very few use soap at so-called critical

moments. These include after using the toilet, after cleaning a baby and before touching food.

     Global Hand Washing Day is the idea of the Public-Private Partnership for Hand Washing with Soap.

The goal, they say, is to create a culture of hand washing with soap. The organizers say all soaps are

equally effective at removing disease-causing germs (病菌). They say the correct way to wash hands 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. Then, rinse well under running water. Finally, dry your hands with a clean cloth.

     The Partnership says soap is important because it increases the time that people spend washing.  

Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell,

which increases the likelihood that people will wash again.

     It also says washing with soap before eating and after using the toilet could save more lives than any

medicine. It could help reduce cases of diarrhea (痢疾), which is the second leading cause of child

deaths, killing more than one and a half million children a year, by almost half.
