    According to the Center for Disease Control and Prevention (CDC) (疾病控制预防中心), if you don't
often wash your hands, you can pick up viruses (病菌) from many places and make yourself ill. You're at
risk every time you touch your eyes, nose or mouth. In fact one of the most common ways people catch
colds is by rubbing their noses or their eyes when there are cold viruses on their hands. If you don't often
wash your hands,especially when you're sick, you may spread the viruses directly to others. You should
wash your hands in the following situations:
    ●After using the bathroom.
    ●After blowing your nose or coughing. 
    ●Before eating, serving or preparing food. 
    ●After touching pets or other animals. 
    ●After visiting anyone who is sick. 
    ●When your hands are dirty. There's right way to wash your hands. Follow these simple steps to keep
your hands clean.
