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 (病毒) from many places and make yourself ill. You’re in danger 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 (传播) 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 toughing pets or other animals
●After visiting anyone who is sick.
