这儿的school board昨晚发给家长的病毒性肺炎的预防措施，好像比较简单

Take the following usual precautions to reduce the risk of transmission of the flu and respiratory illnesses;

• Clean your hands often with soap and water or use hand sanitizer.
• Cough and sneeze into the bend of your arm, not into your hand.
• Avoid touching your nose, mouth or eyes with your hands.
• Clean objects and surfaces that a lot of people touch, such as doorknobs, phones, and television remotes.
• Get your influenza vaccine.
• Stay home when you are sick and avoid contact with other people until your symptoms are gone. Notify the school of your child’s absence.
