Recently, a famous Chinese actress from Taiwan died of pneumonia (肺炎) after catching the flu at the age of 48. The flu is a common illness that can make you feel very sick. It spreads easily, especially during colder months. There are several ways to protect yourself and others from getting the flu.

First, getting a flu vaccine (疫苗) every year is the best way to prevent the flu. The vaccine helps your body fight the virus. Doctors recommend that everyone over six months old get vaccinated.

Second, washing your hands often is important. Use soap and water, and wash for at least 20 seconds. If soap isn’t available, use hand sanitizer.

Third, avoid close contact with people who are sick. If you are sick, stay home to prevent spreading the flu to others. Cover your mouth and nose with a tissue when you cough or sneeze, and throw the tissue away immediately.

Finally, keep your body healthy by eating nutritious (有营养的) food, drinking plenty of water, and getting enough sleep. A strong body can help you fight off illnesses like the flu.

By following these steps, you can reduce your chances of getting the flu and stay healthy during flu season.
