Flu

These days, many students are absent from school because of flu and cold.
Club activities which are usually held after school were cancelled yesterday to avoid interactions among students and to stop spreading those diseases.
I took vaccination for flu because I care about my physical condition.
Hopefully, I will not catch flu this winter.
If a lot of students don’t come to school due to flu, classes will be canceled and students will not have to come to school.
Many students at school wear masks to prevent themselves from getting the disease.
I wish this situation won’t be worse anymore.
