【答案】Dear fellow students，
Recently，many students in our school have asked for sick leave because of the flu.The lessons of one class even have been suspended for a week.If not dealt with properly，this infectious disease may seriously affect our normal life.
The Student Union would like to remind you that you need to wash your hands with liquid soap often and air/ventilate your classroom and dormitory frequently.Besides，it may also be helpful to drink more water and keep taking moderate physical exercise.
Wish all of us good health and all the best.
The Student Union
