Son not feeling well in the morning

During recess time, son called me from school's teacher office. He told me he vomited in restroom around 10am. He says that he not able to go tuition in the afternoon so I get him after school, then he headed to nearest stationery shop, then asked me to purchase toy for him.

He's having his nap now, he says he wants to go Eye Level at 5pm, wait another half hour to wake him up.

My friend says now school's having Rotavirus, the children are getting and spreading not sure of which class. But I find out son's classmate got it 2 weeks ago before the exam start. My friend's daughter too, she started having fever.

We need to take care of their health, as nothing matters more than health.
