Early in the morning, the phone in the office rang, and the parent on the other end of the line sent a message that her child had vomited in the middle of the night and needed to take the day off. A few minutes later, the phone rang again, and again, the child was vomiting in the middle of the night and had a fever, so she had to take the day off from work. Maybe it is because of the seasonal change, recently there are more children with gastrointestinal discomfort, vomiting, fever and sickness, some of them have symptoms at home, and some of them have conditions in kindergartens, such as stomach ache and vomiting, so parents will be asked to take their children home to rest and take care of them.
