How do parents ask for leave when their children have a fever?

Tell the teacher about the child and explain the time of leave. When parents of children with fever take leave, they should get in touch with the child's class teacher in time, inform the teacher that the child can't go to school at present and needs to take leave, and indicate the time and period of leave. For example: hello, teacher, XX needs to take X days off because of fever. Thank you for your understanding and support.
