How to write leave letter to School Principal Due to Fever in English

The Principal
Daffodils High School

Subject: Application for one day leave due to fever.


With due respect, I would like to state that I have high fever since morning. My mother has called our family doctor for diagnosis and treatment. Hence I am unable to attend my school classes today.

Kindly grant me leave for one day. I would be very thankful for your consideration.

Yours faithfully
