To,

The Principal

[School name & address]

Sub:-

I am writing to request a leave of absence from school due to a sudden onset of fever. I have been experiencing symptoms such as high temperature, body aches, and fatigue, and I believe it is best for me to rest and recover at home.

I am currently enrolled in (grade/year) and I am scheduled to attend classes for the next (number of days). However, due to my current health condition, I will not be able to attend classes during this period.

I would like to request a leave of absence from (start date) to (end date) to allow me to fully recover from my illness. I assure you that I will do my best to keep up with my studies and catch up on any missed coursework once I have fully recovered.

Thank you for your understanding and consideration in this matter. Please let me know if you require any additional information or documentation from my parents or medical provider.

Sincerely,

[Your Name]
