(Sudden Illness during school hours)
(Name of the School)
Subj.: Application for leave from attending school
I am writing to you today regarding an urgent matter. I recently fell suddenly ill during school hours and was unable to continue with my normal class schedule. This illness occurred without warning and required immediate medical attention, as it put my health at risk.
In light of this situation, I would like to formally request a leave of absence from my classes to allow me the time to recover and recuperate. I understand that this is not a typical request, but due to the nature of this illness I feel it is necessary.
I appreciate your consideration of my request and thank you for your understanding in this matter.

(Sickness before going to school)
Subject: Seeking leave from attending school due to sickness.
I am writing this letter to request for a leave of absence from school as I am not feeling well. I have been down with a fever since last night and I lack the energy to go to school. I am so sorry for informing you at such short notice but sadly there is no other way of letting you know.
I request that you give me a leave for one day and I shall get fully recovered before coming back to school. I will be extremely grateful if my request is accepted and I hope to return back to school tomorrow.

(Continued sickness after taking leave)
Subj.: Application for leave from attending school due to fever
I am writing to you today to request continued sick leave from school. As you may know, I have recently been diagnosed with a serious illness and will be undergoing treatment for the next several months. Unfortunately, this treatment requires that I stay at home during much of the day and rest as much as possible in order to recover.
I understand how difficult it will be for me to take so much time off from school, and I am deeply sorry for any inconvenience this may cause you or my classmates. However, your support in allowing me to recover fully is greatly appreciated. I look forward to returning to class as soon as possible, but in the meantime I know you will understand if I need to take more time off.
Thank you for your consideration, and I wish you all the best in the future.
