Official Leave Letter for Fever
(Address of the Company)
With due respect and honour, I am writing this letter to request an extension for my illness leave for medical reasons. I have been suffering from fever since (date…….). I appointed to the doctor and he has suggested 5 more days complete bed rest. I would not be able to attend office from (date……) 2014. I can provide you my medical certificate and other official documents. I will try my level best to compensate the delay at work as I will be back from my illness leave.
Thank you so very much for your kind consideration.
