Had flu but did not go to doctor

Patient: Hi I am a student from Scotland and I have recently had the flu but didn’t attend the doctors so that I didn’t spread my germs to anyone else how do I receive a sick line as I need it for my college do I just ask my gp for one

Doctor: Hi. Thank you for writing to us.I think you are asking for sick leave?If you are, then you should see a Doctor. He should be able to help you with one. Also, get treated by using tablet Paracetamol to help you.You should recover in 7 days from the flu.All the best.
