Fever is a high body temperature, usually defined as above 37.5 °C, but particularly when higher than 38 °C. It is normally caused by an infection. While it is not very serious in a previously healthy person, it is cause for transplant recipients, immunosuppressed patients and post-operative patients to visit emergency services.

Fever explained in first person

Professionals and patients explain how you live with the disease
Fever is very common. However, if the person has certain conditions, such as having an organ or bone marrow transplant, perhaps due to chemotherapy or if they recently had surgery or endoscopy, then they must go to A&E as soon as they get a fever.
