Kuumeeton

Kuumeeton is a Finnish term used in medical contexts to describe a presentation without fever. It refers to a clinical state in which a patient does not meet the common criteria for fever, even if other symptoms of illness are present.

Definition and usage

In Finnish clinical language, kuumeeton describes a patient whose body temperature remains below the usual fever threshold. Fever is often defined in adults as a body temperature around 38.0°C (100.4°F) or higher, but exact cutoffs can vary by source and measurement method. A fever can be influenced by factors such as the measurement site (oral, tympanic, axillary), time of day, and use of antipyretic medications, which may mask fever and contribute to a kuumeeton presentation.

Clinical implications

Kuumeeton presentations can complicate diagnosis because fever is a common sign of infection and inflammation. Certain patient groups, particularly older adults, the very young, or people with weakened immune systems, may not develop a fever even in the presence of infection. Therefore clinicians may rely on other signs, laboratory tests, and imaging to identify underlying causes when fever is absent. Afebrile infections can include respiratory or urinary tract infections, among others, but the absence of fever does not rule out serious illness.

Etymology and context

The term combines kuume (fever) with a suffix meaning without. It is used in patient histories, case reports, and guidelines to describe a symptom profile lacking fever, guiding differential diagnosis and assessment.
