Fever
A fever is a higher than normal body temperature, usually around 98.6F / 36.5C. Most fevers are a sign of the body trying to fight an illness or infection, for example a virus or bacterial infection. A high temperature makes it harder for bacteria or a virus to survive.[1][2]
Prevalence[edit | edit source]
Symptom recognition[edit | edit source]
A low-grade fever is an optional symptom in the 1988 Holmes criteria for myalgic encephalomyelitis.[3]
Feelings of feverishness are recognized as a neuroendocrine system symptom in the Canadian Consensus Criteria.
An intermittent fever is a potential symptom of Long COVID in the World Health Organization's definition.[4]
In Japan, the so-called psychogenic fevers (a term that in modern times used almost exclusively in the Japanese medical literature)[5] (actually, hyperthermias) are a recognized symptom of ME/CFS.[6][7]
Notable studies[edit | edit source]
Possible causes[edit | edit source]
Most fevers are caused by an infection. Alternatively, autoimmune conditions and cancers can also present with fevers.
