What Celsius temperature defines fever?

• A. 37 C
• B. 38 C
• C. 39 C
• D. 40 C

Answer: (B)

Fever is defined by a measured body temperature that rises above the normal range. Clinically, the threshold used is 38°C or higher, so a temperature at or above 38°C is considered fever. Normal body temperature is around 36.5–37.5°C, with 37°C often cited as a typical average; thus 38°C marks a clear elevation rather than ordinary variation. Values like 39°C or 40°C are also fevers, but they represent higher degrees of fever rather than the standard threshold. A reading of 37°C is not fever.
