No

Doctor's answer:

Oral temperature exceeding 37.3°C, axillary temperature exceeding 37°C, rectal temperature exceeding 37.6°C, or a daily temperature fluctuation of more than 1°C can be considered as fever. Fever is generally divided into hyperpyrexia (body temperature above 41°C), high fever (above 38°C), and low fever (around 37-38°C).
