In these conditions, body temperature is elevated without a corresponding signal from the thermoregulatory pathways [16]. In contrast, fevers are elevations of body temperature that occur in conjunction with an increase in the hypothalamic set point [17].

Which is the upper limit of a fever?

He concluded that the temperature of a healthy person is maintained within a narrow range, rarely swaying more than 0.9°F from its baseline [8]. He also identified the upper limit of the range of normal temperatures in a healthy person as 100.4°F, and thus he defined a fever as any temperature above this threshold [8].

What is the cut off for a fever?
