Its clinical significance is commonly seen in acute infectious types of diseases, such as lobar pneumonia, spotted fever, and typhoid fever during the hyperthermia period.2 Flaccid fever, also known as septic fever, is usually above 39°C, but the fluctuation range is relatively large, and usually fluctuates by more than 2°C within 24 hours, and is seen in sepsis, rheumatic fever, and severe tuberculosis.3 Fluctuating fever refers to the gradual increase in body temperature to reach above 39°C. It can also be characterized by a gradual increase in body temperature. And then after a few days and gradually decline to the normal level, continued for a few days and rise, so repeated multiple cycles, common in some infectious diseases, such as brucellosis. 4, intermittent fever refers to the body temperature suddenly rise and then suddenly fall in acute pyelonephritis, malaria and other diseases. 5, return to the heat is uncommon, refers to the body temperature rises sharply 39 ℃ above the level of the last few days and then fall to the normal level, after several days of regular alternation, the body temperature will rise to the normal level, and after a number of days, it will fall to the normal level.
