The range value of low fever is 37.3℃-38℃. Symptoms of intermittent low fever are usually considered to be caused by diseases, such as colds and tonsillitis, which can cause intermittent low fever and are easily recurring. Pneumonia, if the symptoms are not relieved, may also present intermittent low fever. There are also serious diseases such as measles, meningitis, etc. The use of antipyretic drugs can only improve the symptoms because antipyretic drugs do not have antibacterial and antiviral abilities, so the fever subsides after taking the drug, and once the effect of the drug has passed, the temperature slowly rises again and the fever is repeatedly low. In case of recurrent low fever, it is recommended to seek medical attention at an offline hospital to clarify the cause and give targeted treatment.
