The basal body temperature in children is 36.9°C to 37.3°C. Generally, when the body temperature exceeds the basal body temperature, it can be considered feverish, and a fever of more than two consecutive weeks is called prolonged fever.
Fever is only a protective mechanism of the human body, which is an inflammatory response of the body to fight against bacteria and viruses when the body is invaded by pathogenic bacteria, and a complete return to normal temperature requires identification of the cause. The common cause of recurrent high fever in children is infectious diseases, including bacteria, viruses, mycoplasma, etc. can cause recurrent fever, need to combine with the baby’s other performance to check the blood routine, targeted to do some pathogenic aspects of the examination, combined with the results of targeted treatment of this recurrent fever can be completely relieved. There are also some rare pathogens such as tuberculosis, brucella, etc. can also cause recurrent fever in babies, and should be considered when the effect of conventional anti-infection is not good. There are also some non-infectious diseases such as Kawasaki disease, immune diseases, malignant diseases, etc. that can also cause recurrent fever and need to be clearly diagnosed with the appropriate tests chosen for each case.
During fever, when the temperature exceeds 38.5°C, timely administration of ibuprofen or acetaminophen to reduce fever for 3 to 5 days will not cause major damage to the child. However, the two antipyretic drugs must be given 4 to 6 hours apart.
