Generally, a fever of 39.5°C in a six-month-old baby can be managed according to different causes, with common causes including bacterial infection, viral infection, and mycoplasma infection.
1. Bacterial infection
If the fever is caused by bacterial infection leading to dysfunction of the body's temperature regulation center and continuous elevation of body temperature, antibiotics such as amoxicillin capsules, ampicillin capsules, and phenoxymethylpenicillin sodium capsules may be used under a doctor's guidance.
2. Viral infection
If the fever is caused by a viral infection resulting in an elevated temperature set point of the thermoregulatory center, antiviral medications such as acyclovir capsules, ganciclovir dispersible tablets, and valacyclovir hydrochloride tablets may be used as directed by a physician.
3. Mycoplasma infection
If the fever is caused by mycoplasma infection leading to lung infection and stimulating body cells to produce pyrogens, medications such as cefaclor granules, azithromycin dry suspension, and roxithromycin tablets may be used under medical supervision.
In addition, antipyretics should also be used under the guidance of a doctor. Commonly used medications include acetaminophen oral solution, ibuprofen suspension, and ibuprofen granules. Furthermore, it could also be caused by diseases such as infection with the novel coronavirus, so it is recommended to follow medical advice for treatment.
