Introduction
High fever refers to a high body temperature. In a 9-month-old infant, recurrent fever that subsides and then rises again may be caused by upper respiratory tract infection, acute gastroenteritis, roseola infantum, otitis media, pneumonia, or other conditions, and can be treated through lifestyle adjustments and medication. Roseola infantum is an infectious disease caused by viral infection, commonly accompanied by symptoms such as high fever, rash, and malaise.

High fever refers to hyperthermia. In a 9-month-old infant, recurrent fever that subsides and then returns may be caused by upper respiratory tract infection, acute gastroenteritis, roseola infantum, otitis media, pneumonia, or other conditions. Treatment may involve lifestyle adjustments and medication.

1. Roseola infantum: This is a contagious viral infection commonly seen in infants, often accompanied by high fever, rash, and malaise. The course of the illness is relatively short and usually resolves spontaneously within a few days.

2. Acute gastroenteritis: This inflammation of the gastrointestinal tract is caused by viral or bacterial infections. Infants may experience symptoms such as fever, diarrhea, vomiting, and loss of appetite. Medications like bismuth potassium citrate tablets or enteritis relief granules may be used under medical guidance.

3. Upper respiratory tract infection: The aforementioned condition may result from an upper respiratory tract infection. Medications such as cefixime granules or amoxicillin granules may be administered under a doctor's supervision.

4. Otitis media: This ear infection, caused by bacteria or viruses, can lead to fever and ear pain in infants. It is often accompanied by additional symptoms such as pus discharge from the ear and hearing loss. Medications like clindamycin hydrochloride tablets or azithromycin capsules may be used under medical guidance to relieve discomfort.

5. Pneumonia: This lung infection is caused by bacteria, viruses, or other microorganisms. Infants may present with fever, cough, rapid breathing, and poor appetite. Treatment may include medications such as ambroxol hydrochloride tablets or ribavirin granules, as directed by a physician. Additionally, ensure the infant avoids areas with poor air quality.

If symptoms persist or worsen, seek immediate medical attention to prevent the condition from deteriorating.

Can I use white liquor to wipe a child with a high fever of 40 °C?
It is generally not recommended to use white liquor (baijiu) to sponge down a child with a high fever of 40°C, as it may cause physical discomfort. If white liquor is used to wipe the skin, the alcohol it contains has relatively strong absorption and penetration capabilities, which may lead to alcohol poisoning. For a child with a high fever of 40°C, antipyretic medications may be used under a doctor's guidance. Commonly used medications include ibuprofen suspension and acetaminophen tablets.
