What to do if a 4-year-old child has a fever of 39°C?

Generally speaking, fever refers to elevated body temperature. Fever in a 4-year-old child may be related to factors such as drug allergy, heatstroke, upper respiratory tract infection, infantile emergency rash, and pneumonia. Prompt treatment according to the underlying cause should be administered, such as general treatment or medication. If discomfort occurs, timely medical attention is recommended. Detailed analysis is as follows:

1. Drug Allergy

If the child has previously taken certain medications and developed an allergic reaction, this may cause elevated body temperature, even high fever. It may be accompanied by symptoms such as skin itching and redness. The medication dosage should be adjusted promptly according to the doctor's instructions, and if necessary, discontinued immediately.

2. Heatstroke

Remaining in a high-temperature environment for a prolonged period may lead to an imbalance in the body's ability to regulate body temperature, resulting in high fever. Symptoms such as dizziness, headache, and nausea may also occur. The child should be moved to a cool place as soon as possible, and medications such as Shidi Shui (ten-drop water), Huoxiang Zhengqi Granules, and Shure Ganmao Granules should be administered according to medical advice.

3. Upper Respiratory Tract Infection

Upper respiratory tract infections are mainly caused by pathogens such as influenza virus and streptococcus. These pathogens can repeatedly stimulate the child's body, leading to elevated temperature, often accompanied by symptoms such as coughing and runny nose. Prompt treatment under a doctor's guidance with medications such as antiviral granules, amoxicillin granules, and Xia'er Anfenhuangnamin granules is recommended.

4. Infantile Emergency Rash

Infantile emergency rash is usually associated with viral infection. During the acute phase of the illness, body temperature may rise and even continue to increase, causing high fever. It may also be accompanied by symptoms such as listlessness and fatigue. Timely treatment under a doctor's guidance with medications such as ibuprofen suspension drops, antiviral oral liquid, and cetirizine hydrochloride drops is recommended.

5. Pneumonia

Pneumonia is an inflammation of the lungs caused by bacterial, viral, or mycoplasma infection. As the condition worsens, it may lead to persistent high fever and symptoms such as coughing and sputum production. Treatment should follow the doctor's advice using medications such as cefixime granules, ribavirin granules, and paracetamol oral solution.

It is recommended to promptly identify the cause of the child's fever and follow the doctor's advice for standardized treatment to avoid delaying recovery. When reducing fever, it is also important to improve the living environment and avoid excessively low or high temperatures.
