What should I do if a child has a high fever, does not sweat, and the fever does not subside?

Generally speaking, high fever refers to high body temperature, and fever reduction refers to lowering the temperature. If a child experiences persistent high fever without sweating or temperature reduction, it may be related to factors such as chilling, infantile emergency rash, urethritis, systemic lupus erythematosus, leukemia, and others. It is recommended to treat according to the underlying cause promptly, such as general treatment or medication. If symptoms cannot be relieved, timely medical attention is necessary. Detailed analysis is as follows:

1. Chilling

During chilling, viral or bacterial invasion into the body may cause persistent high fever and even lack of sweating. It may also be accompanied by symptoms such as sneezing and a runny nose. It is recommended to use medications such as oseltamivir phosphate granules, cefixime dry suspension, and ibuprofen suspension drops under a doctor's guidance. The child should also avoid cold environments to prevent worsening of the condition.

2. Infantile Emergency Rash

Infantile emergency rash is usually associated with human herpesvirus 6 infection. During the initial stage of the disease, the virus may cause fever and lack of sweating, often accompanied by red maculopapular rashes and itching on the skin. Treatment should follow a doctor's advice to use medications such as acyclovir for injection, infantile Chai Gui antipyretic granules, and paracetamol oral solution. Wiping the skin with warm water can help maintain dryness and cleanliness.

3. Urethritis

Urethritis is associated with bacterial infection of the urethra. Repeated bacterial irritation of the urethra may cause the above discomfort, usually accompanied by frequent urination, urgency, and pain during urination. Treatment may involve medications such as amoxicillin-clavulanate potassium granules, cefaclor granules, and ibuprofen suspension, under a doctor's guidance. Warm water cleansing after each urination can help eliminate bacteria.

4. Systemic Lupus Erythematosus

Systemic lupus erythematosus is usually associated with abnormal immune function. When the immune system attacks the body itself, it may cause persistent high fever, preventing the body from sweating normally. It is often accompanied by joint pain and swelling. Prompt treatment under a doctor's guidance is necessary, using medications such as prednisolone acetate injection, methylprednisolone sodium succinate for injection, and Qingkailing granules.

5. Leukemia

Leukemia is a blood disorder usually associated with abnormal immune function and blood-forming function. As the condition worsens, the above symptoms may appear, often accompanied by anemia and bleeding. Treatment should strictly follow medical advice using medications such as ifosfamide for injection, dexamethasone sodium phosphate injection, and paclitaxel injection.

There are many possible reasons for persistent fever in children. It is recommended to first identify the underlying cause before initiating treatment. Avoid self-medicating before the cause is confirmed. Additionally, during treatment, the child's emotions should be comforted to prevent emotional disturbances from affecting disease management.
