The baby has had a fever for several days, and it keeps coming back. What should I do?

Fever generally refers to an elevated body temperature. When a baby has had a fever for several days with persistent recurrence, targeted treatment based on the underlying cause is recommended. Common causes include viral colds, infantile emergency rash (roseola), acute suppurative tonsillitis, chronic bronchitis, and pneumonia.

1. Viral Cold

A severe viral cold can lead to increased inflammatory mediators that repeatedly stimulate the body's temperature regulation center, making it easy for symptoms such as recurrent fever and coughing to occur. If axillary temperature does not exceed 38.5°C, physical cooling methods such as fever-reducing patches or lukewarm water sponge baths may be used. If axillary temperature exceeds 38.5°C, medications like acetaminophen sustained-release tablets, ibuprofen suspension, or ibuprofen sustained-release tablets may be administered under medical guidance.

2. Infantile Emergency Rash (Roseola)

This contagious disease is caused by infection with different types of human cytomegalovirus. Main symptoms include fever, rash, and sore throat. The fever tends to last for a prolonged period and often recurs as high fever. Drinking plenty of water, maintaining a light diet, and appropriately using antipyretic medications under a doctor’s guidance—such as ibuprofen suspension, ibuprofen granules, or acetaminophen granules—can help improve symptoms.

3. Acute Suppurative Tonsillitis

This respiratory tract disease results from bacterial infection, causing inflammation and swelling of the tonsils, significantly reducing immune function and affecting the temperature regulation center, leading to persistent fever. Other accompanying symptoms include sore throat and difficulty swallowing. According to medical advice, antibiotics such as cefaclor granules or cephalexin granules may be prescribed to reduce fever and improve the condition.

4. Chronic Bronchitis

In cases of chronic bronchitis, where inflammation has not been completely resolved and is repeatedly triggered by bacterial or viral infections, medications such as antiviral granules, amoxicillin capsules, or cefaclor granules may be used under medical supervision to eliminate inflammation and improve recurrent fever.

5. Pneumonia

For patients with pneumonia, incomplete recovery from lung infection may lead to recurrent fever. Under medical guidance, medications such as ribavirin granules, azithromycin tablets, or roxithromycin tablets can be used to reduce inflammation and relieve fever symptoms.

Children who frequently experience fever should promptly visit a hospital to determine the exact cause and follow doctors’ recommendations for appropriate treatment to prevent delays in managing the illness.
