Why Does My Baby Always Have a Fever in the Afternoon?

Fever generally refers to a rise in body temperature. If a baby has recurrent fevers in the afternoon, it is often related to incomplete neurological development. Other possible causes include infantile rash, influenza, pneumonia, and other reasons. It is recommended to identify the cause and treat it accordingly.

Causes and Treatments:

1. Incomplete neurological development: If the baby is relatively young, it may have incomplete development of the neural regulation center. This can be influenced by external heat sources, potentially triggering the fever. If there are no accompanying symptoms of discomfort, special treatment is not required. It is recommended to drink plenty of warm water to promote metabolism.

2. Infantile rash: This is often caused by infection with human herpesvirus type 6. It can lead to a fever that may reach 39℃-40℃ and typically lasts for 3 to 5 days. After the fever resolves, a rash may appear. Parents can follow the doctor's advice and administer medications such as acetaminophen oral suspension, ibuprofen granules, and acyclovir granules to reduce the fever and antiviral effects.

3. Influenza: This is an acute respiratory infection caused by the influenza virus. It is characterized by high fever, fatigue, sore throat, and other symptoms. The fever often occurs at night or in the evening. The doctor may prescribe medications such as oseltamivir phosphate granules, antiviral oral liquid, and isatis granules for antiviral treatment.

4. Pneumonia: If the baby's lungs are infected by bacteria or viruses, it can lead to a lung infection. This may manifest as cough, sputum production, and irregular fever. The doctor may prescribe antibiotics such as amoxicillin granules, cefaclor granules, and cephalexin granules to treat the infection and reduce inflammation.

Other possible causes include tuberculosis, which may manifest as hemoptysis, night sweats, and other symptoms. In such cases, the doctor may prescribe medications such as ethambutol hydrochloride tablets, rifampicin tablets, and isoniazid tablets for antituberculous treatment. If the condition is severe, it is recommended to seek medical attention at a formal hospital.
