What are the common causes of frequent fevers in children?

Generally, the main causes of frequent fevers in children include incomplete immune function, improper care, pediatric tonsillitis, urinary tract infections in children, and congenital heart disease with infections. If discomfort symptoms occur, it is recommended to seek timely treatment at a regular hospital. Detailed analysis is as follows:

1. Incomplete Immune Function

A child's immune system is not yet fully developed, and the activity of immune cells is relatively low, making it difficult to effectively resist pathogen invasion, which can lead to repeated infections and fever. Daily care should ensure the child consumes sufficient protein and vitamins, such as eggs and oranges. The child should engage in about 30 minutes of outdoor activities like walking and playing each day to enhance immunity and reduce the chances of infection.

2. Improper Care

If parents do not adjust children's clothing according to temperature changes, or if children remain in damp clothes after sweating, it can easily lead to chill or overheating, causing recurrent fever. Close attention should be paid to weather changes, clothing should be added or removed promptly when there is a large temperature difference between morning and evening, and wet clothes should be replaced immediately after sweating to keep the body dry and reduce the risk of fever.

3. Pediatric Tonsillitis

The tonsils, as an immune barrier, are susceptible to inflammation from bacterial or viral infections. Repeated inflammation can cause frequent fevers in children, accompanied by sore throat and swollen tonsils. Under a doctor's guidance, medications such as children's Yanbian granules, Cefaclor dry suspension, and Ribavirin granules may be taken to combat infection and alleviate inflammation. If the tonsils repeatedly become inflamed and meet surgical criteria, a tonsillectomy may be considered.

4. Pediatric Urinary Tract Infection

Bacterial invasion into the urinary tract can cause infection, and the resulting inflammation may lead to frequent fevers in children, possibly accompanied by frequent and urgent urination. Under a doctor's guidance, medications such as Cefixime granules, Amoxicillin Clavulanate Potassium dry suspension, and Nitrofurantoin enteric-coated tablets can be taken to inhibit bacterial growth. Encourage the child to drink more warm water to increase urine output and promote the elimination of pathogens.

5. Congenital Heart Disease with Infection

Children with congenital heart disease have abnormal heart structures, which can obstruct blood circulation and weaken resistance, making them prone to repeated lung infections and frequent fevers. Immediate medical attention is necessary. Under a doctor's guidance, medications such as Ceftriaxone Sodium for injection, Penicillin Sodium for injection, and children's Pulmonary Heat Cough and Asthma Oral Liquid can be used to fight infection and relieve symptoms. Additionally, surgical treatments such as ventricular septal defect repair or atrial septal defect closure may be performed depending on the cardiac lesion.

In daily life, maintaining a clean home environment and regular disinfection is important. Children should be encouraged to wash their hands frequently and avoid rubbing their mouths and noses with dirty hands. Regular vaccinations should be ensured to prevent infectious diseases, and follow-up visits should be conducted as per medical advice to monitor the child's health status.
