There are many reasons for babies to have recurrent fever for several days in a row, commonly caused by factors such as influenza, pneumonia, juvenile idiopathic arthritis and so on.
1. Influenza: because the baby’s body is less resistant to disease, when infected by influenza A, influenza B virus, will lead to a large number of viruses in the respiratory mucosa, and spread to other cells, thus stimulating the central thermoregulatory system, resulting in a few days in a row of recurring fever symptoms.
2. Pneumonia: If the baby’s lungs are infected by bacteria, it will cause inflammation in the lungs, and if the condition is more serious, it will lead to the stimulation of the body’s immune system by inflammatory factors, which will lead to the symptom of recurrent fever for several days in a row.
3. Juvenile idiopathic arthritis: a common rheumatic disease in childhood, mainly characterized by chronic synovitis, accompanied by systemic damage to the function of multiple organs, each time the fever is often more than 2 weeks.
There may be other reasons for the baby’s repeated fever for several days in a row, so you should go to the hospital to improve the examination and cooperate with the doctor to give targeted treatment to minimize the adverse effects of the disease.
