Acute purulent pharyngitis in children may be a recurrent fever, mostly due to the lack of proper treatment or the development of comorbidities. 1. Failure to treat correctly: When a child suffers from acute suppurative pharyngitis, it is usually necessary to choose the appropriate treatment according to the pathogen of the infection. If the correct treatment is not carried out, recurrent fever may occur. 2. The emergence of comorbidities: acute suppurative pharyngitis is an acute inflammation that occurs in the throat area, and if the inflammation is heavily infected, it may spread to other tissues, such as causing acute suppurative tonsillitis, acute laryngitis and so on. Once these comorbidities are caused, recurrent fever may occur in your child. If your child’s acute suppurative pharyngitis is always recurring fever, it is recommended to consult a doctor in time, under the guidance of the doctor, improve the relevant examination, clarify the cause of the disease, and symptomatic treatment.
