Herpes in the pharynx of children is called herpetic pharyngitis and is usually divided into the latent phase, blistering phase, ulcerative phase, and recovery phase, with the ulcerative phase generally being the more serious period of the disease and occurring about 3-6 days after the latent phase. The duration and stage of the disease varies from child to child, and the time of severity of the disease may vary. Herpes pharyngitis in children is mainly caused by intestinal viral infections, and there is an incubation period of about 2-7 days after infection, with no obvious symptoms. The symptoms are generally more severe than in other periods. During this period, if the child has difficulty in eating, he or she can be given fluids, and the fever can be cooled physically, or fever-reducing drugs, such as ibuprofen and acetaminophen, can be taken under the guidance of the doctor. Application of interferon and ribavirin can be considered if necessary. Herpes pharyngitis is a contagious disease and the whole course of the disease lasts about 1-2 weeks. It is recommended that the affected child be isolated from others and the items used by the affected child should be disinfected to prevent cross infection. The disease has a certain degree of recurrence, and care should be taken to maintain personal hygiene after recovery from the disease to avoid re-infection.
