Herpes in the throat of a child is generally considered to be a symptom of herpes pharyngitis, which can occur when the body resistance of a child is reduced and an intestinal virus infection causes herpes pharyngitis. Parents should promptly take their children to the hospital for treatment to avoid delaying the condition. The main clinical manifestations are fever, sore throat, drooling, anorexia, vomiting, etc. On physical examination, the child may have a congested pharynx and several 2-4 mm grayish-white herpes surrounded by a red halo on the mucosa of the soft palate, pharyngopalatine arch and uvula. 1-2 weeks later these herpes may break down to form small ulcers. Parents can apply lidocaine to the child’s mouth under medical supervision, or use an open-throat sword spray, or gargle with Rehab to help promote healing of the herpes. If the child is accompanied by fever, he may take ibuprofen suspension or ibuprofen capsules to reduce fever under doctor’s supervision, and he may also take oral anti-inflammatory oral solution of busulfan or ribavirin granules for antiviral treatment. If bacterial infection is present, oral cefixime or amoxicillin is required for anti-inflammatory treatment. Children should pay attention to a light diet during the treatment period and try to eat an easy-to-digest liquid diet, such as rice soup and vegetable soup, to avoid increasing the sore throat. Parents should pay attention to supervise and help their children to clean their mouths well, and rinse their mouths with highly concentrated saline, which can kill the bacteria in the mouth.
