Summer is fast approaching and there is a significant increase in the number of children with herpes pharyngitis in the outpatient clinic. If a baby has a sudden high fever without symptoms such as cough, runny nose, or diarrhea, parents should check the baby’s mouth and throat for herpes or even ulcers, and pay attention to areas such as the palms of the hands and feet. Pediatric herpes pharyngitis is caused by the coxsackie group A virus and is prevalent in the summer and fall. The disease is epidemic and is commonly seen in children under 5 years of age. Clinical features include sudden onset of high fever with sore throat, headache, anorexia, and often pain in the neck, abdomen, and extremities. In infants, vomiting and convulsions often occur. Within 2 days of onset, a few (rarely more than 12) small (1-2 mm in diameter) grayish-white herpes appear on the oral mucosa, surrounded by a red halo, mostly on the anterior tonsils, but also on the soft palate, tonsils, uvula, tongue, etc. Within the next 24 hours, the blisters break down into shallow ulcers, usually less than 5 mm in diameter, which heal within 1-5 days. Complications are rare: symptoms usually disappear within 7 days. Durable immunity develops after infection, but other types of viruses in group A or other enteroviruses may also cause reoccurrence. If the disease occurs alone, there are often no systemic symptoms. Children present with a rapid onset, sudden onset of high fever, early onset of runny nose, followed by complaints of oral pain or refusal to eat in older children, and irritability, crying, drooling, yellow, short urine, and dry, balled-up stools in younger babies. On examination, small grayish-white herpes can be seen on the palate, oral mucosa, posterior pharyngeal wall, tonsils, and other oral mucosa of the child, and the herpes breaks down to form an ulcer in about 1-2 days. Herpes pharyngitis is usually associated with bleeding gums when touched, a foul odor in the mouth, and swollen submandibular lymph nodes, but rarely affects the skin outside the mouth.
