Herpes pharyngitis is a disease caused by an enterovirus. It is characterized by an acute onset of fever and sore throat. Red halo spots surrounded by a characteristic blistering rash or white herpes pharyngitis are seen on the back of the soft palate, pharynx, and tonsils as a common summer disease in children. To prevent this disease, parents should pay attention to keeping their children’s personal and indoor hygiene and try not to take them to noisy public places. Papules (lymph nodes). Most are mild cases with a self-limiting type (1 to 2 weeks). It is most common in children aged 3 to 10 years old and occurs in summer and autumn. It can occur several times in the same patient caused by different types of virus. The incubation period is 3 to 10 days. It starts with sudden onset of high fever and reaches a peak in 24-48 hours, rising to 39-41℃, accompanied by headache, throat discomfort, myalgia, etc. Infants and children often have vomiting, refusal to eat, and even febrile convulsions; older children and adults often have severe sore throat, difficulty swallowing, myalgia of the limbs, anorexia and weakness. After 4 to 5 days, a small gray papule appears on the pharynx, which develops into blisters and ulcers within 24 h. The lesions are surrounded by a red halo of 1 to 5 mm as a characteristic feature. The lesions are often found on the anterior tonsillar column, the edge of the soft palate and the palatal lobe. The ulcers heal in 1 to 5 days, and the fever usually subsides and the symptoms disappear within 3 days. The prognosis for this disease is good. Acute lymphatic isthmus is a variant of herpetic isthmus caused by coxsackievirus type A10. It has the same damage as typical isthmus, but does not progress to blisters and ulcers, and only a grayish-white papule surrounded by a red halo formed by lymphocytic infiltration remains.
