Herpes pharyngitis is caused by coxsackievirus type A. It occurs in summer and fall. It occurs in children and is mainly transmitted by fecal-oral or respiratory route. Clinical manifestations: Fever, sore throat, small mucosal herpes and superficial ulcers in the isthmus are the main manifestations. It is a self-limiting disease with a general duration of 4-6 days, or up to 2 weeks in severe cases. The disease appears as a scattered gray-white herpes, 2-4 mm in diameter, with a red halo around the edge of the uvula, tonsils and soft palate, and gradually breaks down into ulcers. Transmission: Fecal-oral transmission, i.e., the virus is discharged through the stool and contaminates the environment, and then enters the respiratory or digestive tract to infect people. Gastrointestinal and respiratory transmission, i.e. infection by droplet transmission from patients with herpes pharyngitis or occult patients, or by eating contaminated unclean food. Transmission from person to person by direct or indirect contact with food, clothing, and utensils contaminated with the virus. Predisposing factors: Children with malnutrition, lack of exercise, allergies or immune deficiencies, low immune function, reduced body defenses are prone to infection and more severe symptoms, and are more likely to cause epidemics in the winter and spring seasons when the climate changes more. Environmental factors, such as atmospheric pollution, crowded housing, indirect smoke inhalation, passive smoking, etc., can reduce the local defenses of the respiratory tract and promote the growth and reproduction of pathogens. The chances of infection increase when children have opportunistic contact with patients with herpes pharyngitis or occult patients, share objects with other affected children, and come into close contact with the source of infection. Treatment: General treatment: rest, ventilation, and drinking plenty of water. Anti-infective treatment: antiviral drugs, Chinese medicinal preparations, and antibiotics only when combined with bacterial infection. Symptomatic treatment: antipyretic drugs: ibuprofen, acetaminophen in case of high fever, physical cooling in case of low fever; anti-stunning treatment in case of combined febrile convulsions.
