What Causes Herpangina?

Herpangina in children is a relatively common condition. Generally, it refers to pharyngeal infection caused by viruses or bacteria. In the early stage of the disease, small grayish papules appear, surrounded by a red halo. As the disease progresses and worsens, these lesions rupture to form ulcers, accompanied by pain. So, what causes herpangina?

What Causes Herpangina?

Herpangina is an acute respiratory infectious disease primarily caused by Coxsackievirus or other enteroviruses. It mainly affects children under six years of age, though adults may also be affected. Typical symptoms include fever, sore throat, and characteristic pharyngeal vesicles. Initial management involves isolation of the patient to prevent cross-infection. Strict hygiene measures must be applied to all items used by the patient—including food utensils and consumables. If the patient’s temperature exceeds 38.5°C, physical cooling methods (e.g., tepid sponging) or antipyretic medications should be administered. Antipyretics should be spaced at least 4–6 hours apart and not overused. Local interferon nebulization therapy may also be considered.

Herpangina is caused by viral infection and is particularly common among children and infants. The most frequently implicated viruses are Coxsackievirus A group and, less commonly, herpesviruses. Contributing factors include hot weather and poor indoor air circulation, which facilitate rapid viral proliferation and subsequent entry into the respiratory tract, triggering disease onset. Clinically, patients typically present with fever and sore throat. On initial examination, grayish-white vesicles surrounded by an erythematous halo can be observed on the oral mucosa; these vesicles later rupture and evolve into ulcers. Antiviral therapy is indicated for symptomatic treatment. Antibiotics are generally unnecessary unless there is evidence of concurrent bacterial infection.

Patients are advised to maintain regular daily routines—avoiding late-night activities, alcohol consumption, and smoking—and to engage in regular outdoor exercise to strengthen their immune system. We hope this information proves helpful.
