Viral pharyngitis, also known as herpes pharyngitis, is an acute infectious disease caused by viral infection and characterized by acute fever and herpes ulcers in the pharynx. The typical clinical presentation is a congested pharynx with several small grayish-white herpes surrounded by a red halo on the oral mucosa within 2 days of onset. 2-3 days later the red halo increases and expands and the herpes breaks down to form a yellow ulcer. Mostly seen on the soft palate, uvula, tonsils, but does not involve the gingiva and buccal mucosa. Swallowing may be affected by severe sore throat. In infants and young children, it is characterized by salivation, refusal to eat, and irritability. Some children also have acute fever, mostly low or moderate, occasionally up to 40℃ or more, even causing convulsions, and the fever duration is mostly 2-4 days. A few severe cases can also be complicated by mumps and myocarditis. The disease is mainly transmitted by fecal-oral or respiratory route and is highly contagious. Patients with herpes cheek infection and those with latent infection are the main sources of infection. The disease is self-limiting and generally lasts 4 to 6 days, with severe cases requiring antiviral medication. Herpes pharyngitis is easily mistaken for the common cold in its early stages. Once a child develops symptoms, parents should promptly take the child to the pediatric department of a regular hospital to avoid delaying the disease.
