When herpes pharyngitis occurs, most children's blood does not rise or fall in white blood cells (white blood cells often rise during bacterial infection, and white blood cells are normal or reduced by viral infection). The clinical symptoms of herpetic pharyngitis include fever, sore throat, and small herpes on the mouth, soft palate, and tonsils, uvula. The early stage of herpes is a grayish white papule, which is surrounded by redness and becomes a shiny herpes. It becomes a small ulcer after rupture.

Herpes pharyngitis
Examination of oropharyngeal and nasopharyngeal mucosa diffuse hyperemia, swelling, sacral arch and uvula edema, posterior pharyngeal lymphoid follicles and pharyngeal lateral cord redness; yellow-white spotted exudate on the surface, mandibular lymph nodes and tenderness . The body temperature can be increased to 38 ° C, depending on the pathogen, white blood cells can be increased, normal or reduced.
Diagnosis
Diagnosis and diagnosis of herpetic pharyngitis
diagnosis
Diagnosis can be made based on symptoms and characteristic oral damage. It is best to confirm by isolation of the virus from the lesion or by an increase in characteristic antibody titers, but these tests are not recommended for routine use.
Differential diagnosis
1, herpetic stomatitis, which is characterized by any season can occur, showing a larger, longer lasting ulcer.
2, recurrent aphthous and Bednar (Bednar) mouth sores rarely occur in the pharynx, and generally no systemic symptoms.
3, Coxsackie A group 10 virus can also cause similar lesions (lymph node pharyngitis), but the oropharynx lesions are prominent, showing a white to yellow nodules, treatment for symptomatic treatment.
