The child has herpetic pharyngitis

If a child develops herpetic pharyngitis, it will be difficult to cure. This is a common upper respiratory tract infection. Once this happens, it will seriously affect the patient's health and must be treated in time. In addition, the incidence of this disease will become higher in the autumn and winter seasons, so it is necessary to prevent your children from viral infections.

It is often part of an upper respiratory tract infection but can also occur alone. It often occurs in autumn and winter and between winter and spring.

1. Viral infection

Coxsackievirus, adenovirus, and parainfluenza virus are the most common, and are mostly transmitted through droplets and close contact.

2. Bacterial infection

The main bacteria are streptococci, staphylococci and pneumococci, as well as fusobacteria and others. If bacteria or toxins enter the blood, purulent lesions may even occur in distant organs.

3. Other pathogens

Spirochete, etc.

4. Causes

Many pathogens are conditional pathogens, which usually coexist in the oral cavity of healthy people without causing disease. However, when the body's resistance is reduced, such as due to excessive fatigue, malnutrition, excessive stress, depression, poor environmental hygiene, vitamin deficiency, gastrointestinal diseases, unclean mouth, caries, cachexia, blood disease, poisoning, etc., this disease can be induced. It can also be transmitted through sharing eating utensils. [1]

Pharyngitis is an acute inflammation that occurs in the pharyngeal isthmus and is a special type of pharyngitis. The pharyngeal isthmus refers to a ring-shaped structure on the vertical plane of the pharynx. The upper part is the uvula and the free edge of the soft palate on both sides, the lower part is the root of the tongue, and the left and right sides are the palatoglossal arch and palatopharyngeal arch. These four structures together form a narrow annular part called the pharyngeal isthmus. Pharyngitis can be caused by bacteria, viruses and other pathogens, and manifests as sore throat, dry throat, foreign body sensation, herpes, ulcers, etc., which are similar to the symptoms of acute tonsillitis.

There are several specific types of pharyngitis. ① Herpetic pharyngitis in children is mainly caused by infection with enterovirus Coxsackie group A virus. Characterized by acute onset of fever and sore throat, red halos on the mucosa and characteristic surrounding vesicular rash; ② Vincang pharyngitis, also known as ulcerative pharyngitis or ulcerative tonsillitis, is a subacute tonsillitis caused by infection with Fusobacterium and Vincang Borrelia, characterized by obvious localized inflammatory reaction and ulcer formation.
