Herpetic pharyngitis is an acute upper respiratory tract infection caused by herpes simplex virus, mainly manifested as sore throat, fever, cough, sputum and other symptoms. In severe cases, complications such as difficulty breathing may occur.
1、 Symptoms and diagnosis of pediatric herpetic pharyngitis
(1) Causes and transmission routes
Herpetic pharyngitis is a viral disease caused by herpes simplex virus (HSV) infection. HSV is divided into two types: HSV-1 and HSV-2. HSV-1 often causes infections in the lips and throat, while HSV-2 often causes genital infections.
The virus can be transmitted through direct contact, such as coughing, sneezing, kissing, etc., as well as through indirect contact, such as sharing utensils, towels, toys, etc. In addition, herpetic pharyngitis may also be transmitted from mother to newborn.
（2） Symptom characteristics and clinical manifestations
The clinical manifestations of pediatric herpetic pharyngitis are diverse, and common symptoms include:
1. Throat pain and burning sensation, often accompanied by symptoms such as cough, expectoration, hoarseness, etc;
2. Systemic symptoms such as fever, headache, fatigue, and muscle soreness;
3. Symptoms such as herpes, ulcers, and erythema may appear in the oral cavity, and lesions can be seen in the tongue, oral mucosa, and other areas;
4. Swelling of the throat, congestion of the posterior pharyngeal wall, obvious inflammation of the throat, and symptoms such as coughing and difficulty breathing may occur;
5. Some children may also experience symptoms such as swollen lymph nodes.
The symptoms of pediatric herpetic pharyngitis mostly appear within 2-7 days after infection, and usually gradually improve within 2-3 weeks. Severe cases of herpetic pharyngitis may cause respiratory complications such as tracheitis, bronchitis, etc. For babies with suspected symptoms, they should seek medical attention as soon as possible.
（3） Diagnostic methods and criteria
1. Diagnostic methods for pediatric herpetic pharyngitis:
1.1 Clinical manifestations: Determine whether it is herpetic pharyngitis based on medical history and clinical symptoms.
1.2 Virus isolation and PCR detection: Samples such as throat swabs can be collected for virus isolation and PCR detection to confirm the diagnosis.
1.3 Serological testing: Herpetic pharyngitis can be diagnosed by detecting HSV specific antibodies in the baby's serum.
It should be noted that the diagnosis of pediatric herpetic pharyngitis should take into account the baby's medical history, clinical symptoms, and laboratory test results to make a comprehensive diagnosis.
2. The diagnostic criteria for pediatric herpetic pharyngitis are as follows:
2.1 The baby has symptoms such as sore throat, fever, and cough, as well as lesions such as oral herpes;
2.2 The clinical manifestations of the baby are consistent with the characteristics of herpetic pharyngitis;
2.3 After clinical examination and laboratory testing, it was determined to be herpes simplex virus infection.
2、 Treatment plan for pediatric herpetic pharyngitis
(1) General treatment measures
The general treatment measures for pediatric herpetic pharyngitis include:
1. Rest: The baby needs to maintain sufficient rest to help the body recover.
2. Diet: One should consume light and easily digestible foods, avoiding spicy, stimulating, and excessively cold or hot foods.
3. Symptom relief: Measures such as oral cleaning and rinsing with salt water can be used to alleviate symptoms such as oral pain and burning sensation.
4. Control body temperature: Babies with fever can use physical cooling, antipyretic drugs, and other methods to control body temperature.
5. Maintain hydration: Ensure sufficient water intake and avoid dehydration.
The above treatment measures can help babies relieve pain, control symptoms, alleviate the condition, and accelerate physical recovery. Meanwhile, during the treatment period, the baby should not go to school or public places to avoid infecting others. If the symptoms are severe or persist for a long time, it is recommended to seek medical attention promptly.
（2） Antiviral therapy drugs
The main treatment drugs for pediatric herpetic pharyngitis are antiviral drugs, and commonly used antiviral drugs include:
1. Acyclovir: a broad-spectrum antiviral drug that can be used to treat herpes simplex virus infection. The common administration methods are oral or intravenous injection.
2. Valacylovir: It is an oral antiviral drug with high bioavailability that can be used to treat herpes simplex virus infection.
3. Famciclovir: It is also an oral antiviral drug that can be used to treat herpes simplex virus infection.
These drugs mainly inhibit virus replication, alleviate symptoms, and promote recovery. However, it should be noted that these medications should be used under the guidance of a doctor, and attention should be paid to the dosage, duration, and possible adverse reactions of the medication. At the same time, the treatment of pediatric herpetic pharyngitis also needs to be combined with the specific situation of the baby, and other treatment measures should be comprehensively considered to help the baby recover their health as soon as possible.
（3） Medications for relieving symptoms
In addition to antiviral drugs, there are also some medications that can help alleviate symptoms of pediatric herpetic pharyngitis, including:
1. Pain relievers such as acetaminophen, ibuprofen, etc., which can relieve symptoms such as oral pain and sore throat.
2. Oral cleaning solution: such as salt water, mouthwash, etc., can alleviate symptoms such as burning sensation and oral ulcers.
3. Anti inflammatory drugs such as loratadine and chlorpheniramine can alleviate symptoms such as sore throat and tonsillitis.
4. Moisturizing agents: such as glycerin, throat lozenges, etc., can alleviate symptoms of dryness and throat irritation.
（4） Management of complications of pediatric herpetic pharyngitis
1. Throat edema: Throat edema is a serious complication that can lead to difficulty breathing. If symptoms such as shortness of breath, difficulty breathing, and hoarseness occur, seek medical attention immediately.
2. Secondary infection: Due to the virus damaging the mucosal barrier in the throat, bacteria are prone to infection, which can easily lead to secondary infections. If symptoms such as high fever, cough, and worsening throat pain occur, seek medical attention promptly.
3. Other complications: such as dehydration, malnutrition, neurological complications, etc.
The management of complications of pediatric herpetic pharyngitis requires treatment based on the specific condition of the baby, such as administering intravenous fluids, hydration, antibiotic therapy, etc. For serious complications such as laryngeal edema, immediate medical attention is required and corresponding treatment should be carried out under the guidance of a doctor.
3、 Prevention and precautions for pediatric herpetic pharyngitis
(1) Strengthen personal hygiene habits: wash hands frequently, change laundry frequently, do not share utensils with babies, etc.
（2） Pay attention to oral hygiene: Keep your mouth clean, brush your teeth in the morning and evening, rinse your mouth after meals, and avoid oral bacterial infections.
（3） Avoid contact with baby's secretions such as saliva, mucus, tears, etc.
（4） Avoid stimulating foods such as spicy and acidic foods, which can easily irritate the throat mucosa and worsen symptoms.
（5） Enhance physical fitness: Pay attention to dietary nutrition, avoid picky eating, and maintain good lifestyle habits.
Pediatric herpetic pharyngitis is a common infectious disease, mainly characterized by symptoms such as throat pain, fever, dry throat, cough, etc., which are easily misdiagnosed as other diseases. We should raise awareness of pediatric herpetic pharyngitis, strengthen prevention and control measures to reduce the occurrence and spread of the disease, and also enhance our own health awareness and lifestyle habits to maintain good physical condition.
