疱疹性咽峡炎怎么引起的

Generally, herpangina may be caused by environmental factors, poor personal hygiene, weakened immunity, contact transmission, or enteroviral infection. If symptoms of herpangina occur, it is recommended to seek timely medical attention at a hospital to avoid delaying treatment. The specific analysis is as follows:

1. Environmental Factors

Climate changes, air pollution, and smoke can all affect the body's immune system, thereby increasing the risk of illness. It is recommended to rest in bed during fever, and light activities may be resumed after the fever subsides. Ensure proper indoor ventilation.

2. Poor Personal Hygiene

Infrequent handwashing and neglecting oral hygiene increase the risk of viral infection. It is advised to brush teeth after breakfast and before bedtime to maintain oral cleanliness, and to wash hands frequently.

3. Weakened Immunity

Insufficient immune resistance may lead to the development of herpangina. A weakened respiratory barrier function results in reduced secretion of immune substances and decreased ability to fight pathogens, thus increasing susceptibility to the disease. Patients can improve their immunity through proper diet and regular exercise.

4. Contact Transmission

Herpangina can spread via respiratory droplets, direct contact, or sharing daily necessities. In such cases, patients may experience symptoms such as fever and cough. Medications such as Pudilan Xiaoyan Tablets, Lanqin Oral Liquid, and Paracetamol Tablets may be used under medical guidance.

5. Enteroviral Infection

Enteroviral infections may cause herpangina. These viruses include Coxsackievirus A and Enterovirus 71. Symptoms following infection may include fever and sore throat. Treatment may include Ribavirin Dispersible Tablets, Ganciclovir Capsules, or Acyclovir Tablets, used as directed by a physician.

Patients are advised to rest at home in isolation, as herpangina is contagious. Going out during the illness may lead to spreading the infection to others.
