The whole prescription has the functions of anti-inflammation, anti-virus, clearing away heat, detoxicating and relieving sore throat, which accords with the principle of syndrome differentiation and treatment of exogenous wind-heat syndrome in traditional Chinese medicine.

Seasonal influenza has a strong interpersonal transmission ability, and active prevention and control is more important than limited effective treatment measures. The main preventive measures are as follows.

Strengthen the publicity and education of personal hygiene knowledge

1. Keep indoor air circulation and avoid going to crowded places in peak season.

2. Use paper towels when coughing or sneezing to avoid the spread of droplets.

3. Wash your hands often and thoroughly to avoid dirty hands touching your mouth, eyes and nose.

4. If flu-like symptoms appear during the epidemic, seek medical advice in time, reduce contact with others and try to rest at home.

5. Influenza patients should be isolated from respiratory tract 1 week or until the main symptoms disappear. The patient's utensils and secretions should be thoroughly disinfected.

6. Strengthen outdoor physical exercise to improve the body's disease resistance.

7. The climate in autumn and winter is changeable, so pay attention to adding and subtracting clothes.

8. Prevention and control of institutional outbreaks: When influenza has been prevalent in the community, if two or more people in the same institution have flu-like symptoms within 72 hours, they should be vigilant and actively carry out pathogen detection. Once diagnosed, patients should be required to stay in hospital or rest at home, do a good job of personal hygiene and try to avoid and reduce contact with others. When it is confirmed as an epidemic in an institution, it shall be implemented in accordance with the relevant provisions of the Law on the Prevention and Control of Infectious Diseases and the Regulations on Public Health Emergencies. When nosocomial infection occurs, measures such as isolation and protection should be implemented according to the provisions of relevant technical guidelines.

9. Vaccination against influenza: Vaccination against influenza is the most effective means to prevent influenza and its complications, which is irreplaceable by other methods. Vaccines need to be vaccinated every year to be effectively protected, and the replacement of vaccine strains is decided by WHO according to the global monitoring results. Priority vaccination population:

(1) High-risk group of post-influenza complications ①6-59 months infants. ② Older people over 60 years old. ③ Adults and children with chronic respiratory diseases, cardiovascular diseases, nephropathy, liver diseases, hematological diseases and metabolic diseases. ④ Adults and children with immunosuppressive diseases or low immune function. ⑤ People who can't take care of themselves and people who are at risk of aspiration such as upper respiratory secretions due to difficulty in self-expectoration caused by nervous system diseases. ⑥ Long-term residence in nursing institutions for chronic diseases such as sanatoriums. ⑦ Pregnant women and women who plan to get pregnant during the flu season. ⑧65438+ Teenagers under the age of 08 who have been treated with aspirin for a long time.

(2) People who have a greater chance to spread influenza virus to high-risk groups ① Medical and health workers. (2) nursing homes, nursing homes and other chronic disease care institutions staff. ③ Family members and caregivers of people at high risk of post-influenza complications.

(3) Contraindications ① Those who are allergic to egg protein or any vaccine. ② Patients with moderate and severe acute fever. ③ Patients with Guillain-Barre syndrome. The doctor thinks that others can't get the flu vaccine.

(4) Vaccination method and opportunity ① Children aged 6 months to 9 years who have never been vaccinated with influenza vaccine or only received 1 dose in the previous year should be vaccinated twice, with an interval of 4 weeks; Inoculate 1 dose before influenza season every year in the future. Others take 1 dose every year. ② Inoculation route is intramuscular injection or subcutaneous deep injection, and it is recommended that infants choose intramuscular injection of lateral thigh. ③ Vaccination should be started in most areas of China before 10 every year.

10. antiviral drug prevention: drug prevention can not replace vaccination, but can only be used as an emergency temporary preventive measure for high-risk groups with complications who have not been vaccinated or have not gained immunity after vaccination. Antiviral drugs sensitive to epidemic strains should be selected as preventive drugs, and the course of treatment is determined by doctors, usually 1 ~ 2 weeks. It is estimated that it is difficult to obtain effective immune effect for people who have been vaccinated but are immunosuppressed for various reasons. Whether to add antiviral drugs for prevention and the timing, course of treatment and dosage of administration should also be judged by doctors.

(1) TCM prevention: those who have definite contact with influenza patients: ① Children, young adults and people in good health can take the following: honeysuckle, isatis indigotica leaves, mint and raw licorice in water, daily 1 dose, for 5 days. ② For the elderly and infirm, Radix Codonopsis, Folium Perillae and Herba Schizonepetae can be decocted in water, daily 1 dose for 5 days.

(2) Dietary attention: After suffering from the flu, you should eat a light diet and eat more foods that are digestible and rich in vitamins. At the same time, pay attention to drink plenty of water, mainly boiled water. Do not eat salty food: after eating salty food, it is easy to contract the mucosa of the affected area and aggravate nasal congestion. Symptoms such as throat discomfort. Moreover, salty food is easy to produce phlegm and stimulate local cough. Fasting sweet and greasy food: sweet food can help wet, but greasy food is not easy to digest, so patients with cold should avoid all kinds of candy, drinks, fat and so on. Fasting spicy food: spicy food is easy to burn body fluid, which helps fire to produce phlegm, making it difficult to cough up phlegm, so people with colds should not eat it, especially onions. It is not suitable to eat barbecue and fried foods: the smell of such foods stimulates the respiratory tract and digestive tract, which easily leads to mucosal contraction, aggravates the condition and is not easy to digest. At the same time, you should also avoid alcohol and tobacco.
