The concept of "prevention before disease, prevention of change after disease, and prevention after relapse" is a powerful weapon for traditional Chinese medicine to deal with major epidemic situations. Recently, in the process of combating the epidemic of COVID-19, many places have adhered to the combination of traditional Chinese and Western medicine and the use of both Chinese and Western medicine. Traditional Chinese medicine has been involved in the whole process and deeply participated in the prevention, control and treatment, playing a unique advantage and important role in all stages of "prevention, treatment and health". Prevention before disease and early intervention with traditional Chinese medicine can build a "traditional Chinese medicine epidemic prevention barrier" as soon as possible. Mou shanyong, deputy director of Shandong Provincial Health Commission, introduced that in this round of epidemic, Shandong province implemented traditional Chinese medicine intervention methods for key groups such as centralized isolation personnel to ensure that the isolation points "point to prescribe medicine"; Prescriptions are used for key groups such as close contact, isolation and staff in the province. As of May 12, a total of 2.831 million Chinese medicine intervention prescriptions and 293000 Chinese patent medicines had been distributed to 1703 isolation points in the province, effectively reducing the incidence rate. Traditional Chinese medicine intervention is also one of the ten key actions for epidemic prevention and control in Shanghai. In the early stage of this round of epidemic, the Shanghai Municipal Health Commission and the Shanghai Municipal Administration of traditional Chinese medicine took traditional Chinese medicine intervention on people in isolation points and key sealed areas. Zhang Wei, a member of the medical treatment expert group of COVID-19 in Shanghai, introduced that in view of the core symptoms of the current round of epidemic in Shanghai, the expert group has formulated a prescription for epidemic prevention instead of tea, and has also formulated a "Fuzheng anti epidemic prescription" in conjunction with the national epidemic prevention and control base of traditional Chinese medicine, which is suitable for strengthening intervention in high-risk and key populations. Light does not turn to heavy, heavy does not turn to dangerous. The guiding ideology of "prevention and change of existing diseases" of traditional Chinese medicine helps to concentrate more efforts to rescue critically ill patients. The anti epidemic practice over the past two years also shows that giving full play to the unique advantages of traditional Chinese medicine, adhering to the combination of traditional Chinese and Western medicine and the combination of traditional Chinese and Western medicine can effectively reduce the weight conversion rate and disease death rate. Mou shanyong introduced that in this round of epidemic, Shandong Province optimized the TCM diagnosis and treatment plan, standardized TCM diagnosis and treatment through measures such as itinerant guidance and remote consultation of Provincial TCM experts, sending experts to designated hospitals to guide TCM treatment, confirmed cases "one person, one party", "daily TCM ward round" and equipped with tube bed TCM doctors, and formed a "1 + 1gt; 2" treatment joint force with complementary advantages of traditional Chinese and Western medicine. In the treatment of patients with high-risk factors and severe patients, more attention should be paid to the early intervention of traditional Chinese medicine and the early application of integrated traditional Chinese and Western medicine. At the press conference on the prevention and control of the novel coronavirus pneumonia epidemic in Beijing on May 7, Li angzeng, deputy director of the Beijing Municipal Commission of health, introduced that since April 22, there have been more elderly patients or patients with a variety of basic diseases in the local cases related to the current round of epidemic in Beijing. In this regard, Beijing adheres to the daily multidisciplinary expert consultation mechanism in the treatment of patients, including infection, severe illness, respiration, traditional Chinese medicine, imaging, testing and other disciplines to evaluate patients; Pay attention to early treatment and treatment of basic diseases, pay equal attention to traditional Chinese and Western medicine, actively explore and use relatively mature new drugs and new treatment methods, strengthen basic nursing and care, and improve the effect of medical treatment. The latest information shows that as of 15:00 on May 17, Beijing Ditan hospital and Xiaotangshan fangcang hospital had treated more than 1100 patients with COVID-19, and 541 patients had been cured and discharged or released from isolation. In the hospital, except for one patient with multiple basic diseases, the rest were in stable condition and had no dangerous severe cases. Shanghai also attaches importance to the coordinated treatment of critically ill patients with Chinese and Western medicine, and carries out syndrome differentiation and treatment for critically ill and critically ill patients according to the principle of "one person, one policy". Zhaodandan, deputy director of the Shanghai Municipal Commission of health, introduced that Shanghai has formulated an expert consensus on optimizing the TCM treatment of elderly patients with novel coronavirus infection, strengthened the allocation of TCM first aid drugs for severe and critical diseases in designated hospitals, and established a municipal multidisciplinary TCM expert group composed of national famous TCM doctors, Shanghai famous TCM doctors and Qihuang scholars with experience in the treatment of infectious diseases, Zhang Boli, academician of the Chinese Academy of engineering, and other experts of the national working group were invited to hold consultations and discussions on critical cases in municipal and district designated hospitals every day, and carry out joint ward rounds of traditional Chinese and Western medicine. For patients with COVID-19, rehabilitation is as important as treatment. The implementation of the whole process of traditional Chinese medicine rehabilitation can promote the functional recovery of patients and effectively reduce the psychological pressure of medical workers and the public. According to reports, in view of the respiratory tract infection and psychological fear and anxiety of the diagnosed patients, as well as some negative patients who still have symptoms such as fatigue and Qi deficiency after discharge, Shandong Province has accelerated the recovery of patients' functions through special traditional Chinese medicine preparations, physical and mental adjustment programs and non drug therapy, and provided psychological counseling and traditional Chinese medicine health guidance to the public through the entry of traditional Chinese medicine doctors and the "12355" service hotline; Shanghai printed and distributed the TCM rehabilitation program during the convalescent period of novel coronavirus infection, providing guidance and reference for patients' home-based rehabilitation and medical institutions to provide rehabilitation services.
