At present, China's epidemic prevention and control has entered a new stage, and the focus of work has shifted from "preventing infection" to "protecting health and preventing severe diseases". Guo Yanhong, Director of the Medical Emergency Department of the National Health Commission, said at the recent press conference of the joint prevention and control mechanism of the State Council that COVID-19 infected people, especially the elderly, tend to combine some basic diseases, while COVID-19 infection will also aggravate basic diseases. Therefore, the tenth edition of novel coronavirus Infection Diagnosis and Treatment Plan strengthens the concept of co treatment of COVID-19 infection and basic diseases. It is not only necessary to strengthen the treatment of COVID-19 infection, but also to carry out cause and symptomatic treatment for basic diseases, and promote the comprehensive recovery of patients' health through multidisciplinary consultation. Guo Yanhong introduced that the diagnosis and treatment plan is a professional and technical standard to guide clinical medical personnel to diagnose and treat patients infected with COVID-19. According to the 10th edition of the diagnosis and treatment plan, according to the severity of the patients' condition, the patients can be divided into light, medium, heavy and critical, which is more in line with the clinical practice, and is conducive to the comprehensive study and judgment of the patients' condition by medical staff and the adoption of comprehensive treatment measures. "At present, the overall pathogenicity of the Omixon virus strain has declined after infection, but some elderly people with basic diseases, no vaccination, and low immune function will have severe diseases, such as severe pneumonia, respiratory failure, etc." Wang Guiqiang, director of the Infectious Diseases Department of the First Hospital of Peking University, said that the 10th edition of the diagnosis and treatment plan is clear, Severe cases of COVID-19 infection are defined as severe cases with pneumonia caused by COVID-19 infection as the main manifestation, and severe cases caused by other underlying diseases or other diseases are defined as severe cases caused by underlying diseases or other diseases. For severe cases caused by COVID-19 pneumonia, respiratory support is emphasized, including early oxygen therapy, prone position, airway management, etc. After the 10th edition of the diagnosis and treatment plan was issued and implemented, the society paid high attention to it. Guo Yanhong introduced that the core idea of the tenth version of the diagnosis and treatment plan is to manage and treat patients with COVID-19 infection in accordance with the conventional "Class B and Class B" infectious disease management method, which fully draws on the valuable experience of clinical treatment in the past three years. In terms of clinical treatment, not only the concept of co treatment of COVID-19 infection and basic diseases is emphasized, but also three points are emphasized: first, strengthen the gateway forward, and early intervention is also required for mild cases, especially for some elderly patients with basic diseases, strengthen the application of gateway forward measures, strengthen symptomatic and supportive treatment, and prevent mild cases from turning into severe cases; The second is to further standardize the diagnosis and treatment of critical patients, further improve the relevant early warning indicators, and implement timely treatment measures for critical patients as soon as possible by grasping the early warning indicators. The measures of oxygen therapy and prone position ventilation for severe patients were strengthened; Third, adhere to the combination of traditional Chinese and western medicine, especially pay attention to the unique role of traditional Chinese medicine in clinical treatment.
