Novel coronavirus infection can be cured, but there is no vaccine to prevent it, and there is no specific medicine to treat it. In mild cases, the symptoms of novel coronavirus infection are similar to those of common cold and influenza, with atypical clinical manifestations, including respiratory symptoms such as dyspnea, shortness of breath, gastrointestinal nausea and vomiting, diarrhea, etc., which are self-limiting and can be relieved by themselves; in severe cases, acute respiratory failure, ARDS, sepsis and other serious complications can occur, requiring joint consultation and comprehensive treatment by various hospital departments.
