The new coronavirus in the body usually cannot be excreted by itself, and it mainly relies on antiviral, immunization, anticoagulation, Chinese medicine assistance and other treatments to kill the new coronavirus. 1. Antiviral, mainly using antiviral drugs such as ritonavir and ambavizumab to reduce the viral activity, so as to gradually kill the new coronavirus. 2. Immunotherapy, using glucocorticosteroids such as methylprednisolone, interleukin 6 inhibitors such as tolizumab, etc., to improve the oxygenation index and the general status of critically infected patients. 3. Anticoagulation therapy, mainly using low molecular heparin, is mainly aimed at preventing thrombotic events. 4. Traditional Chinese medicine (TCM) adjuvant therapy, mainly used for mild and asymptomatic infected patients, accompanied by mild fatigue and other symptoms, using Lianhua Qingdian capsule and so on for adjuvant therapy. The selection of specific drugs should be in accordance with the doctor’s instructions, and should not be used on one’s own.
