Omicron is one of the mutated strains of the new coronavirus, and infection can be treated with antiviral drugs, monoclonal antibodies, immunoglobulins, glucocorticoids, and interleukin 6 inhibitors. 1. Antiviral drugs: According to the current standard of care, the recommended antiviral drug is ritonavir tablets, which are used in cases of new onset of illness within 5 days and in adults and adolescents with common type of infection who are at risk of progression to severe type. 2. Monoclonal antibodies: Currently, Ambavizumab/Romivizumab injections are available, which have antiviral effects, and are indicated for adults and adolescents with mild and common forms of the disease with high risk factors for progression to severe forms. 3. Immunoglobulin: COVID-19 human immunoglobulin can be used, in the early stages, for patients with high viral loads, high-risk factors, and rapid progression of the disease, but the total number of uses should not exceed five. 4. Glucocorticoid: It is suitable for heavy and critical patients with severe disease, body hypoxia, and obvious inflammatory reaction, and is usually treated with dexamethasone or homeoprednisone. 5. Interleukin 6 inhibitors: such as tolizumab, can be used in heavy, critical and significantly elevated interleukin 6 levels. It should be noted that once infected with Omicron, you should immediately go to a designated hospital for medical treatment, isolation treatment, not to use their own medication without authorization, and not to hide the history of the disease.
