The majority of those who recover will have no residual effects, while a small percentage of infected individuals may experience residual effects such as decreased or loss of smell and taste, fatigue, and muscle aches and pains. Omicron is a mutated neocoronavirus and is one of the major globally prevalent neocoronavirus variants. Research data from various countries around the world show that although the symptoms of omicronjon infection are mild and similar to influenza, most patients are cured without significant sequelae. Some cured people may experience sequelae such as decreased or loss of smell and taste, fatigue, and muscle aches and pains, which may gradually diminish with exercise as well as over time. Because omikujon virus mainly attacks the respiratory system, some patients with severe or critical forms of the disease have more damage to the lungs and may still have pulmonary fibrosis and symptoms such as dyspnea after recovery. The above sequelae vary depending on the severity of the infection and the individual’s physical condition. Prompt medical consultation is recommended if there is any obvious discomfort.
