Infection with Neocoronavirus is mostly a mild or asymptomatic infection with no sequelae. However, severe cases may have sequelae such as decreased cardiopulmonary function and neurological symptoms. 1. Decline in cardiopulmonary function: Neocoronavirus mainly attacks human lung cells and cardiac muscle cells. In critically ill patients, interstitial lung injury will be caused by the new coronavirus attacking the lungs, which will lead to myocardial hypoxic injury and enhanced inflammatory state due to hypoxia, which may lead to cardiac complications such as arrhythmia. 2. Neurological symptoms: Many patients with severe diseases will have neurological symptoms during the disease, and neurological abnormalities will also occur after the recovery of the new crown, the most common is the sense of smell, taste loss, and other neurological symptoms such as cognitive deficits, tremor, sensory deficits and other neurological symptoms may also appear. However, it is not a given that there will be sequelae after infection with Neocoronavirus. If infected with Neocoronavirus, it is important to actively seek help, not to hide it, and to take good personal precautions in order to avoid spreading and transmission of the disease.
