Some studies have shown that some patients with Omicron NeoCollins virus infection have sequelae after cure, which may include cardiopulmonary hypoplasia and neuropsychiatric symptoms. 1. Cardiopulmonary hypoplasia: It is mainly related to the virus attacking the lung and cardiac muscle cells resulting in ischemia of the lung muscles and cardiac muscle. Severe and critically ill patients may develop pulmonary fibrosis, and after cure, patients may still have symptoms such as decreased lung function; patients may also develop cardiac sequelae such as arrhythmia, coronary heart disease, and heart failure. 2. Neuropsychiatric symptoms: some patients develop mental problems such as fatigue, anxiety, depression and sleep difficulties after cure. Whether or not there are new sequelae of Omicron is not yet fully verified due to the short time of its dissemination.
