The sequelae of neocoronavirus infection are unclear and vary from person to person, with respiratory, neurologic, cardiovascular, and hepatic and renal damage being the main possible sequelae. Neocoronavirus pneumonia is an acute respiratory infectious disease caused by a novel coronavirus infection. 1. Respiratory system: As the virus invades the respiratory system, resulting in severe lung damage, patients may develop pulmonary fibrosis with chest tightness, dyspnea, weakness after activity and other uncomfortable symptoms. 2. Neurological symptoms: Invasion of brain cells and tissues causes chronic nerve damage, headache, neuralgia, memory loss, and loss of taste and smell. 3. Cardiovascular system: New coronavirus may cause serious damage to the cardiovascular system, such as chest tightness, chest pain, palpitations and myocardial damage. 4. Renal system: New coronavirus can also lead to abnormalities in liver and kidney function, acute kidney injury, elevated creatinine and urinary nitrogen, seriously affecting health. It is worth noting that as the neocoronavirus continues to mutate, the sequelae and severity of neocoronavirus pneumonia vary from person to person. The evidence on the above sequelae is not yet sufficient and further studies are needed. Take good personal precautions in daily life, get vaccinated in time, and consult a doctor promptly if symptoms such as fever and cough occur.
