As far as clinical data are concerned, there are few sequelae in mild cases. However, the harm caused by the disease is still in the research and observation stage, and it is recommended to do personal protection to avoid infection. Mild cases of neocollins may only show symptoms such as low-grade fever, malaise, sore throat, cough, etc. Through regular treatment, patients can usually recover, and sequelae and residual lung function problems rarely occur. However, the epidemiologic period of new crowns is relatively short, and its impact on the human body needs to be observed and studied for a longer period of time. Since the long-term effects of the new crown on the human body are still unknown, it is recommended to get vaccinated in a timely manner in order to avoid infection and minimize the spread of the epidemic. Don’t be too anxious if you are infected with New Crown, just follow the doctor’s instructions for appropriate treatment and cooperate with the epidemic prevention and control.
