The new coronavirus refers to the new coronavirus pneumonia, whether the new coronavirus pneumonia is prone to recur after cure needs to be judged according to the specific situation. New coronavirus pneumonia is not likely to recur in the short term after treatment. At this time, the body has antibodies to the new coronavirus, which can prevent and resist the new coronavirus to a certain extent. If the activity of the protective antibody decreases or the antibody disappears, there will be a relapse. If the body has not been cleared of the new coronavirus, there is also a possibility of re-positive. It is recommended not to relax vigilance after the treatment of novel coronavirus pneumonia, observe your symptoms, and take nucleic acid test regularly to observe whether the novel coronavirus is cleared. Currently, there is no clear conclusion on the duration of the protective antibodies against the novel coronavirus, so it is necessary to take good care of yourself and protect yourself after the cure of the novel coronavirus pneumonia. Avoid going to crowded places to prevent infection by the new coronavirus. Tip: In this article, the terms “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
