After recovering from omikron infection, it may not be easy to relapse in the short term, but in the long term, there is a possibility of being re-infected with the new coronavirus. Omicron is a mutated strain of the Neocoronavirus. After recovery from Omicron infection, the human body will produce neutralizing antibodies against Omicron, which can play a certain protective role for the human body in the short term, and so it is not easy to be re-infected in the short term. However, after Omicron is cured, the concentration of specific antibodies in the human body is decreasing with the prolongation of time, and the protective power becomes weaker; moreover, the new coronavirus itself is evolving, and new mutated strains may appear, and the effect of antibodies on it may weaken, and it may be re-infected and cause symptoms. Therefore, even after the omicron infection is cured, it is still necessary to cooperate with the epidemic prevention requirements, such as not gathering, wearing masks when going out, and washing hands frequently.
