Patients infected with omicron will have antibodies in their bodies after they have healed themselves. Omicron is a mutated strain of the novel coronavirus that causes novel coronavirus pneumonia. For most asymptomatic infections or mild cases, individuals can recover on their own. However, regardless of one’s condition, once infected with omicron, the body’s internal immune system produces specific antibodies that help the body effectively remove the pathogenic microorganisms that have invaded the body. Therefore, after recovering from omicron infection, there are still some antibodies in the body, the existence of which can to a certain extent effectively reduce the chances of re-infection with new crown pneumonia. The antibodies that the body produces to protect itself against the virus do not last forever, and will gradually decrease over time, so individuals need to do a good job of preventing and treating the disease even after they have recovered from it. If you have symptoms related to the new crown virus infection, you should pay attention to timely medical isolation treatment. Tip: “New coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
