Reinfection can still occur after the new coronavirus has recovered. 1. Antibody status: Whether or not the body produces antibodies after the new coronavirus has recovered, and how strong or weak the antibodies are, may have an effect on whether or not reinfection occurs. If antibodies are produced, strong and long-lasting, reinfection will not occur in the short term. 2. Autoimmunity: If the patient has underlying diseases, poor immunity and weak resistance to the virus, reinfection may occur after the new coronavirus has recovered. 3. Virus mutation: If the virus has mutated, it may cause the antibody produced by the body to fail, resulting in mutated virus reproduction in the body, which may lead to reinfection of the new coronavirus after it has recovered. If the new coronavirus infection patient is well, you still need to do a good job of daily care, do not go to crowded places to avoid the virus reinfection.
