The worldwide research on autoimmunity after covid is still ongoing and it's unclear for large demographic. but a study conducted on 147 covid patients and 48 normal individuals showed that more than 50% of covid patients showed at least one type of autoimmune antibody circulating. In contrast to the normal individuals, it was only 15%. Also, more than 20% of these covid patients developed newer autoantibodies after when the disease progressed.
