Abstract
In 2020, the world suffered an epidemic of a new coronavirus infection, after which it became obvious that the consequences of this disease persist for a long time after the recovery, perhaps, for several months. This complication was called post-COVID-19 syndrome and was recognized by the World Health Organization, which was reflected in the Delphi Consensus on October 6, 2021. The clinical characteristics of this disease include a significant number of immunological manifestations, including fever, arthralgia, myalgia, flu-like symptoms, as well as autoimmune diseases manifestation. These symptoms may allude the autoimmune genesis of the COVID-19 complications. This mini-review summarizes the current understanding of the systemic manifestations of COVID-19 and the possible role of impaired immune function in the pathogenesis of post-COVID-19 syndrome.
