Emergence of the sequels under the COVID-19 epidemic

Abstract

Under the premise that Covid-19 virus is under better control with the time developed, more attention has being shifted to the sequelae of infecting the corona virus and how to prevent or deal with it. Covid-19 has led to about six hundred million confirmed cases worldwide as of September 12, 2022. It is crucial to get a better knowledge of the pathophysiology of COVID-19 given its global impact and the unknowable long-term consequences. The symptoms of corona virus are gradually being normalized for the whole population, and the attitude towards corona virus in Europe and the United States is gradually loosening, however, it has been proven that the illness during corona virus will last until two to three months after recovery, which is called post-COVID-19 syndrome, which is both physically and psychologically harmful. The main causes of this syndrome may be permanent damage to organs, residual virus in the body, and excessive immune response. Nowadays, the only thing that can be accomplished is to relieve the symptoms of the disease, but unfortunately there is no complete cure for it with the current clinical technology. At present, the epidemic situation continues in the world. Clinicians should improve their understanding of this disease.
