Long COVID Clinical Manifestations

Abstract

People are becoming more aware of the complications and sequelae that can occur as COVID-19 research advances. These complications and sequelae are referred to collectively as "Long COVID" (Long COVID-19). This paper summarizes the clinical manifestations of Long COVID and sequelae observed in the respiratory, neurological, circulatory, digestive, and other affected systems caused by Long COVID through an extensive review of clinical studies published in recent years, with the goal of raising awareness of the importance of Long COVID patients and informing the development of a comprehensive treatment system for COVID-19 patients.
