Abstract
The outbreak of a novel coronavirus disease 2019 (COVID-19) began in China in December 2019 and spread worldwide. The current review summarized clinical, radiological, and laboratory findings of patients infected with COVID‐19. Based on many studies, the main symptoms of the disease include respiratory symptoms, fever, cough, and dyspnea; there is also a wide range of biochemical, hematological, and radiological changes in the patients. The signs (or symptoms) and other variables in the early stage or the mild stage of the disease appear in a highly heterogeneous and non-specific manner. Identifying the clinical and paraclinical symptoms of COVID-19 can be effective in controlling it.
