Abstract

  The world is still facing the coronavirus disease 2019 (COVID-19) pandemic caused by coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), since it first appeared in Wuhan, China, in December 2019. The virus primarily affects the respiratory system, but increasing evidence indicates that SARS-CoV-2 can affect multiple organ systems and causes several complications. The risk factors for disease severity and complications of COVID-19 include cancer, cerebrovascular disease, chronic kidney disease, chronic obstructive pulmonary disease (COPD), and other lung diseases, diabetes mellitus, down syndrome, heart conditions, human immunodeficiency virus (HIV) infection, neurologic conditions, obesity, pregnancy, smoking, sickle cell disease, solid organ or blood stem cell transplantation, substance use disorders, use of corticosteroids or other immunosuppressive medications. Since older people have one or more coexisting medical conditions, they are probably at the highest risk for fatal COVID-19 infections. COVID-19 disease severity can range from mild to critical, with the majority having only mild disease. The most common complication of this disease is acute respiratory distress syndrome (ARDS). Other complications include cardiovascular, renal, neurologic, thrombotic complications, liver injury, as well as bacterial, viral, and fungal coinfections. This review summarizes the current understanding of the risk factors, the severity of COVID-19 infection, and the most common complications of this disease.
