Coronavirus disease 2019 (COVID-19) is highly contagious and has a variety of clinical manifestations, it can affect a number of other organs in addition to the lungs, and liver injury may occur. Severe acute respiratory syndrome coronavirus 2 can cause liver injury through systemic inflammatory response syndrome, cytokine storms, ischemia-reperfusion injury, side effects of treatment drugs, and underlying liver disease and can attack liver cells directly via angiotensin-converting enzyme 2. Clinical studies have found that liver injury in COVID-19 patients mainly manifests as abnormal liver biochemical indicators, but there have been no reports of liver failure caused by this disease. The number of COVID-19 patients with liver injury is increasing, and the incidence of liver injury in COVID-19 patients with severe disease are higher than in patients with mild disease. Liver injury may be a risk factor, which worsens in patients with COVID-19, and hence it is necessary to pay attention to the occurrence of liver injury in the diagnosis and treatment of COVID-19.
