Abstract

Coronavirus disease 2019 is an infection caused by severe acute respiratory syndrome coronavirus 2. Many symptomatic patients have influenza-like symptoms such as fever, respiratory symptoms (cough, sore throat, and nasal discharge), headache, and malaise. In some cases, oxygen is required within a week of onset, and in more severe cases, the patient is admitted to the intensive care unit after around 10 days of onset. In the COVIREGI-JP registry of hospitalized patients with coronavirus disease 2019, patients with renal dysfunction, liver disease, obesity, hyperlipidemia, hypertension, and diabetes tended to be more severely ill after hospitalization than patients without comorbidities. It has also become clear that symptoms can persist even after the acute phase has passed.

Keywords: clinical manifestation; coronavirus disease 2019; severe acute respiratory syndrome coronavirus 2.
