Abstract

Patients with COVID-19 disease can present with a wide range of symptoms, from asymptomatic to critical illness and death. Most patients are present with asymptomatic or mild illness. The most common symptoms of COVID-19 disease are cough, fever, headache, and fatigue. Severe disease is more common among elderly patients and in patients with underlying medical conditions. Elderly patients can present with non-typical symptoms or have few symptoms, even when they have a severe illness. Differences in the prevalence of symptoms as well as disease severity have been observed when comparing emerging COVID-19 variants with earlier variants. Furthermore, patients who have been immunized or have recovered from a previous illness are less likely to experience severe symptoms, be hospitalized, or die. Although COVID-19 is predominantly a disease of lung parenchyma, extrapulmonary manifestations are common.
