Most patients with confirmed COVID-19 have symptoms of acute respiratory illness. However, various other symptoms have been associated with COVID-19, and symptom profiles have varied by SARS-CoV-2 variants; this list is not inclusive of all reported symptoms and the percentages are approximates based on findings with early Omicron variants. These symptoms are also not specific for COVID-19, and the predictive value of a single symptom in the diagnosis of COVID-19 is uncertain.
