Upper Respiratory Tract Levels of Severe Acute Respiratory Syndrome Coronavirus 2 RNA and Duration of Viral RNA Shedding Do Not Differ Between Patients With Mild and Severe/Critical Coronavirus Disease 2019 `yilmaz2020upper`

The authors reported longitudinal viral RNA loads from the nasopharynx/oropharynx in patients with mild and severe/critical coronavirus disease 2019 (COVID-19). They also investigated whether the duration of symptoms correlated with the duration of viral RNA shedding. A total of 56 patients were included.
