Highlights • SARS-CoV-2 viral loads peak from upper respiratory tract samples around symptom onset.• Viral loads from sputum samples may be higher than upper respiratory tract samples.• Viral loads appear to be similar between asymptomatic and symptomatic patients.• The prolonged virus detection in stool samples has unclear clinical significance.• Patients may not be infectious for the entire duration of virus detection.

- Airborne transmission of respiratory viruses (2021, result): “Although some studies suggest that airborne transmission is not an efficient route, particularly for asymptomatic andmildly symptomatic individuals who likely have low viral loads in their saliva (55), the viral load in presymptomatic individuals is comparable to that of symptomatic patients (174, 1”
