All patients presented with a fever. Other symptoms were cough, sore throat, fatigue and diarrhoea. Two patients had positive anal swabs:
- Patient 8 had three positive results in blood, anal swab and oropharyngeal swab on the 3rd day after onset.

What did they do?
Samples were collected from nine patients diagnosed with COVID-19. Patients’ demographic data and clinical characteristics were recorded. Urine, blood, anal swabs and oropharyngeal swabs from SARS-CoV-2 RNA level by quantitative real-time polymerase chain reaction (qRT-PCR).
