Coronavirus disease 2019 (COVID-19) diagnosis is based on molecular detection of SARS-CoV-2 in respiratory samples such as nasal swab (NS). However, the evidence that NS in patients with pneumonia was sometimes negative raises the attention to collect other clinical specimens. SARS-CoV-2 was shown in 10.3% rectal swabs (RS), 7.7% plasma, 1% urine, and 0% feces from 143 NS-positive patients. Potential infection by fluids different from respiratory secretion is possible but unlikely.
