Detection of the SARS-CoV-2 in different biologic specimens from
positive patients with COVID-19, in Northern Italy
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 were sometimes
negative raise the attention to collect other clinical specimens.
SARS-CoV-2 was shown in 10.3%rectal swabs (RS), 7.7% plasma,1% urine,
0% feces from 143NS positive patients. Potential infection by fluids
different from respiratory secretion is possible but unlikely.
