OBJECTIVES: Coronavirus Disease-19 (COVID-19) is a respiratory infection
characterized by the main symptoms of pneumonia and fever. It is caused by the
novel coronavirus severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2),
which is known to spread via respiratory droplets. We aimed to determine the rate
and likelihood of SARS-CoV-2 transmission from COVID-19 patients through
non-respiratory routes. METHODS: Serum, urine, and stool samples were collected
from 74 hospitalized patients diagnosed with COVID-19 based on the detection of
SARS-CoV-2 in respiratory samples. The SARS-CoV-2 RNA genome was extracted from
each specimen and real-time reverse transcription polymerase chain reaction
performed. CaCo-2 cells were inoculated with the specimens containing the
SARS-COV-2 genome, and subcultured for virus isolation. After culturing, viral
replication in the cell supernatant was assessed. RESULTS: Of the samples
collected from 74 COVID-19 patients, SARS-CoV-2 was detected in 15 serum, urine,
or stool samples. The virus detection rate in the serum, urine, and stool samples
were 2.8% (9/323), 0.8% (2/247), and 10.1% (13/129), and the mean viral load was
1,210 ± 1,861, 79 ± 30, and 3,176 ± 7,208 copy/?L, respectively. However, the
SARS-CoV-2 was not isolated by the culture method from the samples that tested
positive for the SARS-CoV-2 gene. CONCLUSION: While the virus remained detectable
in the respiratory samples of COVID-19 patients for several days after
hospitalization, its detection in the serum, urine, and stool samples was
intermittent. Since the virus could not be isolated from the SARS-COV-2-positive
samples, the risk of viral transmission via stool and urine is expected to be
low.
