claim: no presence of sars-cov-2 viral rna in faecal samples
evidence_1: further research into the viability and infectivity of sars-cov-2 in faeces is required.", "patients with suspected sars-cov-2 were confirmed after two sequential positive respiratory tract sample results.", "our data suggest the possibility of extended duration of viral shedding in faeces, for nearly 5 weeks after the patients' respiratory samples tested negative for sars-cov-2 rna.", "here, we observed that for over half of patients, their faecal samples remained positive for sars-cov-2 rna for a mean of 11·2 days after respiratory tract samples became negative for sars-cov-2 rna, implying that the virus is actively replicating in the patient's gastrointestinal tract and that faecaloral transmission could occur after viral clearance in the respiratory tract."
