Evidence has shown that the SARS-CoV-2 can be found in faeces, and that stool samples can remain positive for the virus even when it is no longer detectable in the respiratory tract, suggesting the possibility of a faecal–oral route of transmission.9 This concept is supported by the presence of gastrointestinal symptoms in some patients affected by COVID-19.10 Another relevant issue is that faecal microbiota transplantation is not classified in the same way worldwide, as some countries regulate these transplants as a drug (eg, the USA, the UK, and France), some as a tissue (eg, Italy), and others do not provide specific regulation (eg, Australia).8 This discrepancy results in a confusing scenario, in which some countries will apply rules for human cells, tissues, or cellular or tissue-based products, and others will not, potentially contributing to the spread of the infection.
