@HealthRanger Mike, Dr Sabine Hazan says that she was able to detect SARS-CoV-2 in the stools of 100% of her patients. She even says that she identified 33 mutations. You might want to check this out further to have another side in your research for a sample of the virus. Would be great to have an interview between you and her trying to go through this question. Cheers.
