The Covid-19 virus can also affect the small bowel, not just the lungs. The cells in the small bowel have receptors that the virus can attach to. Early symptoms of Covid-19 can show up in the gut. The virus can be released in the airway and then move to the gut. Studies in mice have shown damage to the small bowel from the virus. The small bowel has a protein that helps the virus attach to cells. This information can help us understand how the virus interacts with our bodies.
