Makes me wonder if it might be possible to deliberately infect body regions where the virus has a low chance of reaching the lung. Could the virus populate (until sufficient immune reaction) the lower intestine if put there, and not spread elsewhere due to the unambiguously directed flow down there (as opposed to bidirectional flow in the respiratory system) or would it be transmitted elsewhere nonetheless through the blood stream? Is this something that can and is checked with animal models?
