Since no one has any idea how the disease began all the animals on surrounding farms must be destroyed too to try and stop its spread. But the disease begins showing up in other places around the country too. You were walking with your dog in Galway and a child asked to pet your dog. The virus got on his clothes. Within months the country is having to destroy all its livestock.
Farmers are in financial ruin.
Tourism must grind to a halt to prevent further spread of the disease outside Ireland. Ireland loses its excellent reputation as a disease free state and it will take years, if ever, to reclaim it. In this scenerio, which as I said is exaggerated, you have unlnowingly brought a country to its economical knees. Six months would be the outside any disease would take to incubate or die out. This isn't a personal attack on any one or their pet.
