The Foot-and-mouth Disease

In Great Britain, million sheep were burned because of the foot-and-mouth disease. This germ is very contagious! However, it does not seem dangerous for the humankind. But the animals have fever and aphta in the mouth. After the episode of the mad cow, the stockbreeders are still affected. If just one sheep carries the virus, all the other animals are to be killed because this microbe can cross 200 kilometres per minute!
