It is one of the most highly contagious diseases known. It can e carried from place to place not only by the animals susceptible to it. but also by other animals. on clothing. trucks. hay. straw. and. according to some belief. by birds. Canadian authorities are now investigating the possibility that the current outbreak was brought on by infection from the clothes of an immigrant dairyman who came to Canada recently from Germany and who had worked in Germany with a herd of infected cattle. Foot and mouth disease can be controlled only by the slaughter and burial of the diseased animals and by the disinfection of the premises where they have been kept. Even so. the virus may live in the ground for months or even years. awaiting a favorable opportunity to strike again.
