Leave shoes in U.K. or wash them upon your return and don t wear them around livestock for at least 3 months after returning. The virus can also be carried in uncooked or under-processed meat, fat and dairy products. It can survive in some of these products for over a year and can be mechanically transmitted by contaminated inanimate objects like clothing and shoes. The virus can survive in clothing for up to 46 days at room temperature. The classic signs are excessive salivation and drooling, as well as lameness due to the formation of vesicles in the mouth and on the feet.
Vesicular lesions can also occur on the teats of lactating animals and the snouts of affected swine.
The virus replicates itself in these vesicles and is released when they rupture. Other signs include fever, dullness, shivering, decreased milk production, shivering, lip smacking, kicking of the feet, weight loss and abortion. Infected animals produce large amounts of infective aerosols, which can be carried by air currents and the wind up to 40 miles.
