Foot and Mouth Disease

swineFoot-and-mouth (FMD) disease is a severe, highly contagious viral disease of cattle and swine. It also affects sheep, goats, deer, and other cloven-hooved ruminants. FMD is not a threat to people and no human health risks are associated with the disease. FMD is caused by a virus. Signs of illness can appear after an incubation period of 1 to 8 days, but often develop within 3 days. There are seven known types and more than 60 subtypes of the FMD virus. Vesicles (blisters) followed by erosions in the mouth or on the feet and the resulting excessive salivation or lameness are the best known signs of the disease. FMD, however, can be confused with several similar diseases, including vesicular stomatitis and swine vesicular disease. Whenever mouth or feet blisters or other typical signs are observed and reported, laboratory tests must be completed to determine whether the disease causing them is FMD.
