Foot-and-mouth disease is a highly contagious viral disease caused by the foot-and-mouth virus. The disease occurs in cloven-hoofed animals and spreads through saliva, milk, manure and urine of infected animals. In addition, infection is possible through people, animals and materials that have been in contact with infected animals. On top of that foot and mouth disease is capable of airborne transmission. When foot-and-mouth disease is found, exports are halted and a stamping out protocol is implemented, causing major economic and emotional damage.
