Mechanical transmission by fomites and living (e.g., animal) vectors is important for this virus. Airborne transmission can occur under favorable climatic conditions, with some viruses potentially spreading long distances, particularly over water. In 1981, one viral strain apparently traveled more than 250 km (155 miles) from Brittany, France to the Isle of Wight, U.K. However, aerosolized FMD viruses are rarely thought to travel more than 10 km (approx. 6 miles) over land
