Foot-and-mouth is a contagious viral disease that affects cloven-hoofed animals such as cattle, sheep, and pigs, causing fever, blisters, and sores on their feet and mouths. There are several synonyms for foot-and-mouth, including hoof-and-mouth disease, aphthous fever, and vesicular stomatitis. In some regions, it is also known as cattle plague or mouth blight. The disease can have a significant impact on the livestock industry, causing loss of productivity and even death in severe cases. Due to its highly contagious nature, strict measures are usually imposed to control its spread, such as quarantine and culling of infected animals.
