Vesicular exanthemaVesicular exanthema of pigs closely resembles foot-and-mouth disease in these animals. The virus causing the disease belongs to the genus Calicivirus in the family Caliciviridae. The disease is not communicable to cattle and at present this is the only factor which distinguishes it from the foot-and-mouth disease. The disease is extinct in swine now, although the virus is present in marine mammals. It is not reported in India.
