That implies the disease was probably introduced for some time before it was detected. Laboratory tests are required to confirm the disease. It has an incubation period of about a week. The CFIA has issued a ban on swine embryos, swine semen, live swine, pork products and by-products. It does not affect horses.
Blisters occur on the nose, tongue, lips, between the toes, above the hooves and on the teats.
Animals cannot eat properly when their tongues and lips are affected. Calves and piglets cannot nurse because the teats are sore. Foot lesions are accompanied by acute lameness and reluctance to move. Additional signs include fever, depression, loss of appetite or milk production. Infected animals must be destroyed immediately to stop the virus.
