Draft:Blue Eye Disease

Other names: La-Piedad-Michoacan Paramyxovirus Infection

Description

Blue eye disease is a viral disease that is commonly identified by encephalitis which is inflammation of the brain, pneumonia, and respiratory diseases in piglets. It also includes reproductive failure in adult pigs, and rarely identifies with corneal opacity which is an eye disorder where the cornea becomes scarred.

Etiology

Blue eye disease is caused by the porcine rubulavirus where the disease first emerged in 1980 throughout parts of Mexico including La Piedad, Michoacan, Jalisco and Guanajuato.

Location

Blue eye disease usually occurs in swine from areas of Australia, Israel, Japan, and parts of North America including Canada and Mexico where it first originated.

Clinical Signs

Blue eye disease typically begins in piglets that are between 2-21 days old. It usually begins with a sudden onset of fever, arched back, or depression. The disease then progresses with neurologic symptoms including weakness, ataxia, muscle tremors, abnormal posture, and rigidity to their hind legs.
