Newcastle disease
Newcastle disease (pronounced: new-kah-suhl dih-zeez) is a highly contagious viral disease that affects a wide variety of bird species, both domestic and wild. The disease is named after Newcastle-upon-Tyne, England, where it was first identified in 1926.
Etymology
The term "Newcastle disease" was coined following an outbreak of the disease in Newcastle-upon-Tyne, England, in 1926. The disease is caused by a virus of the family Paramyxoviridae, genus Avulavirus, and is known to affect over 250 species of birds.
Symptoms
The symptoms of Newcastle disease vary widely, but can include respiratory distress, nervous signs, digestive problems, and a drop in egg production in laying birds. The severity of the disease can range from mild to severe, depending on the strain of the virus and the species of bird affected.
Transmission
Newcastle disease is primarily transmitted through direct contact with the feces and other bodily secretions of infected birds. It can also be spread indirectly through contaminated feed, water, equipment, and clothing.
Prevention and Control
Prevention and control of Newcastle disease primarily involves biosecurity measures, vaccination, and culling of infected birds. Biosecurity measures include regular cleaning and disinfection of premises and equipment, and limiting contact between domestic and wild birds.
