Overview
Newcastle Disease, also known as Avian Newcastle Disease, is a highly contagious viral infection that primarily affects birds. It poses a significant threat to poultry and can impact both domestic and wild avian species. This disease is caused by the Avian Paramyxovirus-1 and can lead to severe respiratory and neurological symptoms.
Causes
Newcastle Disease is caused by the Avian Paramyxovirus-1. The virus is highly contagious and can spread rapidly among birds through direct contact with infected individuals, contaminated feed, water, equipment, and clothing.
