Overview
Newcastle disease is a highly contagious viral infection in birds caused by the avian paramyxovirus-1. It affects a wide range of domestic and wild avian species, causing severe respiratory, digestive, and neurological symptoms. Due to its contagious nature, it poses significant risks to poultry and pet birds.
Causes
Newcastle disease is caused by the avian paramyxovirus-1. It spreads through direct contact with infected birds, contaminated equipment, feed, water, and even through the air in close quarters.
