Overview
Newcastle disease is a highly contagious viral infection caused by the avian paramyxovirus-1. It primarily affects birds, including poultry and pet birds, and can lead to severe respiratory, digestive, and neurological symptoms. While rare in humans, the virus can cause mild flu-like symptoms.
Causes
The disease is caused by exposure to the Newcastle disease virus (NDV), which can spread through direct contact with infected birds, contaminated feed, water, equipment, or clothing.
