- Transmission
- The virus is believed to spread mainly through contact with infected birds or their droppings and feather dust, although the exact routes of transmission are not yet fully understood.
- Infected birds may carry and shed the virus without showing clinical signs, facilitating its spread.
- Treatment and Prevention:
