Infectious laryngotracheitis virus (ILT) causes acute respiratory disease in poultry and results in significant economic losses. This project aims to provide the Australian poultry industry with information and advice on critical points for future ILT control strategies in affected areas based on a series of epidemiological studies to identify flock management. This includes ILT vaccination program/s and geographic risk factors that might contribute to the incidence of ILT outbreaks and spread in broiler, pullet and layer flocks specifically in Victoria and NSW.
