The recent status of ILT in Australia was used here as a model to evaluate the evolution of the ILT viruses (ILTVs).
- ss="label">•
Many of the recent outbreaks were caused by two recombinant ILTVs with higher virulence and replication capacity.
- ss="label">•
Yet another recombinant ILTV emerged and appeared to become a predominant genotype in one state of the country.

In another state however, another recombinant virus became the predominant virus, replacing the local historical strain.

ILTV is fast evolving towards a greater transmissibility and therefore greater capacity to spread into ILTV-free areas.
