[2] The analysis also showed that KoRV was closely related to the highly pathogenic gibbon ape leukemia virus (GALV).

[5] Research has also shown that some populations of koalas, particularly an isolated colony on Kangaroo Island do not appear to have the endogenous form of the retrovirus.

Prevalence of KoRV (and KIDS) in Australian koala populations suggests a trend spreading from the north down to the south of Australia.

Therefore, KoRVB will remain exogenous and more pathogenic than KoRVA, because the deleterious effects it causes in its hosts will not be selected against to the extent they would in a virus capable of integrating into the germ line.

[9] It is thought that further studying KoRV will allow valuable insight into how endogenous retroviruses develop, evolve, and incorporate themselves into mammalian genomes.
