▪ Simian Immunodeficiency Virus– Multiple trans-specific crossover events over the past 200 years
(recent)▪ Largely associated with bushmeat practices
▪ Established foothold with increase in population and travel
– Crossover events occurred enough to establish HIV-1 and HIV-2, and multiple subgroups therein.▪ Demonstrates occurrence is not rare.
– Partly due to the high mutation rate of HIV/SIV, CRF ability▪ Imparts ability to develop ART resistance/hybridize ART resistance.
