Reanalysis of the HIV-1 Circulating Recombinant Form A/E (CRF01_AE): Evidence of A/E/G Recombination

Circulating recombinant form (CRF) 01_AE caused an extensive HIV-1 epidemic in Thailand and Southeast Asia. Reanalysis of the recombination pattern of CRF01_AE suggested a more complicated pattern of mosaicism consisting of subtypes A, G, and E. These findings provide evidence that CRF01_AE originated from recombination between at least three different subtypes.
