Data are n (%) of subtypes/CRFs, unless otherwise indicated. CRF, circulating recombinant form.
aHIV subtypes were determined from the pol sequences, using the REGA HIV-1 subtyping algorithm version 2.0 (http://dbpartners.stanford.edu/RegaSubtyping) and/or Stanford HIV drug resistance database (http://hivdb.stanford.edu).
bThe collaborating sites in Philippines, South Korea and Indonesia had not yet provided sequence data at time of the current analysis.
