Discussion: At the mutation level,
K103N represents around the 50% of
NNRTI primary resistance in the last two periods while the remaining 50% was dominated by the
V108I mutation in the previous study and by the
G190A mutation in the present study.
Discussion: Interestingly, we found a high prevalence of
G190A, not previously reported in the region; and the absence of
V108I, found about equally often as
K103N in our previous study during 2003-2005.
