No patients harboured PI DRMs, 5.33% (12\/225) of the patients harboured NRTI DRMs and 11.11% (25\/225) of the patients harboured NNRTI DRMs. The overall prevalence of strains with ADR was 51.43% (18\/35), while the prevalence of strains with PDR was 2.63% (5\/190). A total of 20 transmission networks, involving 25.78% (58\/225) database-derived sequences, were identified. The networks ranged in size from 2 to 10 individuals, of which most (55.00%, 11\/20) were made up of two individuals. Among the 225 study subjects, 9.78% (22\/225) had 1 link and 16.00% (36\/225) had \u22652 links.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The overall prevalence of CRF59_01B strains with ADR among the ART-experienced patients was high.
