ABSTRACT
Objective To study the HIV-1 drug resistance transmission level in HIV infected persons receiving no antiviral therapy in Dehong prefecture of Yunnan province in 2015.Methods A total of 72 plasma samples were collected from recently reported HIV-infected persons aged 16-25 years in Dehong from January to July 2015 for drug resistance gene detection.Results Forty eight samples were successfully sequenced and analyzed.Among them,31.2% (15/48) were from Chinese,and 68.8% (33/48) were from Burmese.Based on pol sequences,HIV genotypes included URF (52.08%,25/48),CRF01_AE (16.67%,8/48),RF07_BC (10.42%,5/48),subtype B (6.25%,3/48),subtype C (6.25%,3/48),CRF57_BC (6.25%,3/48) and CRF08_BC (2.08%,1/48).One drug resistant mutation site to non-nucleoside analog reverse transcriptase inhibitor (NNRTI) and two drug resistant mutation site to nucleoside analog reverse transcriptase inhibitor (NRTI) were detected in four sequences.Based on the statistical method of HIV drug resistance threshold survey,the prevalence of HIV-1 drug resistant strain was 5%-15%.Conclusions The proportion of Burmese among newly reported HIV-infected individuals aged 16-25 years in Dehong in 2015 was higher.HIV-1 genetic diversity was found in Dehong.The prevalence of HIV-1 drug resistant strain had reached a moderate level in Dehong.
