The comparative prevalence of HIV-1 genetic variants in Kazakhstan as reported in 2004,⁶ in 2007,⁷ and in the present study. The data published in 2004 resulted from the samples collected in Pavlodar, Karaganda, and Shymkent in 2000–2001. The publication of 2007 was based on the study of the strains found in different regions including Almaty in 2001–2003. The present study involved all the regions investigated before. The chart shows the ratio of the main HIV-1 variants—IDU-A and CRF02_AG—in the regions where the greatest numbers of samples were studied in 2009–2013.
