abstract = "Since the introduction of the universal hepatitis B vaccination program in Russia in 2001, the incidence of acute hepatitis B has dropped from 35.3 to 0.3 cases per 100 thousand people annually, while that of chronic hepatitis B (including new HBV carriers) has declined from 105.6 to 16.8 cases per 100 thousand. The proportion of HBsAg-positive carriers in the general population has decreased from 1.8–4.6% in the 1990s to 0.8 ± 0.1% by 2020. An important question remains whether any HBV genetic variants have gained an evolutionary advantage under this selective pressure. Aim. To evaluate changes in the spectrum of genetic and serological variants of HBV circulating in five regions of Russia—Chukotka, Tyva, Yakutia, Moscow, and Khabarovsk—over 10 to 20 years of observation. Results and Discussion. In Chukotka, the proportion of the dominant subgenotype D3 (mainly the HBsAg subtype ayw2) fluctuated from 44.3 (in 1997) to 58.1% (2008), C2 (adrq+) from 16.4 (1997) to 37.1% (2008), D2 (ayw3) from 3.2 (2008) to 23% (1997), D1 (ayw2) from 1.6 (2008) to 11.5% (1997), and A2 (adw2) from 0 (2008) to 4.9% (1997). In Tyva, the prevalence of D1 ranged from 57.4 (2021) to 67.6% (2008–2009), D2 from 13.2 (2008–2009) to 38.3% (2021), D3 from 0 (2021) to 16.2% (2008–2009), and A2 from 2.9 (2008–2009) to 4.3% (2021). In Yakutia, D3 was from 24.1 (2022) to 45.5% (2004–2008), A2 from 36.8 (2018) to 43.1% (2022), D2 from 4.5 (2004–2008) to 13.1% (2022), C2 from 5.3 (2018) to 11.7% (2022), and D1 from 4.5 (2004–2008) to 6.6% (2022). In Moscow, D3 was from 25 (2020) to 49.1 (2008–2009), D1 from 16.4 (2008–2009) to 41.2% (2020), D2 from 24.3 (2020) to 25.5% (2008–2009), and A2 from 5.3 (2008–2009) to 8.1% (2020). Finally, in Khabarovsk, the proportion of D2 ranged from 23.1 (2021) to 46.9% (2003–2008), D3 from 27.8 (2015) to 40.6% (2003–2008), D1 from 3.1 (2003–2008) to 24.6% (2021), A2 from 5.6 (2015) to 10.8% (2021), and C2 from 3.1 (2003–2008, 2021) to 5.6% (2015). Despite shifts in the proportions of distinct variants, the overall spectrum of HBV types circulating within each region has remained largely unchanged over the 10- to 20-year observation period.
