The prevalence of HIV infection in pregnant women during the study period tended to increase annually from 656.4 to 857.8 per 100 thousand pregnancies. The prevalence of HIV infection among pregnant women who have completed pregnancy by childbirth increased from 650.7 to 795.0 per 100 thousand women who gave birth.

The proportion of newly diagnosed HIV infections among pregnant women in the structure of the overall HIV incidence has decreased from 7.92% to 6.03%. The main route of HIV infection of pregnant women was sexual, the average for the period of its specific weight was 92.6±4.0%, the parenteral pathway accounted for 7.4±4.0%. There is a steady change in the age structure of HIV-infected pregnant women with first time established diagnosis, towards the age group of 21-30 years.
