Peculiarities of the Spread of HIV infection among Urban and Rural Residents of the Tyumen Region

Relevance. The geographical spread of HIV infection among the population of various administrative territories is very heterogeneous. The Tyumen region, due to its vast territory and the significant remoteness of some areas from the regional center, is of particular interest in the framework of considering the territorial features of the spread of HIV.

Aims. To consider peculiarities of the spread of hiv infection among urban and rural residents of the Tyumen region in 1993–2019.

Materials & Methods. Statistical data of the «Center for the Prevention and Control of AIDS» in the period from 1993 to 2019, annual form No. 61 «Information on the contingents of HIV patients» for 2006–2019, materials of the state report «On the sanitary and epidemiological situation in the Tyumen region» for 2013–2019. Methods of epidemiological observation were used in the work: analytical and descriptive-evaluative with the use of methods of retrospective and operational analysis and statistical methods.

Results and Discussions. A specific feature of the spread of HIV infection among urban and rural residents is the tendency to exceed the regional incidence rate in a number of territories. Analysis of epidemiological data for the period under review showed that all territories of the region are involved in the epidemiological process of HIV infection, and in a number of territories the prevalence rate exceeds the average Russian level. HIV prevalence as of December 31, 2019 was 728.2 per 100 thousand people in Russia. In 17 administrative territories of the Tyumen region the infection rate is higher than the national average level and is per 100 thousand population in the city of Tobolsk – 1903.3, in the districts of Uvat – 1486.2, Tobolsk – 1440.5, Nizhnetavda – 1354.9, Tyumen – 1344.1, Yalutorovsk – 1327.6), in the city. Tyumen – 1249.3, in the districts: Vagay – 1195.2, Zavodoukovsky – 1119.2, in Ishim – 951.8, in the districts: Yarkovsky – 889.6, Vikulovsky – 881.3, Yurginsky – 846.9, Ishimsky district – 842.1, Aromashevsky – 851.6, Isetovsky – 754.4, Uporovsky district – 734.7.

Conclusions. The HIV epidemic in the Tyumen region is determined by its economic and geographic location and by the presence of exceptional epidemiologically significant prerequisites for the intensive spread of HIV, in particular, by the routes through which large quantities of drugs are illegally transported (drug trafficking from the northeast).
