Objective. Evaluation of the features of the territorial distribution of the urogenital chlamydiosis incidence in the Russian Federation.
Materials and methods. The official statistics of the Russian Federation on urogenital chlamydiosis (UC) and its territorial distribution for the period 2005–2021 were analyzed.
Results. The UC incidence is characterized by a decreasing trend. In 2021, it was 17.8 per 100 thousand population in the Russian Federation. The average annual rate of decline for the period studied is -9.86%. Urogenital chlamydial infection is the second most common sexually transmitted infection after trichomoniasis. The decrease in the UC incidence in the constituent entities of the Russian Federation is irregular. In 2021, the highest rates were registered in the Far Eastern (35.1) and Northwestern (25.4) Federal Districts, and the lowest - in the Southern Federal District (9.9). The epidemic situation in the Russian Federation and European countries is different. Thus, in 2019, in Denmark, Norway, England and Finland, the UC incidence rates were higher than in the Russian Federation by 25, 21, 16, 12 times, respectively, and tended to increase. A uniform territorial distribution of morbidity was noted: in 9 subjects of the Russian Federation it was consistently low and in 9 subjects - consistently high. The correlation coefficient of morbidity with the availability of doctors in the population is 0.45, which may be associated with the inability to contact specialists. This leads to a decrease in the registration of UC cases, and not to reduce morbidity.
Conclusion. UC incidence in the Russian Federation for 2005–2021 had a downward trend. Regions with persistently low and persistently high incidence rates are clearly distinguished. Official statistics in the Russian Federation probably do not reflect the true picture of morbidity.
