The aim of the review was to characterize the epidemiological situation on ixodic tick-borne borreliosis (ITBB) in the constituent entities of the Russian Federation in 2022, to forecast the development of the ITBB epidemic process in 2023 based on the analysis of its trends in the period of 2013–2022. In total, 7 264 cases of ITBB were registered in the Russian Federation in 2022, which is 1.9 times higher than the 2021-value. In all regions in 2022, after a sharp decrease in the level of registered morbidity during the “covid” phase of 2020–2021, there was an incidence raise to the pre-pandemic level. During 2013–2022, distinctive features of the trends in the development of the ITBB epidemic process in the territories of varying degree of epidemic hazard were retained. A downward tendency in the incidence rates was revealed in 14 out of 18 entities with a long-term average annual incidence (LTAA) of ITBB above 6.2 0 /0000, with the exception of Moscow and the Kaluga Region, where a further increase in the incidence of ITBB is possible. In 6 out of 16 regions with LTAA 2013–2022 between 3.31 and 6.2 0 /0000, an upward trend was observed, and in 8 – a decrease in morbidity. The trend towards an increase in morbidity was detected in 7 out of 21 entities with LTAA of ITBB from 1.21 to 3.3 0 /0000 and in 15 out of 26 regions with a low LTAA 2013–2022 (below 1.2 0 /0000). The analysis of trends in the development of the ITBB epidemic process against the trends in changes in the frequency of contacts of the population with ticks, as well as calculations of the probable incidence rate allowed us to conclude that the incidence rate of ITBB in 2023 will range within the confidence intervals of long-term average annual values for the majority of the federal districts, with the exception of the Central Federal District, where an increase in the number of cases of ixodic tick-borne borreliosis is likely to occur, provided that the existing volumes of preventive measures are maintained and abnormal climatic phenomena absent. Effective control of the epidemic situation on the ITBB is attainable through preservation, and for such areas as Moscow, the Moscow Region, Voronezh, Kaluga, Orel, Ryazan, Penza and Rostov Regions, the Republic of Buryatia – increase in the volume of preventive measures, strengthening zoological and entomological monitoring of activity and structure of natural foci. There is an obvious need to develop algorithms for molecular-genetic monitoring of pathogens circulating in natural foci, and to focus attention onto the problems of diagnosis and prophylaxis of tick-borne transmissible infections.

“…Altai Krai is endemic with tick-borne rickettsioses (TBRs) in the Russian Federation. This Asian region, as well as the adjacent areas of Russia (Novosibirsk and Kemerovo Regions, Altai Republic), and neighboring Kazakhstan are hotspots for tick-borne infections, particularly for TBR [ 1 ]. Several human pathogenic genospecies of the tick-borne spotted fever group rickettsioses (SFGRs) can be causative agents of TBR.…”

The prevalence of the tick-borne spotted fever group rickettsioses pathogens in ticks collected in Barnaul, the administrative center of Altai Krai, Western Siberia, was studied. The causative agent of tick-borne lymphadenopathy (TIBOLA) Rickettsia raoultii was revealed to be present in 61.9% of the samples from Dermacentor ticks. Moreover, Rickettsia helvetica has been identified in 5.1% of Ixodes ticks.

The south of Western Siberia traditionally belongs to the regions with an unfavorable epidemiological situation for infections transmitted by ticks. Approximately 20 thousand people annually seek medical care after a tick bite in Novosibirsk and its suburbs. The purpose of this work was to determine the species composition of ticks attacking humans in the territory of Novosibirsk and its suburbs by determining the nucleotide sequence of the fragment of the tick mitochondrial gene cytochrome oxidase COI during the spring-summer season of 2018, determination of infection of individual ticks with viral and bacterial tick-borne infections, followed by genotyping of identified pathogens by PCR methods, by determination of nucleotide sequences and phylogenetic analysis. It is established that ticks of five species attack the humans: Ixodes persulcatus, Ixodes pavlovskyi, Dermacentor reticulatus, Dermacentor marginatus, Dermacentor nuttali in the Novosibirsk metropolis. The majority of tick attacks on humans are associated with I. pavlovskyi (43.6%) and D. reticulatus (41.2%) ticks. The genetic material of the tick-borne encephalitis virus was detected in 3.6%, borrelia - 13.8% and rickettsia - 23.1% individual ticks collected from humans. Genotyping of the tick-borne encephalitis virus (TBEV) in the collected ticks showed the presence of the Siberian genotype of TBEV in 83% cases, and the Far Eastern genotype of TBEV in 17% of ticks. The Kemerovo virus could not be detected. Genetic material from Borrelia spp. and Rickettsia spp. has been detected in all five tick species attacking the local human population. The bulk of the identified Borrelia spp. isolates were genotyped as Borrelia garinii (86%) and 13% of the isolates as Borrelia afzelii species. The genetic material of Borrelia miyamotoi was found in one individual tick. Ticks of the genus Dermacentor have been found to infect by Rickettsia raoultii, and ticks of the genus Ixodes are overwhelmingly infected with Rickettsia tarasevichiae. Moreover, in single I. persulcatus tick was infected by Rickettsia helvetica. Thus, the human population of Novosibirsk and its suburbs is attacking by five species of ixodid ticks with the predominant dominance of I. pavlovskyi and D. reticulatus ticks. The genetic material of the following tick-borne infections was found: Siberian and Far Eastern genotype of TBEV, B. garinii, B. afzelii, B. miyamotoi, R. raoulti, R. tarasevichiae and R. helvetica in the individual ticks collected from humans.
