| description | Introduction: Tick-borne infections (TBI) require special attention of health-care specialists due to their high epidemic significance. Russia is a country with high addressing of population for medical aid due to tick bites. Incidence rate of tick-borne infections change dramatically across different regions of the country. Aim: analyze several features of epidemiological manifestations of tick-borne infections in the Amur region. Materials and methods: Analysis of registered TBI incidence among the Amur Region population was based on official statistics data during 2014-2023 years. Analysis of nosological forms structure, age and gender groups of infected with TBI as well ad distribution of TBI cases was carried out. Annual indices of people seeking medical care due to tick bites and frequency of pathogen detection of engorged ticks were calculated. Results: Currently, only three TBIs are officially registered in the Amur Region: tick-borne encephalitis (TBE), tick-borne rickettsiosis (TBR) and Lyme disease (LD). Epidemiological analysis allowed to establish a downward trend of TBI incidence from 4,810/0000 in 2014 to 0,260/0000 in 2021, prevalence of tick-borne rickettsiosis (56,77%; 95% CI: 48,98-64,57%) in the structure of long-term incidence of the region population. The highest registration of cases were registered in steppe landscape zones (57,42%; 95% CI: 48,38-66,46%). The proportion of adult patients with TBI (18 years and older) accounted for 85.81% (95% CI: 80.32-91.30%), and the proportion of children (under 17 years) – 14.19% (95% CI: 8.70-19.68%), p<0.001. It is noteworthy that among the adult population of the Amur region there were more urban residents in the region with TBI than rural ones: respectively, 60.15% (95%CI: 51.82-68.48%) and 39.85% (95%CI: 31.52-48.18%), p<0.001. Among children with TBI, on the contrary, rural residents prevailed – 19 out of 22 children or 86.36 Statistically significant relationship between people seeking medical care due to tick bites and TBI general incidence (r=0,64), LD incidence (r=0,82), as well as correlation between LD incidence and frequency of detection of borrelia in ticks taken from population (r=0,677) were observed. Discussion: In the Amur region, in contrast to the all-Russian data, a feature in the age distribution of the incidence of TBI was revealed, which consisted in the dominance of the adult population. In the age cohort of 18 years and older, urban residents prevailed among patients with TBI under the inhabitants of rural areas. The adult population of the Amur region is infected with TBI pathogens in the course of their professional and household activities in natural foci of infections and during the rest of the townspeople in summer houses, which is typical for whole Russia. Conclusion: Further development of the epidemiological situation in the Amur region regarding TBI will be defined by changes of forest cover area determined by anthropogenic transformation and natural emergencies. |
