Background: Tick-borne diseases are a serious threat to the epidemiological safety of the population of the Stavropol Region, making up more than 70 per cent of all natural focal infectious diseases registered in this territory annually. A wide range of hosts contributes to high tick abundance, diversity of tick-borne pathogens, and maintenance of the natural foci. Objective: To assess the activity of natural foci of tick-borne infections in the Stavropol Region in 2016–2020. Materials and methods: We used notifications submitted by the Center for Hygiene and Epidemiology in the Stavropol Region to the Scientific and Methodological Center for Monitoring the Pathogens of Infectious and Parasitic Diseases of Pathogenicity Groups II–IV for the subjects of the North Caucasian and Southern Federal Districts and the results of an epizootological survey of the Stavropol territory by specialists of the Stavropol Plague Control Research Institute. Markers of the causative agents of tick-borne diseases were detected by ELISA and PCR methods. Data processing was carried out using Microsoft Excel 2010. Results: Active natural foci of Crimean-Congo hemorrhagic fever, Q fever, a group of tick-borne spotted fevers, Lyme disease, human granulocytic anaplasmosis, and human monocytic ehrlichiosis were established in the region in 2016–2020. Human cases of the Crimean-Congo hemorrhagic fever, Lyme borreliosis and Q fever were also registered annually. The abundance of infected ticks in resort towns of the Caucasian Mineral Waters is of particular concern. Conclusion: We established up-to-date epizootic and epidemic manifestations of tick-borne infections in the Stavropol Region in the modern period, which are an important link in epidemiological surveillance and the basis for improving preventive measures

Epidemiological Situation

Represented is the analysis of epidemiological situation on vector-borne natural-focal infections in the specially protected eco-resort territory of Russia - Caucasian Mineral Waters of the Stavropol Region. Climactic peculiarities of Caucasian Mineral Waters with their landscape diversity, high abundance rates of ticks and mosquitoes, and anthropogenic impact on ecosystems create favorable conditions for natural foci formation. Crucial epidemiological significance in the regional infectious pathology is attributed to tick-borne borreliosis. Registration of Crimean hemorrhagic fever cases, as well as West Nile (retrospectively) fever and tularemia cases, and identification of specific antibodies to etiological agents of these infections in blood sera of donors testify to volatile epidemiological situation on vector-borne natural-focal infections in the region, which means that there is a need for further ecological, epidemiological and epizootiological monitoring as a constituent element of epidemiological surveillance aimed at provision of sanitary-epidemiological welfare of the population.

Review Study

Vector-borne diseases have become a global health concern in recent decades as a result of global warming, globalization, growth in international trade and travel, use of insecticide and drug resistance. This review study addressed the key vector-borne diseases and their current status in Iran to emphasize the requirements for further research on vector-borne diseases. The dispersion patterns of these diseases differ in various regions. Some of them such as Crimean–Congo hemorrhagic fever, and Q fever are distributed all across Iran, whereas some others such as plague, leishmaniasis, tularemia, and malaria are restricted to specific areas. The high prevalence of vectors throughout the country necessitates enhancing the monitoring and surveillance of emerging and reemerging vector-borne diseases and their potential vectors.

Aim. Analysis of epidemic manifestations of natural-foci infections (NFI), clarification of spectrum of their causative agents, determination of epizootic activity of natural foci in the Crimea Federal District (KFD). Materials and methods. Epizootologic examination of 10 administrative districts of KDF was carried out. 291 pools (2705 specimens) of ixodes ticks and 283 samples of organs of small mammals were studied by PCR method for the presence of DNA/RNA of causative agents of a number of NFI. Results. Morbidity by NFI in KFD was registered by 6 nosologies: Lyme borreliosis, Marseilles fever, leptospirosis, tularemia, intestine yersiniosis and tick-borne viral encephalitis, wherein, transmissive infections made up 91.6%. Circulation of causative agents of Crimea hemorrhagic fever, Q fever, group of tick-borne spotted fever, Lyme borreliosis, human granulocytic anaplasmosis, human monocytic ehrlichiosis, hemorrhagic fever with renal syndrome, West Nile fever, tularemia and leptospirosis was established. Conclusion. Due to activity of natural foci of NFI further monitoring of epidemiologic and epizootologic manifestations of these infections in the Crimea, including using genetic methods of analysis, is necessary for ensuring sanitary-epidemiologic welfare of KFD population.

In Kazakhstan natural foci of Crimea-Congo hemorrhagic fever is located on the territory of Turkestan, Kyzylorda and Zhambyl regions. Whereas preventive measures are taken, this disease is diagnosed annually among people, but there is a group of viruses such as Karshi, Tamdy, the Issyk-Kul fever virus and Syr Darya valley fever which are less known. In this regard the goal was set to identify the prevalence of viruses of Karshi, Tamdy, Issyk-Kul fever and fever of the Syr Darya valley in hemorrhagic fever endemic in the Crimea-Congo hemorrhagic fever to determine the main hosts and vectors of infection. Ticks captured in areas natural foci of the Crimean-Congo hemorrhagic fever virus. The species composition of captured ticks was represented by 9 species: Hyalomma scupense, Hyalomma asiaticum, Hyalomma turanicum, Hyalomma anatolicum, Haemaphysalis sucata, Haemaphysalis punctata, Dermacentor niveus, Rhipicephalus pumilio, Rhipicephalus schulzei. Preliminary work was carried out on the selection and design of oligonucleotide primers for the identification of viruses by molecular genetic analysis. As a result of the studies, positive samples were found for viruses of Tamdy and Syr Darya valley fever in ticks H. asiaticum, H. scupense from the Turkestan region. The Crimean-Congo hemorrhagic fever virus was detected in H. asiaticum and H. scupense ticks from Zhambyl and Turkestan regions.

Investigation of the fauna of Ixodidae ticks in the territory of the Rostov Region resulted in identification of the seven species belonging to five genera – Hyalomma, Dermacentor, Rhipicephalus, Ixodes, Haemaphysalis: H. m. marginatum, H. scupense, D. marginatus, R. rossicus, I. ricinus, I. laguri and Haem. punctata. Continuous expansion of H. m. marginatum to the northern part of the region was observed. Analysis of spatial distribution of H. m. marginatum as well as D. marginatus, R. rossicus, I. ricinusand other ticks using average indices of their long-term abundance permitted to identify groups of areas with low, increased and high indices of tick abundance. This allowed to determine potential risk areas, with the presence of vectors and a reservoir of tick-borne infections as Crimean hemorrhagic fever, Q fever and tick-borne borrelioses. The results obtained in the investigation could serve as a basis for carrying out epizootic surveys and implementation of specified preventive measures.
