Results of Field and Laboratory Studies of Carriers and Vectors of Natural-Focal Infections on the Territory of the Republic of Armenia

Abstract

The purpose of the study was to assess the current epizootic potential of the Transcaucasian high-mountain and Pre-Araks low-mountain natural plague foci on the territory of the Republic of Armenia using GIS technologies. Materials and methods. We used the data from an epizootiological survey, records of the abundance and species composition, spatial distribution of rodents and ectoparasites in the plague-enzootic territories of the Republic of Armenia in 2021. Results and discussion. Based on the results of the research, an electronic database of carriers and vectors of pathogens of natural-focal zoonotic infections in the plague-enzootic territories of the Republic of Armenia has been created. Applying GIS technologies, an assessment of the spatial distribution of carriers and vectors of plague has been made and areas of circulation of tularemia and leptospirosis pathogens identified. The results obtained serve as the basis for improving the efficiency of planning and carrying out preventive measures aimed at ensuring the epidemiological welfare as regards natural-focal infectious diseases in the territory of the Republic of Armenia.
