Actual Problems of Epidemiological Surveillance of West Nile fever in Russia and Ways of Its Improvement

Relevance. The relevance of this work is determined by obtaining new data on the geography of distribution and manifestations of the epidemic process of West Nile fever in Russia as a result of exploratory scientific research and systematization of the results of long-term (since 2010) monitoring of the causative agent of this infection. Aims: assessment of the state and effectiveness of epidemiological surveillance of WNV and optimization of its methodological, scientific and practical support. Materials & Methods . We used the reporting data of the Rospotrebnadzor Directorates for the constituent entities of the Russian Federation, received by the Reference Center for monitoring the causative agent of West Nile fever, materials from scientific publications, monographic publications and dissertation research. The main research method is epidemiological. Results and discussion. The problems of monitoring the causative agent of West Nile fever are identified, which make it difficult to obtain objective data on the manifestations of epidemic and epizootic processes, the frequency of contacts of the population with the causative agent of the disease, and the possibility of developing epidemiological forecasts. The key areas for improving the monitoring system for the causative agent of West Nile fever are considered: conducting active reconnaissance surveys aimed at clarifying the nosoarea, performing an assessment zoning of the territory of Russia, establishing minimum volumes of epizootological monitoring, ensuring the readiness of medical organizations to identify and diagnose cases of diseases, strengthening organizational and control functions Directorates of Rospotrebnadzor for the constituent entities of the Russian Federation, the frequency of studies in administrative territories to study the immune layer of the population to the West Nile virus and the differentiation of the immune response to the tick-borne encephalitis virus. Conclusions. The proposed set of measures will improve the objectivity and reliability of information received within the framework of the functioning of the epidemiological surveillance system, timely adjust preventive measures and take maximum control over the development of the epidemiological situation in the territory.
