In accordance with the scenario of moderate anthropogenic impact on the Earth's climate system RCP4.5, by the middle of the 21st century, in general, the climatic ranges of vectors of many vector-borne human diseases and climatic spatial ranges of the diseases in Russia and neighboring countries will expand. This is expected, in particular, for the vectors of tick-borne encephalitis and ixodic tick-borne borreliosis, the Taiga tick I. persulcatus and the European tick I. ricinus. For the first one, the climatic range will slightly decrease in the western part (outside Russia) and expand in the north of the European part of Russia and the east of the Asian part of Russia. Climatic conditions for the establishment of the ticks’ populations will appear in the south of Western Siberia, the Far East and Kamchatka peninsula. This is also expected for the spatial ranges of some fevers, including West Nile fever and Crimean hemorrhagic fever. The climatic spatial range of West Nile fever will expand. No reductions are expected. The causative agent of this disease was found in a large number of vectors of the Russian fauna. Therefore, the absence of some of them will not be a limiting factor. Climatic spatial range of the Crimean hemorrhagic fever in Russia and neighboring countries will expand to the north, as well as to the highlands of the Caucasus and Central Asia. Reduction of the spatial range is also not expected. The consequences of expected expansion of the climatic ranges of vectors and climatic spatial ranges of human vector-borne diseases in general will be an increase in climate-related hazards to public health, which enhance the corresponding risks. To reduce the risks, it is expedient to include respective measures into the national adaptation plans, the development and implementation of which are prescribed by the Paris Agreement (2015). Such measures may include: - further development of monitoring of vectors of vector-borne human diseases and the morbidity; - reducing the exposure and vulnerability of people to emerging climate-related hazards; - strengthening sanitary and epidemiological control in this sphere; stimulation of relevant scientific developments. An effective solution to these tasks requires close cooperation between health authorities and national hydrometeorological services.
