Article Synopsis
- There has been a significant rise in tick bites among people in northern European Russia, coinciding with notable climate changes, like increased air temperatures.
- The study uses official statistics on human tick bites to analyze the impact of climate change on tick populations, which is challenging to study in the field due to the large area involved.
- An S-shaped relationship between the number of tick-bite victims and average annual air temperature, described by "Verhulst's law" (logistic function), indicates that tick population dynamics are influenced by temperature rather than time.
Background: The causes of the recent rise of tick-borne encephalitis (TBE) incidence in Europe are discussed. Our objective was to estimate the impact of air temperature change on TBE incidence in the European part of the Russian Arctic.
Methods: We analysed the TBE incidence in the Komi Republic (RK) over a 42-year period in relation to changes in local annual average air temperature, air temperature during the season of tick activity, tick abundance, TBE-prevalence in ticks, tick-bite incidence rate, and normalised difference vegetation index within the area under study.
