ABSTRACT

Ticks and tick-borne diseases represent a serious threat to public health. In Europe, the most important tick species is the common tick Ixodes ricinus. It transmits several human diseases including two most important: tick-borne encephalitis (TBE) and Lyme borreliosis (LB). The Czech Republic belongs to the countries with highest occurrence of both. Geographical distribution of these diseases is highly focal and therefore GIS technologies have a high potential of use in spatial epidemiology of tick-borne diseases. The main aim of our contribution is to introduce the possibilities of GIS utilization in the field of epidemiology using an example of the research project „Ticks and tick-borne diseases in South Bohemia and Bavaria“, realized 2009-2011. Various GIS tools and approaches were used in different phases of the project. Multi-criteria evaluation system was used for the design of study plots in field. Epidemiological data (numbers of disease cases) as well as data on tick and pathogen occurrence collected in field and laboratory were imported in the GIS database and visualized using GIS. In the last phase of the project mathematical risk models of tick and tick-borne pathogens distribution were constructed and subsequently visualized in GIS. The models are based on a thorough statistical analysis of various potential explanatory variables, including satellite images, climatic data etc. The main graphical outputs of the project were published in web-based map portal: http://gis.vsb.cz/klistata/.
