[Ecologic study of the risk of tick-borne encephalitis in Poland--presentation of the method].
Currently an ecologic study assessing the relationship between tick-borne encephalitis (TBE) with diverse environmental and social factors at the lowest administrative level is developed for Poland. Because the disease is affecting only part of the country, the authors will try to identify factors which could explain this uneven geographic distribution of the disease. To increase precision of the analysis we will utilize the highest possible resolution of the analysis, for which routinely collected data are available. Part of the data at the commune level will be obtained from the Polish communicable disease surveillance system and the Central Statistical Office, and part will be obtained using GIS tools from maps prepared by diverse institutions. The outcome studied will be TBE cases assigned to commune of residence or to place of exposure. The explanatory variables will be: land use categories (percent of commune area and their border length), meteorological variables (temperatures, rainfall), socio-economic status of communes (income per capita, unemployment rate), and Lyme borreliosis incidence (as a complex indicator of tick activity and human to tick exposure).
