Borreliosis in Humans in the Region of Warmia and Mazury in 1999-2008
The objective of this study was to analyze the prevalence of borreliosis in humans over a period of ten years (1998-2008) in the Region of Warmia and Mazury, and to compare the results of the analysis with data for all Poland, provided by the National Institute of Hygiene. The incidence statistics for human borreliosis in the Region of Warmia and Mazury between 1999 and 2008 were developed based on the data supplied by the Regional Sanitary and Epidemiological Station in Olsztyn. In Warmia and Mazury, as in other parts of Poland, an increase in the incidence and prevalence of human borreliosis has been noted. In the analyzed decade, the number of borreliosis cases increased from 111 in 1999 to 609 in 2008. The steepest increase in the incidence rate of borreliosis was observed in 2006, while the highest number of cases (699) was reported in 2007. Districts that were most affected by the disease were Olsztyn and Ostróda, while the lowest number of cases was noted in Węgorzewo and Braniewo. The highest incidence rates for borreliosis were reported in the districts of Ełk and Ostróda. In Warmia and Mazury, women were more susceptible to the disease than men, and the highest number of patients were aged from 50 to 59. The results of the analysis indicate that borreliosis is increasingly diagnosed in patients who do not show symptoms of the disease in the form of the erythema migrans (EM) rash.
