ABSTRACT
INTRODUCTION: Bacteria Legionella sp. found in water distribution systems, especially warm, transferred to water spray devices for aerators and showers in the form of aerosols infected with them become a threat to the human inhaler. OBJECTIVE: Assessment of colonization of the water supply network with Legionella bacteria in teaching and education facilities in Malopolska in 2016 year. MATERIAL AND METHODS: The results of water samples taken from plumbing installations were analyzed in teaching and education facilities by employees of the State Sanitary Inspection of the Lesser Poland Voivodeship. RESULTS: The results of 366 testing hot water samples in 111 teaching and education centers in Malopolska have shown that in 123 testing samples (33,6%) in 48 centers (43,2%) the water sample was colonized with Legionella sp. and the water quality did not meet the requirements of the current ordinance of the Minister of Health. CONCLUSIONS: It is justified to periodically monitor the presence of Legionella sp. in water supply installations in teaching and education centers and taking action to reduce the colonization of these bacteria.

OBJECTIVE: Lyme disease is one of the most known tick borne diseases in Poland caused by spirochetes of the genus Borrelia burgdorferi. Most cases of Lyme disease are diagnosed in the northeastern Poland and the south of Poland, in Slaskie, Malopolskie, Podkarpackie voivodeship. The aim of the study was to evaluate epidemiological data of Lyme disease in Malopolskie voivodeship and other voivodeships in Poland and frequency analysis of the Lyme disease as an occupational disease. METHODS: The authors analyzed prevalence from 1998 to 2014. Incidence of the Lyme disease was evaluated through review data from "Choroby zakazne i zatrucia" Bulletin and Lyme disease as an occupational disease obtained data from the Nofer Institute of Occupational Medicine in Lódz. RESULTS: It is estimated that the number of Lyme disease cases in Poland increased 18 times between 1998 and 2014 year (2,0 to 36 per 100,000 population), in the same period it was over 35 times of sudden rise in Lyme disease incidence in Malopolskie voivodeship. In years 2005-2014 the number of cases of Lyme disease as an occupational disease fluctuated with a slight upward trend both in Poland and Malopolskie voivoideship. CONCLUSIONs: In Poland number of reported cases is systematically increasing. Podlaskie and Warminsko- Mazurskie voivodeships are areas of high prevalence. Exponential increase in the number of cases is observed in southern Poland, especially in Malopolskie voivodeship from 2013.
