title: Campylobacteriosis in Poland in 2011.
abstract: OBJECTIVE
  To assess the epidemiological situation of campylobacteriosis in Poland in 2011 as compared with the situation in 2010.
  
  
  METHODS
  The assessment was based on the results of the analysis of data from the annual bulletin "Infectious diseases and poisonings in Poland", 2010-2011 (MP Czarkowski et al., NIH and GIS), information from the forms of individual cases and epidemiological investigations forms on outbreaks of campylobacteriosis, which were sent by the Sanitary-Epidemiological Stations to the Department of Epidemiology and data from the Department of Demographic Studies of the Central Statistical Office. All cases were classified according to a surveillance case definition.
  
  
  RESULTS
  In 2011, number of campylobacteriosis cases registered in Poland was 354, the incidence rate was 0.92/100,000. All cases were reported as confirmed. No deaths were recorded. More than 61% of reported cases came from two provinces--Slaskie 112 (31%) and Warmińsko-mazurskie 104 (29%). The highest incidence was observed in Warmińsko-Mazurskie (7.16/100,000). Hospitalized were 57.5%. The lowest percentage of hospitalization (31.3%) was in Slaskie. In six provinces all reported cases were hospitalized. Campylobacter species was determinated in 282 patients (79.7%). It was found that 270 cases were caused by C. jejuni and 12 by C. coli. The majority of cases (264, 74.6%) occurred in the age group 0 - 4, Among the cases were 217 men and 127 women. In 2011, one family outbreak was caused by Campylobacter.
  
  
  CONCLUSIONS
  In Poland, campylobacteriosis is rarely diagnosed and recorded. Routine diagnosis of infection with Campylobacter is done in two provinces only.
