title: [Yersiniosis in Poland in 2010].
abstract: METHODS
  The study was based on data from: the "Infectious diseases and poisonings in Poland" bulletins published annually between 2005-2010 (MP Czarkowski i in., PZH i GIS), individual case interviews conducted by sanitary stations and data from Demographic Surveys Departament based in the Central Statistical Office. Analysis of the incidence of yersiniosis in the country during 2010 was based on data on clinical symptoms associated with the disease, age groups, the number of cases in different provinces and the serotypes of Yersinia which were isolated.
  
  
  RESULTS
  A total of 233 yersiniosis cases were reported in 2010 in Poland. The incidence rate was 0.61 per 100 000 inhabitants. In this year 206 cases of intestinal yersiniosis and 27 cases of extraintestinal yersiniosis were notified. No yersiniosis related deaths were reported. Approximately 76% of patients were hospitalized. The most common clinical symptoms of intestinal yersiniosis cases were: diarrhea (82%), high temperature (72%), abdominal pain (39%) and vomiting (34%). The most common symptom of the extraintestinal form of yersiniosis was discomfort to part of the osteoarticular system, which occurred in 59% of patients. The highest incidence rate of intestinal yersiniosis was among children in 0-4 years old. The largest number of yersiniosis cases were reported in Mazowieckie voivodeship, while the least number of cases were reported in Podlaskie and Swietokrzyskie voivodeships. In 2010 only one outbreak of yersiniosis was reported. Three serological types of Yersinia enterocolitica were isolated: 03 (71.2%), 08 (26.3%) and 09 (2.5%).
  
  
  OBJECTIVE
  The aim of this study is to present the epidemiology of intestinal and extraintestinal yersiniosis in Poland in 2010.
  
  
  CONCLUSIONS
  A very large percentage (65.6%) of isolated strains of Yersinia were not serotyped. Yersinia serotype 08 remains very common serotype reported, despite a decline in 2010 in the number of cases notified. The high percentage of hospitalization points that patients with gastrointestinal symptoms are relatively rare direct to routine laboratory diagnostic of Yersinia infection.
