    Abstract:
    AIM: The aim of this study is to present the epidemiology of salmonellosis in Poland in 2010. MATERIAL AND METHODS: The study was based on data from: "the Infectious diseases and poisonings in Poland 2010", information from laboratories based in sanitary stations, the forms of outbreaks investigations conducted by sanitary stations and data from Demographic Surveys Departament based in the Central Statistical Office. All cases were classified according to the case definition used by surveillance. RESULTS: A total of9 732 salmonellosis cases were reported in Poland. Among them 8 549 cases were intestinal and 183 were extraintestinal. The incidence rate was 25.5 per 100 000 inhabitants. Over 95% of cases met the criteria for a confirmed case. The number of registered cases was higher than in the previous two years, despite this an overall decreasing trend was observed in the number of cases of salmonellosis in Poland. Cases of salmonellosis occurred primarily among children under 5-years old. There were no deaths reported due to salmonellosis. There is still a high percentage, about 70%, hospital admissions of people infected with zoonotic Salmonella. The percentage of hospitalization in outbreaks is almost two and a half times lower -29%. In 2010, 189 outbreaks caused by Salmonella were reported, affecting 1 662 people (almost 18% of all reported cases of intestinal salmonellosis). Most were small family outbreaks. Still the most common etiologic agent in Poland is S. Enteritidis. When compared with previous years, in 2010 there was an increase in the number of cases caused by S. Mbandaka, S. Infantis and S. Virchow. The number of screening tests for carriers among food handlers decreased by over 10% however the percentage diagnosed with positive result increased from 0.3% to 0.5%. CONCLUSIONS: Human salmonellosis is still a significant public health problem in Poland. The very high percentage (70%) of hospitalization, persisting for many years indicates that diagnosis and reporting ofsalmonellosis in Poland is mainly among severe cases. This allows to conclude that the incidence of salmonellosis in Poland is largely under-diagnosis and under-reported.
