    Abstract:
    THE PURPOSE OF THE STUDY: To assess the epidemiological situation of salmonellosis in Poland in 2011 as compared with previous years. MATERIALS AND METHODS: The assessment was based on the results of analysis of the data from the newsletter "Infectious diseases and poisonings in Poland 2011", information from laboratories of sanitary-epidemiological stations and reports of epidemiological investigations performed in outbreaks of salmonellosis, sent by the sanitary-epidemiological stations to the Department of Epidemiology and also on the data from the Department for Demographic Research, Central Statistical Office. For the purpose of surveillance disease were classified in accordance with the current case definition. RESULTS: In 2011, the total number of cases of zoonotic salmonellosis registered in Poland was 8 813. Out of it 8 652 cases were of intestinal salmonellosis and 161 of parenteral. The overall incidence was 22.9/100 000. Over 95% of cases met criteria of confirmed case. The number of registered cases was the lowest ever recorded, indicating a continuing downward trend in incidence of salmonellosis in Poland. Maintains a high percentage of hospitalization, almost 70% of people infected with zoonotic Salmonella - but in outbreaks the figure is more than two and a half times lower and is less than 27%. The incidence was highest among children less then five years old. No deaths were registered with the salmonellosis indicated as the underlying cause. In 2011 there were reported 174 outbreaks caused by Salmonella, in which 1774 people fell ill. They were mostly small family outbreaks. Still the most common etiologic factor in Poland is S. Enteritidis. In 2011, fraction of Salmonella rods without confirmed species increased by 13% compared to 2010. In the province of Pomorskie it was the highest and reached 45%. CONCLUSION: A very high percentage of hospitalized cases of salmonellosis that persists for many years at 70%, testifies to the recognition and reporting mostly the more severe cases. This means that reporting ofsalmonellosis in Poland is largely under-diagnosed and underreported. The fact that increasing the percentage of Salmonella that are not serotyped is another problem of concern.
