Salmonellosis in Poland in 2013

Journal Title: Przegląd Epidemiologiczny - Year 2015, Vol 69, Issue 4

Abstract

AIM. The purpose of the study was to evaluate the epidemiologic situation of salmonellosis in Poland in 2013 compared to previous years. MATERIALS AND METHODS. The main source of data for this study are statistical overviews included in annual bulletin “Infectious Diseases in Poland in 2013”, information from sanitary station laboratories as well as forms of outbreak investigations obtained from the sanitary stations. Information on deaths due to infectious and parasitic diseases registered in Poland in 2013 and earlier years is based on the data of the Department for Demographic Research of Central Statistical Office. For the purpose of surveillance cases were qualified according to the current definition. RESULTS. In Poland in 2013, a total of 7 578 cases of zoonotic salmonellosis were reported including 7 407 cases of intestinal salmonellosis and 171 of parenteral one. The incidence was 19,7/100 000. The criteria for a confirmed case were met by more than 96% of cases. The number of reported cases was lower than in previous year, reflecting the continued downward trend in the number of cases of salmonellosis in Poland. A very high percentage (more than 72%) of hospitalizations of people infected with zoonotic Salmonella continues. In the outbreaks the proportion of hospitalizations accounted only for 35% of all cases. Predominantly children below 5 years of age suffer from the illness. Salmonellosis was an indicated cause of death only in 10 of the cases. In 2013 179 outbreaks were reported, in which Salmonella was found to be the etiological agent. Majority of them were small household outbreaks and they cumulated for a total number of cases of 1 218. The most common species of Salmonella responsible for infection in Poland is S. Enteritidis. For many years, up to date a slight increase is observed in reported cases of the disease, but without known serotype of Salmonella. In 2013 it was 16% and (as in previous year) it was the highest in pomorskie voivodeship (58%). CONCLUSIONS. High percentage of hospitalizations for salmonellosis combined with the fact of rarely performed laboratory diagnostics of gastro- intestinal diseases indicates much underreporting of salmonellosis throughout the country. However decreasing number of cases registered yearly and also decreasing percentage of persons infected, involved in food processing leads to a conclusion of constant decreasing trend of salmonellosis prevalence.
