title: Salmonellosis in Poland in 2014
abstract: The aim of the study is to assess the epidemiological situation of salmonellosis in Poland in 2014 in comparison to the previous years.
  
  
  
  The evaluation was based on the data from the bulletin “Infectious diseases and poisoning in Poland 2014”, information from the laboratories of sanitary-epidemiological stations and reports from the epidemiological investigations in outbreaks of salmonellosis, sent by the sanitary-epidemiological stations to the Department of Epidemiology, as well as the data from the Department of Demographic Studies of the Central Statistical Office. Cases were classified according to the definitions adopted in the UE.
  
  
  
  In 2014, a total number of 8 392 cases of salmonellosis derived from animals were reported, including 8 197 cases of intestinal salmonellosis and 195 cases of extraintestinal. The total incidence was 21.8/100 000. Almost 96% of the cases met the criteria for a confirmed case. The number of registered cases was, for the first time since many years, higher than in the previous year, but still lower than the median for 2008-2012. A very high percentage (approximately 70%) of hospitalizations remains among patients diagnosed with salmonellosis. Approximately 33% of all cases in outbreaks of salmonellosis were hospitalized. The highest incidence was among children under the age of 5 years. Salmonellosis was reported as the cause of death for 13 patients. In 2014 there were 171 outbreaks reported with Salmonella as an etiological agent. Majority of them were small outbreaks limited to the family in singular household, and the total number of cases in those outbreaks amounted to 1 229 people. In Poland the most common etiological agent of salmonellosis is (and have been for many years) S. Enteritidis.
  
  
  
  In 2014, the first time in many years, an increase was recorded in the annual number of cases of salmonellosis. A very high percentage of hospitalizations for salmonellosis cases indicates a relatively rare practice among GPs in ordering laboratory testing in patients presenting with gastroenteritis. This causes significant underreporting of salmonellosis in throughout the country and indicates the need to introduce mechanisms which would make laboratory testing for salmonellosis as a recommended practice.
