[Salmonellosis in Poland in 2003].

Total number of salmonellosis cases sharply decreased. In 2003, 16 617 cases were reported (20 688 in previous year), incidence rate = 43.5 per 100 000 population. 72.7% of patients were hospitalized, but percentage of hospitalized cases with extraintestinal manifestations was much higher--above 90%. The seasonal peak was observed as in previous years in July and August. The most frequent isolated type remained Salmonella Enteritidis--above 85% of cases. Only three other serotypes (Hadar, Typhimurium and Infantis) were detected in all of 16 voivodeships of Poland. The age, sex, urban/rural distribution of salmonellosis cases remains stable; the highest incidence was registered among children aged 2 (425.5/100 000). Extraintestinal manifestations of salmonellosis (septicemia, meningitis, pneumonia peritonitis and other) were observed in 121 patients (the highest number since 1994).
