[Salmonellosis in Poland in 2005].

In 2005, 16,006 salmonellosis cases were reported (15,958 in previous year), the incidence rate was 41.9 per 100,000 population. Seventy percent of patients were hospitalized, however the hospitalization ratio was higher for extraintestinal manifestations--91%. As in previous years the seasonal peak was observed between June and August. The most frequently isolated type remained Salmonella Enteritidis--above 84% of cases. Only four other serotypes (Typhimurium, Infantis, Hadar and Virchow) were detected in Poland. The age, gender, and urban/rural distributions of salmonellosis cases are similar to previous years. Children aged 2 are the mostly affected age group (incidence 444.8 per 100,000 population). Extraintestinal manifestations of salmonellosis were observed in 191 patients (the highest number since 1994).
