Edyta Zawłocka¹, *Teresa Jackowska^{1, 2}

Summary
Introduction. In Poland, depending on the epidemiological period, from a few thousand to several million cases and/or suspected cases of flu and/or flu-like infections are recorded.
Aim. The paper presents an analysis of the flu infections in a pediatric ward in Warsaw, in one influenza season. The analysis concerned the hospitalization and the costs of hospitalization due to influenza. The degree of the implementation of immunization was assessed both in the patients as well as the family before and after the hospitalization due to influenza.
Material and methods. At the Hospital Emergency Department (HED) and the Department of Paediatrics (DP) Bielański Hospital in Warsaw, 65 patients (aged 0-18 years) diagnosed with influenza A and/or B were hospitalized in the 2012/2013 season. The suspicion of flu was based on the history, physical examination and laboratory tests, and, the diagnosis was based on the result of the rapid diagnostic test (Rapid Influenza Diagnostic Test – RIDT) and/or the result of the molecular biology test (Real-Time-Polymerase Chain Reaction – RT-PCR).
Results. In 35.4% (23/65) of patients influenza A was diagnosed, and in 60% (39/65) influenza B. Three (4.6%) children had influenza A and B. 70.8% (46/65) of the patients required hospitalization in DP, and the average hospital stay was 7.5 days. 90.8% (59/65) of the children were treated with oseltamivir for 5 days. In 36.9% (24/65) of them various complications were observed that required further treatment. The cost of hospitalization ranged from PLN 1761 to PLN 2057 for stays without uncomplications and from PLN 2607 to PLN 4595 for stays with complications. None of the examined children had been vaccinated against influenza before the influenza season, and only two were vaccinated in the following season.
Conclusions. Influenza is a disease that may have a severe course and patients may require hospitalization. The possible complications of the flu prolong the time of the treatment and result in additional costs. There are effective medicines against the flu available, but the best form of preventing influenza are annual vaccinations. In the group studied, in spite of the severe influenza course, requiring hospitalization, the parents’ attitudes to vaccinations have not changed and remained negative.
