title: [A(H1N1)v cases of the 2009/2010 and 2010/2011 influenza seasons in the Medical and Health Sciences Centre of Debrecen University].
abstract: The swine-origin new influenza variant A(H1N1) emerged in 2009 and changed the epidemiology of the 2009/2010 influenza season globally and at national level.
  
  
  OBJECTIVE
  The aim of the authors was to analyse the cases of two influenza seasons.
  
  
  METHODS
  The Medical and Health Sciences Centre of Debrecen University has 1690 beds with 85 000 patients admitted per year. The diagnosis of influenza was conducted using real-time polymerase chain reaction in the microbiological laboratories of the University and the National Epidemiological Centre, according to the recommendation of the World Health Organization.
  
  
  RESULTS
  The incidence of influenza was not higher than that observed in the previous season, but two high-risk patient groups were identified: pregnant women and patients with immunodeficiency (oncohematological and organ transplant patients). The influenza vaccine, which is free for high-risk groups and health care workers in Hungary, appeared to be effective for prevention, because in the 2010/2011 influenza season none of the 58 patients who were administered the vaccination developed influenza.
  
  
  CONCLUSIONS
  It is an important task to protect oncohematological and organ transplant patients.
