title: Clinical and epidemiological characteristics of novel AHIN1 flu.
abstract: BACKGROUND
  Swine influenza is respiratory infection caused by virus influenza A H1N1.
  
  
  OBJECTIVE
  To show epidemiological and clinical characteristic of patients with confirmed influenza A H1N1 hospitalized at Clinic for Infectious Diseases of University Clinical Center Sarajevo.
  
  
  METHODS
  We analyzed 127 medical records of patients with microbiologically confirmed pandemic influenza A/H1N1 (nasopharyngeal swab analyzed by PCR method).
  
  
  RESULTS
  In our investigation female patients prevail (57%), age from 25 to 45 years old with medium difficult clinical picture (71.55%). Chi-square test showed significant dependence between sex and clinical status of patient (p < 0.05), dyspnea and clinical status of patient (p < 0.05), while statistical significance was nor proved related to comorbidity (p > 0.05), cough (p > 0.05), radiological confirmed pneumonia (p > 0.05), number of prehospital days of diseases (p > 0.05) and length of hospital care (p > 0.05). Significant impact on clinical status of patients is found related to age (p < 0.05), in a way that every year of age increase risk in 2.9% for more severe disease.
  
  
  CONCLUSIONS
  Clinical and epidemiological parameters can impute severity of clinical status and therefore the outcome of disease.
