title: [Analysis of 96 cases with novel H1N1 influenza A].
abstract: OBJECTIVE
  To review the epidemiologic and clinical characteristics of 96 cases with novel H1N1 influenza A, and improve the diagnosis and treatment level of novel H1N1 influenza A.
  
  
  METHODS
  96 cases of novel H1N1 influenza A admitted to the isolation wards from Oct 20 to Sep 23, 2009 were studied. Their epidemiologic, clinical, laboratory, and radiologic characteristics were analyzed.
  
  
  RESULTS
  The median age of the 96 patients was 26.52 +/- 10.62 years (range, 5 to 60 years). Sixty-four of the 96 patients had a close contact with novel H1N1 influenza A patients. The main symptoms included fever 100%, cough 86.4% , sore throat 66.6% and myalgia 32.3%.
  
  
  CONCLUSIONS
  The clinical presentation of novel H1N1 infection is largely indistinguishable from that of seasonal influenza. Combines both a symptom complex with the epidemiological investigation and laboratory characteristics can improve the accuracy of diagnosis of novel H1N1 influenza A.
