ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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%.</p><p><b>CONCLUSION</b>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.</p>
