[Objective] To analyze the epidemic characteristics of influenza-like cases and provide the basis for influenza prevention and control measures. [Method] The monitoring data of sentinelly sentinel hospital in Zhangqiu City from October 2005 to December 2009 and the etiological detection data from August to December in 2009 were analyzed. [Results] From October 2005 to December 2009, 6 370 cases of influenza-like illness were reported in the outpatient departments of sentinel hospitals, accounting for 3.43% of the 185 479 cases of outpatient visits in the same period. The proportion of flu-like cases was 2.32%, 2.87%, 3.82%, 2.93% respectively in the four monitoring years from October 2005 to March 2009, 3.74% in May-December 2009 and 5.07 in pediatric outpatients %, Pediatric emergency department was 6.43%, medical clinic was 0.17%, medical emergency (including fever clinic) was 8.11%; from October to next March were 2.37%, 2.81%, 3.27%, 3.98%, 3.50%, 2.70 % From May to December 2009 were 2.73%, 3.14%, 2.57%, 1.18%, 5.61%, 6.66% 7, .41% and 5.29% respectively. Eighty-eight swabs of influenza-like patients were collected from August to December in 2009, and 78 influenza viruses were detected, the positive rate was 34.21%, including 50 strains of H3 virus of seasonal influenza virus, 1 strain of H1, 1 of type A 2 strains of type B, 19 strains of type A H1N1. [Conclusion] The proportion of flu-like cases among the total number of outpatients in the outpatient department of influenza epidemic seasons in sentinel hospitals from 2005 to 2009 in Zhangqiu City was relatively stable. The seasonal flu virus H3 and H1N1 influenza viruses from August to December 2009 were Advantageous strains.
