Abstract：Objective This paper aimed to provide scientific basis for influenza prevention and control measures by analyzing the etiological and epidemic characteristics of influenza in Jilin Province during 2012-2014. Methods Real-time PCR assay was used for the detection of influenza virus nucleic acid in the nasopharyngeal swab specimens collected from influenza patients in the sentinel hospitals of Jilin Province during 2012-2014. The positive rate of influenza virus and epidemic strains of flu were analyzed. Results Among the 21,532 nasopharyngeal swab specimens from influenza-like cases, 2,420 were detected to be positive for influenza virus, with the detection rate of 11.24%. The type of epidemic strains of flu were changing in recent years.The main epidemic strains of flu in 2012 and 2014 were H3N2, accounting for 64.78% and 86.40% respectively, while the main epidemic strain in 2013 was H1N1 (60.27%), and a new type, H7N9(0.22%), appeared in 2013. The positive rate of influenza virus in the specimens from the influenza patients was associated with year, region and age, but not related to gender. The positive rate was the lowest (10.13%) in 2013 and highest (12.13%) in 2014, lowest (2.95%) in Liaoyuan City and highest (16.24%) in Baishan City, as well as lowest (9.29%) in the 0~ year group and highest (14.04%) in the 5~ years group. Conclusions The positive rates of influenza virus in influenza patients in Jilin Province in 2012-2014 are different among years, regions, and age groups. And the type of epidemic strain varies among years. It’s necessary to monitor the epedimic trend of influenza over a long period to timely discover the variants and provide evidence for formulating influenza prevention measures.
