Objective To analyze the prevalence of influenza in Daxing District of Beijing and provide a scientific basis for formulating prevention measures and measures. Methods Descriptive epidemiological methods were used to analyze the data of influenza and human bird flu surveillance in Daxing District from 2013 to 2014. Results From September 30, 2013 to April 6, 2014, a total of 7 549 flu-like cases (ILIs) were reported in Daxing District, accounting for 0.57% of the total number of outpatient and emergency department cases. ILI mainly concentrated in the 25 to 59 age group, accounting for 49.01% of the total. 540 samples of ILI throat swab were collected, and 61 samples were positive, the positive rate was 11.30%. Among them, 25 were influenza A (H1N1), 18 were influenza A (H3N2) and 18 were Yamayoto (B). Occupational exposure population monitoring, collection of 355 throat swab specimens, H5N1 and H7N9 avian influenza virus nucleic acid test results were negative; 310 serum samples were detected positive 26 antibody; influenza A H1N1 influenza-positive 11, type A 15 positive for H3N2 subtype antibodies, and no positive samples for H5N1 and H7N9 subtypes were detected. Conclusion The epidemic situation in Daxing District in 2013-2014 was relatively stable with no outbreaks and epidemics and no human bird flu outbreak was found.
