Abstract:

【Abstract】 Objective  To predict the epidemic trends of influenza in mainland in China in 2016 through retrospective analysis of the surveillance data and epidemic characteristics in 2015. Methods  The data on influenza-like illness(ILI) and its outbreak were obtained from Chinese Influenza Surveillance Information System (CISIS) and Chinese Public Health Emergency Management Information System (PHEMIS)in 2015, and statistically analyzed. Results  Influenza was peaked in summer in south China in 2015, and maintained at a low level in north China, with subtype of influenza A(H3N2) being dominated. Provinces in both south and north China were in epidemic seasons in winter and spring of 2015 and 2016, and the viruses were associated with influenza A(H1N1/pdm09 virus, H3N2) and B. Conclusion  Influenza may be active and peaked in the third of February 2016, and the prevalence is associated with influenza A(H1N1/pdm09 virus, H3N2) and B viruses, with subtype A(H1N1)pdm09 virus being predominant strain.
