[h=1]Sudden increase in human infection with avian influenza A(H7N9) virus in China, September-December 2016.[/h] Zhou L[SUP]1[/SUP], Ren R[SUP]1[/SUP], Yang L[SUP]2[/SUP], Bao C[SUP]3[/SUP], Wu J[SUP]4[/SUP], Wang D[SUP]5[/SUP], Li C[SUP]1[/SUP], Xiang N[SUP]1[/SUP], Wang Y[SUP]1[/SUP], Li D[SUP]1[/SUP], Sui H[SUP]1[/SUP], Shu Y[SUP]5[/SUP], Feng Z[SUP]6[/SUP], Li Q[SUP]1[/SUP], Ni D[SUP]1[/SUP].

[h=3]Abstract[/h] Since the first outbreak of avian influenza A(H7N9) virus in humans was identified in 2013, there have been five seasonal epidemics observed in China. An earlier start and a steep increase in the number of humans infected with H7N9 virus was observed between September and December 2016, raising great public concern in domestic and international societies. The epidemiological characteristics of the recently reported confirmed H7N9 cases were analysed. The results suggested that although more cases were reported recently, most cases in the fifth epidemic were still highly sporadically distributed without any epidemiology links; the main characteristics remained unchanged and the genetic characteristics of virus strains that were isolated in this epidemic remained similar to earlier epidemics. Interventions included live poultry market closures in several cities that reported more H7N9 cases recently.
