History of influenza pandemics in China during the past century / 中华流行病学杂志

Five influenza pandemics had occurred during the past century (1918 "Spanish flu" , 1957 "Asian flu" , 1968 "Hong Kong flu" , 1977 "Russian flu" and 2009 H1N1 Pandemic), accounting for hundreds of millions of people infected and tens of millions dead. China was influenced by all the five pandemics, and three of them (1957 "Asian flu" , 1968 "Hong Kong flu" and 1977 "Russian flu" ) were originated from China. The pandemics triggered the establishment of public health agencies and influenza surveillance capacities. In addition, more resources were allocated to influenza-related research, prevention and control. As a leader in the field of influenza, China should further strengthen its pandemic preparedness and response to contribute to global health.
