The 1918 H1N1 Spanish Influenza pandemic was the most severe pandemic in modern history. Unlike more recent pandemics, most of the 1918 H1N1 virus' genome was derived directly from an avian influenza virus. Recent avian-origin H5 A/goose/Guangdong/1/1996 (GsGd) and Asian H7N9 viruses have caused several hundred human infections with high mortality rates. ⋯ Several GsGd H5 and Asian H7N9 viruses display molecular changes that potentiate transmission and/or exhibit ability for limited transmission between ferrets. However, the hemagglutinin of these viruses is unstable; this likely represents the most significant obstacle to the emergence of a virus capable of efficient airborne transmission. Given the global disease burden of an influenza pandemic, continued surveillance and pandemic preparedness efforts against H5 GsGd and Asian lineage H7N9 viruses are warranted.

Review[A review on the preparedness plans on influenza pandemics, by WHO and China: the current status and development].
Every influenza pandemic in history would end up with disastrous outcomes on mankind, of which the most notorious one was the "Spanish flu" pandemic in 1918. In the past century, with advanced knowledge on influenza viruses, laboratory technologies and surveillance methods, human beings were not as helpless when facing the influenza pandemic. ⋯ Since the "1918 influenza pandemic" , we had reviewed the evolution and development of plans regarding the preparedness and response on influenza pandemic issued by both WHO and China. We also emphasized on the variety of strategies which were linked to the preparedness and response at different historical stages, to provide reference for the pandemic preparedness of the disease, in the future.

[Seasonal, avian and pandemic influenza: are we prepared?]
China experienced a very high and severe influenza seasonal epidemics during the past winter and spring of 2017-2018 season. This year of 2018 is the 100(th) anniversary of the 1918 "Spanish influenza" pandemic, a series of papers under the topic "One Hundred Years of Influenza Pandemics" are produced to demonstrate the impact, characteristics and responses of the past influenza pandemics in global and China, to review the progress and experiences of influenza surveillance, prevention and control strategies, vaccination and antivirus in China, and to discuss the gap and challenges of the prevention, control and response to the seasonal influenza, human avian influenza infection and influenza pandemics. We hope this series could help to raise the awareness of the seasonal and pandemic influenza in publics, and to improve the pandemic preparedness in China.

Widespread epidemics, pandemics, and other risk-prone disasters occur with disturbing regularity. When such events occur, how should, and will, clinicians respond? The moral backbone of medical professionals-a duty to put the needs of patients first-may be sorely tested. ⋯ The decision to remain in or to leave a risky health care situation will ultimately depend on the provider's own risk assessment and value system. If history is any guide, we can rest assured that most clinicians will choose to stay, following the heroic example established through the centuries and continuing today.
