1,2 In 2009, a novel strain of influenza A (H1N1) virus was identified,3 and pregnant women also were found to be at greater risk for influenza-related complications from this new virus.4 As a result, during the 2009-10 influenza season, two separate influenza vaccines were recommended to...
Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, said in winter respiratory diseases are more common, including influenza A, influenza B, novel coronavirus, respiratory syncytial virus, adenovirus and mycoplasma. The immunity established after being inf...
Annual epidemics caused by seasonal influenza remain a public health concern, typically peaking between December and March in the Northern Hemisphere (NH) and in July or August for the Southern Hem...
During the COVID-19 pandemic, levels of seasonal influenza virus circulation were unprecedentedly low, leading to concerns that a lack of exposure to influenza viruses, combined with waning antibody titres, could result in larger and/or more severe post-pandemic seasonal influenza epidemics. However,...
It has long been recognized that influenza virus-specific CD4(+) T cells are important in protection from infection through direct effector mechanisms or by providing help to B cells and CD8(+) T cells. However, the seasonal influenza vaccine is poor at inducing CD4(+) T-cell responses and...

Influenza virusAlthough seasonal influenza viruses circulate globally, prevention and treatment occur at the level of regions, cities, and communities. At these scales, the timing, duration and magnitude of epidemics vary substantially, but the underlying causes of this variation are poorly understood. ...
The serial interval (SI) of human influenza virus infections is often described by a single distribution. Understanding sources of variation in the SI could provide valuable information for understanding influenza transmission dynamics. Using data from a randomized household study of nonpharmaceutical inter...
