First childhood flu helps explain why virus hits some people harder than others
Why are some people better able to fight off the flu than others? Part of the answer, according to a new study, is related to the first flu strain we encounter in childhood.Scientists from UCLA and the University of Arizona have found that people ’s ability to fight off the flu virus is determined not only by the subtypes of flu they have had throughout their lives, but also by the sequence in which they are been infected by the viruses. Their study is published in the open-access journal PLoS Pathogens.The research offers an explanation for why some people fare much worse than others when infected with the same strain...

Previous influenza virus exposures enhance susceptibility in another influenza pandemic
(McMaster University) New data analysis suggests that people born at the time of the 1957 H2N2 or Asian Flu pandemic were at a higher risk of dying during the 2009 H1N1 Swine Flu pandemic as well as the resurgent H1N1 outbreak in 2013-2014. And it is not the first time this has happened. (Source: EurekAlert! - Infectious and Emerging Diseases)

Is a new flu pandemic just three mutations away?
Conclusion
This laboratory study analysed an H7N9 strain of bird flu. Researchers wanted to explore whether a particular change to the surface proteins of a virus was capable of allowing the strain to bind to human tissue. This would theoretically lead to human-to-human transmission of the flu virus.
It is worth noting that this ability to attach to human cells does not necessarily mean a mutated bird flu virus will be able to infect, replicate and transmit between humans. Other changes would also be required.
However, they were unable to further investigate whether this surface change could lead to human-to-human transmis...

Identification of emerging threats may be aided by 1950s pandemic bird flu virus
St. Jude Children's Research Hospital scientists have evidence that descendants of the H2N2 avian influenza A virus that killed millions worldwide in the 1950s still pose a threat to human health, particularly to those under 50. The research has been published in an advance online edition of the Journal of Virology.The study included 22 H2N2 avian viruses collected from domestic poultry and wild aquatic birds between 1961 and 2008, making it the most comprehensive analysis yet of avian H2N2 viruses.Researchers reported the viruses could infect human respiratory cells.
