There are several ideas as to why flu spreads easier with some people than others. In an unexpected twist, researchers have found that a soft palate is an important site for shaping of airborne transmissibility.
Scientists could have finally found a universal cure for all types of influenza. Instead of the often, ineffective annual jabs, they may soon be able to produce a one-off, lifelong injection against all strains of this distressing and often fatal disease.
The pathogenic avian influenza H5 viruses are still moving, and perhaps evolving, through North American wild birds. How widespread the rate of infection in chickens will become is the subject of new research.
If the next pandemic is inevitable, and if entire categories of cancer are known to originate from infections, should society not be investing more money more urgently into viral research - or are we comfortable relying on vaccinations?
Bird flu appears to be on the rise across North America. Farmers detect H5N8 in a commercial turkey flock in California, while Canadian officials document the first known human importation of H7N9 to the country.
Scientists have demonstrated how changes in a flu virus common to Chinese poultry farms triggered the rise of the novel avian H7N9 influenza A virus that has sickened hundreds of people since 2013.
Increasing flu activity in the San Francisco Bay Area has prompted health officials in Solano County to remind residents that there's still time to get vaccinated against current strains of the virus.
Throughout the U.K., flu is circulating at its highest level for three years. The predominant type of flu virus - H3N2 - is a significantly different variant from the viral strain seen in high numbers last winter.
Certain types of avian influenza viruses have the potential to cause more severe disease in humans compared with others. This has come from new research which warns such viruses must be monitored carefully.
Researchers have discovered that the composition of the microorganisms in the gut affect effectivity of the seasonal flu vaccine. This potentially means that your gut bacteria affect how effective the vaccine will be within your own body.
During the 2013 flu season a new report highlights that antibiotics were inappropriately given to a large proportion of patients with influenza (a viral disease that is not helped by taking antibiotics).
A protein produced by the flu virus helps it outwit one of our body's natural defense mechanisms. This makes the protein a potentially good target for antiviral drugs directed against the influenza A virus.
Scientists have developed a formula that can predict the evolution of the seasonal flu for the next year. This will allow health providers to prepare and the public to be aware of the most serious instances of flu.
Speculation is swirling around the drug Tamiflu and whether it truly works to fight influenza

DRACO successfully treats viral infections. The microscope images show that in the left set of four photos, rhinovirus (the common cold virus) kills untreated human cells (lower left), whereas DRACO has no toxicity in uninfected cells (upper right) and cures an infected cell population (lower right). In the right set of four photos, dengue hemorrhagic fever virus kills untreated monkey cells (lower left), whereas DRACO has no toxicity in uninfected cells (upper right) and cures an infected cell
