The Influenza A H3N2 virus subclade K represents a change in the basic structure of the influenza virus.

Influenza A virus (IAV) possesses a segmented, negative-sense RNA genome comprising eight distinct viral RNA (vRNA) segments. These segments form ribonucleoprotein (RNP) complexes that are selectively ...

On the surface of the influenza virus are two molecular "keys": hemagglutinin (HA) and neuraminidase (NA). They are the virus's lockpicks, the tools that let it slip into our cells and spread from one ...

The influenza virus manipulates the body's gene regulation system to accelerate its own spread. A new study also shows that an already approved drug could help strengthen immune defenses -- though its ...

In recent years, public health measures, surveillance, and vaccination have helped bring about significant progress in reducing the impact of seasonal flu epidemics, caused by human influenza viruses ...

Influenza A virus particles strategically adapt their shape-to become either spheres or larger filaments-to favor their ability to infect cells depending on environmental conditions, according to a ...

H5N1 avian influenza is highly pathogenic and has been devastating bird populations worldwide. It continues to do so, and is also moving into new animals, like skunks, bears, raccoons, cats, and dairy ...

In this prospective observational study, immune protection against H5N1 and H7N9 avian influenza virus (AIV) was almost absent prior to vaccination. However, seasonal influenza vaccines induced a ...

VIVIAN, LA - DECEMBER 12: With a temperature of 103.8, Asa Moore, 6, of Vivian, Louisiana is examined by John Messier, a physician's assistant, at the North Caddo Surgical and Medical Center for ...

New research led by Oregon Health & Science University reveals a promising approach to developing a universal influenza vaccine—a so-called "one and done" vaccine that confers lifetime immunity ...
