New versions of the H5N1 virus are increasingly adept at spreading. Suggestions to either let it rip in poultry or vaccinate the birds could backfire.

As summer kicks into full gear and people are spending more time outside, there's one thing on many people's minds—ticks.

The bird flu virus remains a wild card that continues to threaten U.S. poultry and egg supplies while upping the ante with risk to human health.

Structural Biology Flu virus transcription caught in the act Cryo-EM experts make a movie of influenza’s replication machinery, which could lead to better antivirals by Louisa Dalton, special to ...

Influenza viruses share the same basic structure, but diversity within their genes and proteins means that they can mutate and morph to infect different hosts and evade immune defenses.

The H5N1 avian influenza virus is mutating to evade immune defenses in mammals following prior infection or vaccination.

With egg prices soaring, the US is considering vaccinating laying chickens, which have been hit particularly hard by the avian influenza outbreak.

The flu virus is changing in ways never seen before, increasing infections and raising concerns about vaccine effectiveness and public health risks.

As cases of seasonal influenza surge, health officials are closely monitoring a growing threat—the potential fusion of human and bird flu strains.

A strain of bird flu never seen before in the United States has been detected among poultry at a California farm. The virus, called highly pathogenic H5N9, is a type of avian influenza, otherwise ...

Flu viruses package essential functions into a small integral membrane protein known as M2. Such small membrane proteins represent major challenges for structural biology. A new study presented in ...

The virus uses this poly-basic site to bind to sulfated proteoglycans prior to entry into cells. NV-387 displays a copious amount ligands that mimic this sulfated structure, which is how this drug (NV ...
