St. Jude Children’s Research Hospital-led study found naturally acquired mutations in the avian H3N8 flu virus allow the infection to spread in mammals via respiratory droplets; human immunity to the virus is lacking
Since its first identification in Asia, highly pathogenic avian influenza—H5N1—has caused significant alarm in the scientific community.
Every year the approach of flu season sets off a medical guessing game with life or death consequences.
The avian H7N9 influenza virus that emerged earlier this year in China is poorly adapted for sustained transmission between humans, suggesting that the current form of the virus is unlikely to cause a pandemic.
Avian influenza virus H7N9, which killed several dozen people in China earlier this year, has not yet acquired the changes needed to infect humans easily, according to a new study by scientists at The Scripps Research Institute (TSRI).
Researchers at the University of California, San Diego School of Medicine have shown for the first time how influenza A viruses snip through a protective mucus net to both infect respiratory cells and later cut their way out to infect other cells.
As China continues to battle an outbreak of avian influenza A (H7N9), a team of researchers from the University of Illinois at Chicago College of Medicine are among those looking for ways to intervene and bring an end to a disease that has so far killed more than 20 percent of those it has infected.
Scientists at Fred Hutchinson Cancer Research Center have uncovered a new mechanism by which influenza can infect cells – a finding that ultimately may have implications for immunity against the flu.
A new study has found that a novel avian-origin H7N9 influenza A virus, which has recently emerged in humans, attaches moderately or abundantly to the epithelium of both the upper and lower respiratory tracts.
A new technology is showing promise as the basis for a much-needed home test to diagnose influenza quickly, before the window for taking antiviral drugs slams shut and sick people spread the virus to others, scientists reported here today.
