Unique mutations in the H5N1 strain enhance replication in human cells and cause severe disease in mice. The virus has spread from birds to mammals, including dairy cows, and infected humans, with one ...

The patient in Louisiana who was hospitalized with severe bird flu illness was found to have a mutated version of the virus, the U.S. Centers for Disease Control and Prevention (CDC) announced last ...

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we ...

A genetic analysis of samples from the patient in Louisiana recently hospitalized with the country's first severe case of H5N1 bird flu show the virus likely mutated in the patient to become ...

Scientists have revealed parts of the genome that are especially vulnerable to mutations that occur very early on in development. These areas are in the initial portions of genes, where the cell tends ...

The Centers for Disease Control and Prevention (CDC) has identified mutations in a strain of the avian influenza virus H5N1, also known as bird flu, found in a Louisiana patient. The mutations were ...

Millions of birds in U.S. poultry farms and some cattle herds have been affected, but the overall risk to humans remains low. Still, a number of human cases have been documented as a new CDC report ...
