While the H5N1 bird flu keep spreading, there has been for the first time ever a reported H5N9 outbreak in the United States. This occurred on a duck farm in California

A California duck farm made headlines this week after the World Organization of Animal Health published a report by U.S. authorities that a strain of bird flu that scientists call H5N9 had been found among sick birds in the flock.

A new strain of bird flu has been detected in the United States, and it has sparked a lot of concerns among farmers and general population. Bird flu is a disease caused by 'avian influenza A virus' that usually spreads among birds,

H5N9 is a rare subtype of the influenza A virus that can cause highly pathogenic avian influenza (HPAI), also known as bird flu. It's a reassortment strain that originated from the H5N1, H7N9, and H9N2 subtypes.

First U.S. detection of virulent H5N9 strain, at a California duck farm, draws scrutiny as evidence of genetic reassortment that could trigger human outbreaks.

A new strain of a highly pathogenic and rare strain of bird flu has been reported on a duck farm in central California.

A new strain of H5N9 bird flu was detected at a commercial duck operation in California's Merced County. All the ducks were euthanized.

The U.S. is reporting its first confirmed outbreak of H5N9 avian flu at a California duck farm amid a global surge in its sister strain H5N1, according to a report from the Paris-based World Organization for Animal Health (WOAH).

The H5N1 virus has a ways to go before it can successfully jump to humans but that it doesn’t reduce the threat it poses.

U.S. authorities also detected the more common H5N1 strain on the same farm in Merced County, California, they said in a report to Paris-based WOAH, adding that the almost 119,000 birds on the

US officials are investigating the appearance of a strain of bird flu identified in the US for the first time, a worrying sign that the virus is evolving in ways that could make it harder to

According to the Centers for Disease Control and Prevention, 67 people in the U.S. have been infected with H5N1 bird flu. One person has died.
