The United States has confirmed its first case of highly pathogenic H5N9 avian influenza in poultry, following an outbreak at a duck meat farm in Merced County, California, the World Organization for Animal Health (WOAH) stated Monday.

Both H5N9 and H5N1 were detected at the duck farm in Merced County, according to tests conducted by the US Department of Agriculture (USDA) National Veterinary Services Laboratory. The event began on November 23, with clinical signs that included increased deaths in the ducks.

The H5N9 strain of avian influenza is much more rare than the H5N1 which has been responsible for most of the reported human cases and the first human death.
