Bird flu's emergence calls for caution

Louisiana has recorded the nation’s first severe human infection of H5N1, also known as highly pathogenic avian influenza or bird flu, according to the Centers for Disease Control and Prevention. This development highlights the importance of vigilance in protecting both human health and the state’s animal industry as well as backyard flocks.
Dr. Christine Navarre, LSU AgCenter extension veterinarian, said highly pathogenic avian influenza, or HPAI, is a severe, highly contagious viral disease that affects both wild and domestic birds. It also has been spreading among dairy cattle.
“The virus can cause significant mortality in poultry, leading to substantial economic losses and posing a threat to food security,” she said. “The virus has been detected in more than 200 mammal species, including people.”
With a few exceptions, human cases are generally sporadic and cause only mild illness. However, HPAI viruses have the potential to mutate and acquire the ability to transmit efficiently between humans.
Domestic poultry such as chickens, turkeys, ducks and geese are highly susceptible to HPAI. taminated equipment, manure and clothing.
