SAN DIEGO—The San Diego Humane Society has taken precautions against bird flu as the avian-borne disease spreads throughout the United States and Southern California, the organization announced Oct. 17.
Highly pathogenic avian influenza H5N1—also known as the bird flu—is spreading in domestic poultry and wild birds and has now been confirmed in Los Angeles and Orange counties. The disease poses little risk to humans, but is highly contagious among susceptible bird species.
