An investigation is underway to identify the source of an H5N1 bird flu infection.
However, it has been confirmed that the patient had contact with ill and deceased birds from backyard flocks.
This marks the first reported US case of H5N1 bird flu connected to backyard flock exposure.
Additionally, there have been 37 cases connected to dairy herds,
21 associated with poultry farms and culling operations,
and 2 cases where the source of exposure remains unknown.
