Bird flu puts organic chickens into lockdown from Pennsylvania to France
April 29 (Reuters) - The first known human case of H5 bird flu in the United States has appeared in a person in Colorado, the Centers for Disease Control and Prevention (CDC) said on Thursday.
The person tested positive for avian influenza A(H5) virus and was involved in the culling of poultry presumed to have had H5N1 bird flu, the CDC said in a statement.
"This case does not change the human risk assessment for the general public, which CDC considers to be low," the agency added.
