A patient in Louisiana has been hospitalized with the first severe case of avian influenza A(H5N1) virus (“H5N1 bird flu”) in the US. CDC confirmed the presence of the virus on December 13, 2024.\n\n
USGS Biologist Science Tech Brooke Hill releases a Western Sandpiper after testing it for the highly pathogenic H5N1 avian influenza in Sonoma, California, on August 16, 2006\n\n\n
An investigation is underway to identify the source of an H5N1 bird flu infection. However, it has been confirmed that\u00a0the patient\u00a0had 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.\n\n
Additionally, there have been\u00a037 cases connected to dairy herds, 21 associated with poultry farms and culling operations, and 2 cases where the source of exposure remains unknown.\n\n
Genomic analysis of the H5N1 bird flu virus from the Louisiana patient shows it belongs to the D1.1 genotype, linked to recent detections in US wild birds, poultry, and human cases in Canada and Washington.\n\n
This differs from the B3.13 genotype seen in dairy cows, some human cases, and poultry outbreaks. The CDC is conducting further sequencing and\u00a0virus isolation from the sick patient.\n\n
A single severe H5N1 bird flu case in a person is not unusual, as this virus has caused serious illness and fatalities in other countries, including in 2024. There is still no evidence of person-to-person transmission. Additionally, the CDC maintains that the overall public health risk from H5N1 bird flu is low.\n\n
