Breaking: First U.S. Death from Bird Flu Reported; Public Risk Remains Low, Experts Caution
In a significant development, Louisiana‘s health authority has confirmed the first human death linked to bird flu in the United States. The victim, aged over 65, had underlying health conditions and was hospitalized since mid-December. The Centers for Disease Control and Prevention (CDC) had previously identified this case as the country’s first serious human infection caused by the H5N1 virus.
"While the risk to the general public remains low, individuals who work with birds, poultry, or cattle, or have recreational exposure to them, face a higher risk," the Louisiana Department of Health stated, as reported by AFP.
The patient was exposed to the H5N1 virus through a combination of backyard non-commercial bird flocks and wild birds. Authorities report no further H5N1 infections or evidence of human-to-human transmission in the state.
This announcement comes just days after the federal government allocated an additional $306 million to bolster H5N1 monitoring and related research, a move criticized by some amid growing concerns about the issue under the Biden administration.
Scientists worry that the virus could mutate into a more transmissible form, potentially triggering a deadly pandemic. Since early 2024, the CDC has recorded 66 bird flu cases in humans across the U.S.
Dr. Jennifer Nuzzo, a Brown University epidemiology professor, expressed concern, stating, "We have a lot of data showing that this virus can be deadly, deadlier than many viruses we’re worried about."
Genetic sequencing of the H5N1 virus from the Louisiana patient shows differences from the strain found in many dairy herds nationwide. A small segment of the virus in the patient suggests potential mutations adapting to human respiratory tracts, although researchers emphasize that this is not the sole factor influencing the virus’s transmissibility or spread among humans.
First detected in 1996, the H5N1 virus has seen a sharp increase in outbreaks among bird flocks since 2020, with growing numbers of mammal species affected. Since 2003, the World Health Organization has reported over 950 human bird flu cases across 24 countries, with the majority occurring in China and Vietnam.
Dr. Nuzzo noted, "The announcement of a death in the U.S. does not change my perspective, but underscores my grave concerns about the relatively uncontrolled spread of this virus and the urgent need to step up efforts to prevent human infections."
