Avian Influenza (bird Flu)
Table of Contents
Avian influenza, commonly known as bird flu, is a disease caused by influenza viruses that naturally spread among wild aquatic birds worldwide. These viruses can infect domestic poultry and, less commonly, humans.
Different strains of avian influenza viruses exist, categorized based on two proteins: hemagglutinin (H) and neuraminidase (N). The most concerning strains for human health are those with pandemic potential, such as H5N1 and H7N9.
As of January 29,2026,the Centers for Disease Control and Prevention (CDC) reports ongoing surveillance of avian influenza viruses in the United States and globally. The current outbreak primarily affects poultry and wild birds, with a limited number of confirmed human cases.
Human Infection & Prevention
Human infections with avian influenza viruses are rare, but can occur when a person has close contact with infected birds or contaminated environments. The CDC states that the virus does not easily spread from person to person.
To reduce the risk of infection, the CDC recommends several preventative measures. these include avoiding contact with sick or dead birds, practicing good hygiene such as thorough handwashing after contact with poultry or wild birds, and avoiding touching eyes, nose, or mouth with unwashed hands.
The CDC specifically advises against handling wild birds, even if thay appear healthy, and recommends changing clothes and shoes after potential exposure to infected animals. For example, poultry workers are at higher risk and should follow strict biosecurity protocols.
2025 Louisiana Case
In January 2025,Louisiana reported the first confirmed human case of avian influenza (H5N1) in the United States. The patient, an adult, had exposure to poultry and developed symptoms consistent with avian influenza.
The Louisiana Department of Health confirmed the case and worked with the CDC to investigate potential exposures and implement public health measures.
The patient unfortunately died,highlighting the potential severity of avian influenza infection in humans. The CDC emphasized that this case did not indicate widespread human-to-human transmission, but underscored the importance of continued surveillance and preventative measures.
USDA response to Outbreaks
The United States Department of Agriculture (USDA) plays a critical role in controlling avian influenza outbreaks in poultry. The Animal and Plant Health Inspection Service (APHIS) implements measures such as depopulation of infected flocks, quarantine, and movement restrictions to prevent the spread of the virus.
As of January 29, 2026, APHIS continues to monitor and respond to avian influenza outbreaks across the country, working with state veterinary officials and poultry producers to minimize the impact on the industry and public health. In 2024, over 58 million birds
