The Oregon Health Authority (OHA) has confirmed the first human case of Highly Pathogenic Avian Influenza (HPAI) in the state. This case is linked to a commercial poultry operation in Clackamas County, where an outbreak had previously been reported.
The Oregon Health Authority (OHA) has confirmed the first human case of Highly Pathogenic Avian Influenza (HPAI) in the state. This case is linked to a commercial poultry operation in Clackamas County, where an outbreak had previously been reported. The Centers for Disease Control and Prevention (CDC) has been closely involved in monitoring and managing the situation.
The outbreak in Clackamas County
The outbreak in Clackamas County affected approximately 150,000 birds at a commercial poultry operation. The Oregon Department of Agriculture (ODA) confirmed the presence of HPAI in the birds, prompting immediate action to contain the spread. The affected individual had close contact with the infected birds, which led to the transmission of the virus.
Human case details
The individual who contracted HPAI experienced only mild symptoms and has since fully recovered. They received antiviral treatment with oseltamivir, and household contacts were also given prophylactic treatment to prevent further spread. Health officials have emphasized that there is no evidence of person-to-person transmission, and the risk to the general public remains low.
Public health response
The Clackamas County Public Health Division has been actively monitoring people who were exposed to the outbreak. This proactive approach helped identify the human case early, allowing for prompt treatment and containment. The OHA, in collaboration with local public health authorities, the ODA, and the CDC, continues to monitor the situation closely.

Preventive measures
To reduce the risk of HPAI, health officials recommend avoiding contact with sick or dead birds or animals, as well as their droppings or litter. It is also advised not to consume unpasteurized or raw dairy products. The ODA provides personal protective equipment and training to farmworkers, while public health authorities offer symptom education and monitoring.
Impact on poultry industry
The outbreak has had a significant impact on the poultry industry in Oregon. The culling of infected birds has led to economic losses for farmers and disruptions in the supply chain. The ODA is working with affected farmers to provide support and resources to mitigate these losses. Additionally, there are ongoing efforts to enhance biosecurity measures to prevent future outbreaks.
Research and future preparedness
Researchers are studying the HPAI virus to better understand its transmission and develop more effective vaccines. The CDC and other health organizations are also working on improving surveillance systems to detect and respond to avian influenza outbreaks more rapidly. These efforts are crucial for preventing the spread of the virus and protecting both human and animal health.
Conclusion
The confirmation of the first human case of HPAI in Oregon underscores the importance of vigilance and prompt response in managing avian influenza outbreaks. While the risk to the public is low, continued monitoring and preventive measures are crucial to prevent further cases. Health authorities remain committed to ensuring the safety and well-being of the community through ongoing surveillance and education efforts.
