Irish health authorities are advising the public to steer clear of sick or deceased wild birds as the threat of avian influenza, or bird flu, continues to rise. This warning follows the revelation of two cases of the highly contagious H5N1 strain in wild buzzards,confirming the virus’s presence in Ireland’s avian population.
Bird flu is a viral infection that primarily affects birds but can occasionally jump to humans and other mammals. The H5N1 strain, in particular, is notorious for its severity, causing high mortality rates among birds and posing a significant risk to human health. As 2003, nearly 1,000 human cases of H5N1 have been reported globally, with a fatality rate of around 50%.
The recent detections in Ireland—one in the west in early December and another in the east later that month—mark the first instances of the virus in wild birds since September 2023.These findings align with a broader surge in avian influenza activity across Europe, including outbreaks on poultry farms in the UK in 2024.
While the risk of human infection remains low, health officials are urging caution. “It is indeed very unusual for people to catch bird flu, but it can happen,” stated the HSE.Even though the virus is not currently known to spread between humans, experts warn that mutations could change this in the future. The potential for the virus to mix with seasonal flu strains in humans raises concerns about the emergence of a more transmissible variant.
To reduce risks, the HSE is reinforcing guidance from the Department of Agriculture, Food, and the Marine (DAFM):
- Avoid touching or handling sick or dead wild birds.
- Report any sightings of sick or dead birds using the Avian Check app. While not all birds will be tested, the data collected helps with surveillance and risk assessment efforts.
Individuals who come into contact with infected birds may be monitored for 10 days and could be offered antiviral medication or vaccination if necessary. This precautionary measure aims to prevent potential transmission to humans and protect Ireland’s poultry industry from outbreaks.
For those seeking more information on avian influenza, resources are available through the HSE and DAFM websites. Staying informed and following public health advice are crucial steps in safeguarding both human and animal health during this period of heightened risk.

Interview with Dr. Fiona O’Connell: Understanding the Rising Threat of Avian Influenza in Ireland
Archyde News: Dr. Fiona O’Connell, thank you for joining us today. As a leading epidemiologist specializing in zoonotic diseases, can you explain why the recent detection of the H5N1 strain in wild buzzards is causing concern among Irish health authorities?
Dr. Fiona O’Connell: Thank you for having me. The detection of H5N1 in wild buzzards is concerning as it confirms that the virus is circulating in Ireland’s avian population. H5N1 is a highly pathogenic strain, meaning it can cause severe illness and high mortality rates in birds. While the risk to humans remains low, the virus has the potential to jump species, as we’ve seen in nearly 1,000 human cases globally since 2003. The fact that it’s now present in wild birds increases the likelihood of exposure, especially for those who work closely with poultry or spend time in rural areas.
The Broader Context: Avian Influenza in Europe
Archyde News: These cases in Ireland come amid a surge in avian influenza activity across Europe. How does this fit into the larger picture?
Dr.Fiona O’Connell: europe has been experiencing a notable uptick in avian influenza outbreaks, particularly in poultry farms. The UK, for example, saw several outbreaks in 2024. This pattern suggests that the virus is spreading more widely, likely due to migratory bird movements and environmental factors. Ireland’s recent cases are part of this broader trend, and they highlight the importance of vigilance and proactive measures to prevent further spread.
Human Health Risks and Precautions
Archyde News: What are the risks to human health, and what precautions should people take?
dr. Fiona O’Connell: The risk of human infection is currently low, but it’s not zero. H5N1 can infect humans through direct contact with infected birds or contaminated environments. That’s why it’s crucial to avoid touching sick or dead wild birds and to report sightings using the Avian Check app. For those who may have been exposed,health authorities are recommending monitoring for 10 days and,in some cases,offering antiviral medication or vaccination as a precautionary measure.
The potential for Mutation
Archyde News: one of the biggest concerns is the potential for the virus to mutate and become more transmissible among humans. How likely is this scenario?
Dr.Fiona O’Connell: While the virus is not currently known to spread between humans, the possibility of mutation is a real concern.Influenza viruses are highly adaptable, and if H5N1 were to mix with a seasonal flu strain in a human host, it could lead to a more transmissible variant. This is why ongoing surveillance and research are so critical. We need to stay ahead of any potential changes in the virus’s behavior.
Thought-Provoking Question for readers
Archyde News: As we wrap up, here’s a question for our readers: Given the interconnectedness of human, animal, and environmental health, what steps do you think individuals and communities can take to reduce the risk of zoonotic diseases like avian influenza? We’d love to here your thoughts in the comments below.
Dr. Fiona O’Connell: That’s a great question.I believe education and awareness are key. By understanding the risks and following public health advice, individuals can play a vital role in preventing the spread of diseases like avian influenza. Communities can also support local efforts to monitor and control outbreaks, ensuring a coordinated response to emerging threats.
Archyde News: Thank you, Dr. O’Connell, for your insights. Stay informed and stay safe, everyone.
