Bird Flu Alert: H5N1 Detected in Wild Birds Across ireland
The Department of Agriculture, Food and the Marine (DAFM) has issued a stark warning to the public following the detection of the highly pathogenic avian influenza (HPAI) H5N1 virus in wild birds across Ireland. The Health Service Executive (HSE) is echoing this advice, urging people to avoid touching or handling sick or dead wild birds due to the risks of avian influenza.
Two recent cases of the H5N1 strain have been identified in buzzards—one in the west of Ireland in early December and another in the east in late December. These are the first wild bird detections in the country since September 2023, signaling a resurgence of the virus.

Avian influenza, commonly known as bird flu, primarily affects wild birds and poultry but can occasionally infect mammals and humans. The H5N1 strain, a highly pathogenic form of the virus, is especially concerning. Since 2003, there have been nearly 1,000 human cases of H5N1, with a fatality rate of approximately 50%.
Why is This a Concern?
While it is rare for humans to contract bird flu, the potential consequences are severe. The HSE highlights three key reasons to prevent human infections:
- H5N1 can cause serious, sometimes fatal, disease in people.
- During flu season, the mixing of avian influenza and seasonal flu in a person could allow the virus to mutate, potentially enabling human-to-human transmission.
- If a person becomes infected, the virus could spread to Irish poultry flocks, causing widespread illness and death among birds.
What Should the Public Do?
The DAFM and HSE are urging the public to:
- Avoid touching sick or dead wild birds.
- report any sightings of sick or dead birds using the avian Check app.
While not all reported birds will be collected for testing, this data is crucial for surveillance and risk assessment efforts.
Monitoring and Prevention
Individuals who handle sick or dead birds found to be infected with avian influenza will be monitored for 10 days. Depending on their risk level, they may be offered antiviral medication or vaccination.

A Growing Threat Across Europe
The resurgence of HPAI in Ireland is part of a broader trend across Europe.In 2024,several outbreaks were reported on poultry farms in the UK,underscoring the need for vigilance.

By following these guidelines,we can collectively reduce the risk of avian influenza spreading further.Let’s stay alert and protect both human and animal health.
Bird Flu Alert: Expert Insights on H5N1 Resurgence in Ireland
In light of the recent detection of the highly pathogenic avian influenza (HPAI) H5N1 virus in wild birds across Ireland, world-today-news.com sat down with Dr. Fiona O’Sullivan,a leading virologist specializing in zoonotic diseases,to discuss the implications of this resurgence. Dr. O’Sullivan shares her expertise on the risks, preventive measures, and the broader context of avian influenza in Europe. Here’s what she had to say.
Understanding Avian Influenza: What is H5N1?
Senior Editor: Dr. O’Sullivan, thank you for joining us. To start, could you explain what avian influenza is and why the H5N1 strain is particularly concerning?
dr. Fiona O’Sullivan: Absolutely. Avian influenza, or bird flu, is a viral infection that primarily affects birds, both wild and domesticated. The H5N1 strain is a highly pathogenic form of the virus, meaning it can cause severe disease and high mortality rates in birds. What makes it particularly concerning is its potential to infect humans. While human cases are rare, they can be severe, with a fatality rate of around 50% since 2003. The virus can also mutate, which raises the risk of it becoming more transmissible among humans.
Recent Cases in Ireland: What Does This Mean?
Senior Editor: Two recent cases of H5N1 were detected in buzzards in Ireland—one in the west and another in the east. What does this resurgence signify?
Dr. Fiona O’Sullivan: These detections are notable as they mark the first cases in wild birds in Ireland as September 2023.It suggests that the virus is circulating again in the wild bird population, which could pose a risk to poultry and, indirectly, to humans. Wild birds are natural reservoirs for avian influenza, and their migration patterns can spread the virus over large distances. This resurgence underscores the need for heightened surveillance and public awareness.
Human Health Risks: Why Should We Be Concerned?
Senior Editor: the HSE has highlighted the risks of human infection. Can you elaborate on why this is a concern, even though cases are rare?
Dr.Fiona O’Sullivan: Certainly. While human infections are rare, the consequences can be severe. H5N1 can cause serious respiratory illness and has a high fatality rate. Additionally, if someone infected with seasonal flu also contracts avian influenza, the two viruses could mix, leading to a new strain that might be more easily transmitted between humans. This is a scenario we want to avoid at all costs. Furthermore, human infections could lead to the virus spreading to poultry flocks, causing significant economic and agricultural impacts.
Public Advice: What Should People Do?
Senior Editor: The DAFM and HSE are urging the public to avoid touching sick or dead wild birds and to report sightings via the Avian Check app. Why is this significant?
Dr. Fiona O’Sullivan: this advice is crucial for several reasons. First, avoiding contact with sick or dead birds reduces the risk of human exposure to the virus. Second, reporting sightings helps authorities track the spread of the virus and implement targeted measures to contain it. While not all reported birds will be tested, the data collected is invaluable for surveillance and risk assessment. It’s a simple yet effective way for the public to contribute to public health efforts.
Monitoring and Prevention: What’s Being Done?
Senior Editor: Can you explain how individuals who handle infected birds are monitored, and what preventive measures are in place?
Dr. Fiona O’Sullivan: Individuals who handle infected birds are monitored for 10 days to ensure they don’t develop symptoms. Depending on their level of exposure, they may be offered antiviral medication or vaccination as a precaution. This is part of a broader strategy to prevent human infections and contain the virus. Additionally, poultry farmers are advised to maintain strict biosecurity measures to protect their flocks from potential exposure.
A Broader Trend: H5N1 in Europe
senior Editor: This resurgence isn’t isolated to Ireland. Can you provide some context on the situation in Europe?
dr. Fiona O’Sullivan: Unluckily, Ireland isn’t alone in facing this threat. In 2024, several outbreaks of HPAI have been reported in poultry farms across the UK and other parts of Europe. This highlights the need for regional cooperation and vigilance. Wild birds don’t recognize borders, so a coordinated approach is essential to mitigate the spread of the virus.
Final Thoughts: Staying Informed and safe
Senior editor: What’s your final message to the public regarding avian influenza?
Dr. Fiona O’Sullivan: My message is simple: stay informed and follow the guidelines provided by the DAFM and HSE. Avoid contact with sick or dead birds, report sightings, and remain vigilant. By working together, we can reduce the risk of avian influenza spreading further and protect both human and animal health. For more information, I encourage everyone to visit the HSE’s dedicated page on avian influenza.
Senior Editor: Thank you, Dr. O’Sullivan, for your valuable insights. This has been an enlightening discussion, and we appreciate your time.
Dr. Fiona O’Sullivan: Thank you for having me.It’s critically important to keep the public informed, and I’m glad to contribute to that effort.
