Genetic analyses of mutations of virus flu birds are necessary
Provided scientific opinions , evaluate mutations of viruses of bird flu and the potential of these viruses to spread to humans, along with recommendations for the health sector of animal and public health. The work of both agencies is based on extensive data, including genetic analysis, studies of cases in people and the presence of
antibodies, to determine present risks and eventual strategies for mitigation.

The problem of-common-domain poultry is significantly narrowing. There is one way
– the development of the world requires, that we remain sensitive and ensure ourselves, that Europe is prepared to respond to the threat of flu birds – said Pamela Rendi-Wagner, director ECDC. – ECDC supports the Member States EU/EEA in preparing, preventing and stopping thepotential future focuses on animals and humans. Having solid preparedness plans is key to protect public health in Europe.
The influenza virus has expanded its range
– W 2024 year. viruses of bird flu have expanded their range, infecting species, that had not been affected before. Our work identifies key mutations related to potential spread to humans, requiring quick detection and response. Collaboration and sharing data in the chain of involved entities remain essential in dealing with emerging situations – said Bernhard Url, fulfilling the director of executive EFSA.
In Poland in 2025 year there have already been 14 focuses of virus influenza birds in poultry. In the European Union with flu a significant problem still has been in the Italians, in a total 20 focalities recorded in poultry until 3 February 2025 year.
Here you can find an up-to-date map of virus virus flu in poultry in Poland.
34 mutations of influenza birds, which may threaten humans
Experts have developed a complete list of mutations, from which they have identified 34 genetic mutations, which may increase the potential of viruses of flu birds to spread to humans. Borrowing from molecular analysis and genomic surveillance, laboratories involving animals and public health are familiar with the list of mutations, which should be constantly updated, to monitor the appearance of strains, which potentially could transfer to people.
Scientific opinion identifies also, how the adaptation of viruses from influenza birds to suckers may be driven by factors such as genetic mutations, the mixing of genetic material between viruses and interaction with the immune response of the host, along with external factors, which may increase the risk of transmission to humans, such as human activity and environmental changes, which increase contact between wild animals, poultry, human animals and humans. Consolidation of agricultural production in small areas, practices low bio-security, deforestation, urbanization and global trade increase the risk of virus transmission from animals to humans.
Main Recommendations One Health:
- Genetic analysis: Use genetic sequencing to early.Detect mutations or adaptations of virus to suckers. Invest in systems, to quickly identify emerging viruses and mutations, which enable the spread from animals to humans.
- Surveillance over animals: Monitor sick or dead suckers associated with infected wild birds, poultry or suckers. Track unexplained diseases in high risk periods and in areas with flu birds.
- Surveillance over health public: Test exposed people and routinely send samples for further identification of subtype of flu. During focus on animals hospitals should increase surveillance and sensitivity, especially in the peak period of the flu season, when the risk of mixing of genetic material between viruses increases.
- Preventive measures: Implement solid biosecurity measures on farms, training staff, vaccination of poultry and prepare plans to react to fires. Providing that people exposed to risks comply with guidelines for vaccination against flu and treatment against virus.
- Measures preparedness health public: Raising awareness among high risk groups, the total society and training employees of health services in recognizing and treating patitis . Provide coordinated plans for response to cases in people. Develop guidelines and standard operational procedures for testing exposed persons and contacts patients, including protocols for prevention. Provide coordinated plans for response to cases in people as part of national prevention, preparedness and response.
First case of death of human in US to p
A fatal case of path in human had occurred in early January in US. The patient was transported to hospital after infection with a dangerous virus virus of bird influenza, known as H5N1. The State Department of Health in Louisiana reported, that a man had infected himself with the streak of birds and wild fowl.
The man was over 65 years old and
suffered other diseases. It was reported, that the investigation by their public health had no evidence of transmission of the virus from the person and
no other cases.
According to Center Control and Disease Prevention (CDC) since 2024 year in the US , there have been 66 cases of bird flu
H5N1.
