Recent reports from the UK confirm a surge in bird flu cases, particularly affecting wild birds. A recent human case has been detected in England, just days after strict measures were implemented to contain the virus’s spread among wild birds and poultry in England and Scotland.
While the outbreak has affected birds, with the avian influenza virus H5N1 spreading through wild bird populations and poultry farms, health experts emphasize that the risk to humans remains extremely low. The virus primarily affects birds, with only a handful of strains capable of causing severe illness. H5N1, a highly pathogenic strain, has been a concern globally since the late 1990s for its occasional transmission to humans, though this remains rare.
Influenza viruses are highly specialized to infect certain species. While humans contend with seasonal flu strains, birds, especially wild ones like shorebirds and waterfowl, face their own set of avian flu viruses. H5N1 is known to cause mass bird die-offs but rarely infects humans. The most recent case in a poultry worker in England is considered an isolated event resulting from close contact with infected birds.
The UK has responded with preventive measures, including avian influenza prevention zones in England, Scotland, and Wales, requiring poultry owners to keep birds indoors to limit their exposure. These measures will help reduce the risk to farmed birds but will not eliminate the threat entirely.
Health experts point out that for the general public, the risk remains minimal. Those who do not come into direct contact with wild or farmed birds are unlikely to be affected. It is important, however, to avoid handling dead birds, particularly waterfowl, and to prevent pets from scavenging bird carcasses.
The virus poses no danger to those who consume properly cooked eggs or poultry, as influenza viruses are quickly destroyed by heat. However, the outbreak has already led to some disruptions in the supply of free-range eggs and price increases, a situation already seen in the US, which is facing its own H5N1 outbreak.
Globally, H5N1 continues to cause problems, with outbreaks in mammals such as seals and sea lions in South America, and even dairy cattle in the US. Human infections have been reported, though they are rare, with most cases occurring in individuals with close contact with infected animals.
Currently, there is no evidence of human-to-human transmission of H5N1 in the UK or elsewhere. Should this change, surveillance systems are in place to detect such a development, and antiviral treatments and vaccines are available to mitigate the threat.
While bird flu remains a concern for bird populations worldwide, experts stress that it is not a significant risk to human health at this time. The focus remains on preventing further spread among animals and monitoring any potential mutations that could pose a more substantial risk to humans in the future.

Although the risk to humans is currently low, it is important to follow recommended precautions, particularly for individuals who work with birds or encounter sick or dead wildlife.
