A substantial variety of felines in Poland have just recently passed away after capturing an extremely pathogenic form of bird influenza. The infection is a subtype of avian influenza A referred to as H5N1. While cases of H5N1 infections in felines have actually been recorded before, this is the first circumstances of a larger break out affecting many cats across a broad geographic area.
A group of forty-six felines and one slave caracal, a wild feline also called the desert lynx, underwent testing for H5N1. Out of the total, twenty-nine felines checked positive, the World Health Organization (WHO) stated. Eleven felines passed away from the illness, while an additional fourteen needed to be euthanized due to the development of viral signs.

” The risk of human infections following direct exposure to contaminated cats at the national level is evaluated as low for the general population, and low to moderate for feline owners and those occupationally exposed to H5N1-infected cats, such as vets, without making use of suitable personal protective equipment,” a WHO statement checks out.
The European Food Safety Authority (EFSA) encouraged animal owners to take preventative measures to protect their animals. The EFSA recommended keeping domestic felines and dogs away from diseased or dead animals to avoid possible exposure. In areas where the disease has been validated in wild birds, they have actually advised to restrict cats inside your home and keep pet dogs on leashes.
While human risk of contracting the virus in Poland is currently thought about low, people who own felines or come into contact with felines bring the illness are categorized as having a moderate threat. As of now, there have actually been no reported signs among those who have touched with cats favorable for H5N1.
Tracing the origin
In 2022, 67 nations on 5 continents reported H5N1 avian influenza outbreaks in both poultry and wild birds. This led to over 131 million domestic poultry either being or passing away culled in impacted farms and villages. This year another 14 countries reported outbreaks, mostly in the Americas, as the disease continued its spread.
The European Centre for Disease Prevention and Control launched a report expressing uncertainties about the source of infection, and the WHO said that the origin stays unknown. It suggested different possibilities, consisting of contact with contaminated birds or their environments, intake of infected birds, or ingesting infected food.
A significant number of felines in Poland have just recently died after capturing an extremely pathogenic form of bird influenza. While cases of H5N1 infections in felines have been recorded previously, this is the very first instance of a larger outbreak affecting many felines across a broad geographical area.
The World Organization for Animal Health (WOAH) said the extensive distribution of cases recommends that cat-to-cat transmission is not the primary mode of spread. Instead, it seems to be connected to a common source of infection. Experts have actually also highlighted that the infection showed two anomalies that promote better transmission in mammals.
The H5N1 bird influenza viruses initially emerged in 1996 and have actually because been causing outbreaks in bird populations. From 2020 onwards, a variation of these has actually been accountable for an unmatched variety of deaths in wild birds and poultry across numerous nations in Africa, Asia, and Europe. The infection now keeps broadening.
“There is a current paradigm modification in the ecology and epidemiology of bird influenza which has heightened worldwide concern as the illness spread to new geographical regions and triggered uncommon wild bird die-offs, and alarming increase in mammalian cases,” Gregorio Torres, head of science at WOAH, stated in a media declaration earlier this week.
Out of the 24 felines that checked positive for H5N1, 13 were found to have been fed raw poultry meat.
Local media outlets have connected the break out to infected meat. Out of the 24 felines that checked positive for H5N1, 13 were discovered to have been fed raw poultry meat. A female in southern Poland, for example, fed her feline raw chicken from the grocery store. After consuming, the feline became sick and ultimately passed away.
A group of forty-six cats and one captive caracal, a wild feline also known as the desert lynx, underwent screening for H5N1. In areas where the illness has actually been confirmed in wild birds, they have advised to restrict cats indoors and keep pet dogs on leashes.
