Cats Dying Across Poland Test Positive for Bird Flu, WHO Says

An unusual number of cats are dying across Poland, and authorities found more than half of those tested harbored the worrisome strain of bird flu known as H5N1, the World Health Organization said.

Of 47 samples tested — including one wild feline in captivity — 29 were positive for the H5N1 flu, marking the first report of “high numbers of infected cats over a wide geographical area within a country,” the WHO said in a statement.
