A new strain of human avian influenza, also known as bird flu, has been confirmed in Grays Harbor County, according to the Washington Department of Health.

Since highly pathogenic avian influenza virus (HPAIV) spread to the island of South Georgia in the sub-Antarctic in 2023, its breeding population of female southern elephant seals—the world's largest—has plummeted by nearly half, scientists reported yesterday in Communications Biology.

People have been warned not to touch dead or sick birds after a case of avian flu was confirmed in Nottinghamshire. The disease was found in a wild whooper swan in Shelford, according to Nottinghamshire County Council. Wild birds that migrate to the UK can carry the disease, which can lead to cases in poultry and other captive birds.

The avian flu is devastating marine mammal populations. A new survey finds that nearly half of breeding females in the world's largest population of southern elephant seals were killed by the virus.

Avian flu in humans may have made a reappearance after 9 months, according to a press release from the Washington State Department of Health.

The state has confirmed its second case of the highly pathogenic avian influenza (HPAI) in a migratory duck on Maui.

Over a two-day period, the presence of highly pathogenic avian influenza (HPAI) was confirmed in 10 commercial duck flocks in Indiana.

The beaches of South Georgia, a remote splinter of ice and rock in the South Atlantic, should be a place of deafening, chaotic life. Normally, the shores host the planet’s largest gathering of southern elephant seals, Mirounga leonina. They are the largest seals on Earth, and they come by the tens of thousands to fight, to mate, and to give birth.
