A third person in the US has tested positive for bird flu linked to an outbreak in dairy cattle, indicating possible cow-to-human transmission.

The FDA found pasteurized milk containing inactive bird flu virus remnants from infected dairy cows, but maintains the milk supply is safe.

Cows at two Texas dairy farms have contracted bird flu, marking the first known instance of the disease in livestock, amidst recovery from devastating wildfires.

As of June 1, laboratory testing was still underway and had not yet fully confirmed which variant of Highly Pathogenic Avian Influenza the migratory bird had, and there are other possible detections this year, according to Alaska State Veterinarian Dr. Robert Gerlach.

The Ministry of Health of Chile notified WHO of the detection of human infection with avian influenza A(H5) virus. The patient is a 53-year-old male from the Region of Antofagasta in the north of Chile.

Two domestic cats in Oregon died in December 2022 from highly pathogenic avian influenza, the bird flu that began spreading rapidly in 2020. 

Pathologists say they’ve detected cases of the virus, commonly known as the bird flu, in three cats in Nebraska.

A pet dog in Oshawa has died after testing positive for avian flu, the Canadian Food Inspection Agency says. The CFIA says the number of documented cases of H5N1 — also known as avian flu — in other species like cats and dogs is low, and based on current evidence, the risk to the general public remains low.

Avian flu has decimated the marine creatures on the country’s Pacific coastline and scientists fear it could be jumping from mammal to mammal

Eight skunks found dead last month in Vancouver and Richmond tested positive for avian flu.

The Yukon is the latest place to be hit with avian flu cases as an outbreak continues to spread across the country. Officials from the department of environment said in a press release Friday that two waterfowl carcasses in southern Yukon tested positive for the H5N1 virus strand. The Yukon government is asking residents to report sightings of sick or dead birds to their TIPP line at 1-800-661-0525.

Most likely foxes become infected from feeding on deceased birds. In the past month, HPAI has been detected in red foxes in Michigan, Minnesota, Wisconsin, and Ontario in areas where the virus was also detected in wild birds.

During February and March, six new findings of highly pathogenic bird flu virus (HPAI) were made in sea eagles in the counties of Møre og Romsdal, Trøndelag, Nordland and Troms and Finnmark. Thus far, eight reliable detections have been made in sea eagles in Norway this bird flu season, which is unique in the European context.

An eagle that died in the Sitka National Historical Park this month tested positive for the avian influenza. A second eagle that died in the park was also tested for the virus, and results are pending. 

State Veterinarian Dr. Robert Gerlach says the Mat-Su case confirms that migrating birds have brought avian influenza to Alaska.

These cases represent the first detections of highly pathogenic avian influenza virus (HPAIV) H5N1 A/goose/Guangdong/1996 (Gs/GD) lineage in wild mammals in Ontario, Canada and in the Americas. One of the kits was found dead and the other was exhibiting severe neurological signs (including seizures) and died shortly after admission to a wildlife rehabilitation centre.

The Canadian Food Inspection Agency say avian influenza has been detected in additional poultry flocks in southern Alberta as well as in Saskatchewan.

The mortalities to date include a snow goose (Hyde County), redhead duck (Carteret County), red-shouldered hawk (Wake County) and bald eagle (Dare County).

The H5N8 virus was detected in sick and injured birds in February and early March this year, including in a swan found dead in Helsinki's Eläintarhanlahti park and a goshawk sent to Korkeasaari Wildlife Hospital from Kumpula. Several birds infected with avian influenza have been found in Uusimaa this winter.
