A teenager in British Columbia has tested positive for H5N1 avian influenza and remains in critical condition, with health officials unable to identify the source of exposure despite extensive contact tracing.

“Last year we got several reports from tourists and scientists that they saw around six walruses dead here on the west side of Svalbard. Unfortunately, we couldn’t sample them as the dead walruses drifted away by the time we got to the place. But it’s not normal to get so many reported dead walruses in such a small area," said Christian Lydersen, senior scientist at the Norwegian Polar Institute. Now samples (collected by a Station Manager in July 2023) have tested positive for highly pathogenic avian influenza.

Norway reports a record high of 175 Lyme disease cases from January to June 2024, with uncertain causes attributed to weather conditions and increased tick awareness.

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.

A Lyme disease-carrying tick was found on a dog in Fort Simpson, N.W.T., with uncertainty about whether the tick originated locally or from a southern province.

The expedition revealed that gannets have easy access to plastic, as their nests are mostly made from plastic debris. Hundreds of dead gannets were also observed by the experts, with it being estimated that three factors played a role in their deaths: natural attrition, bird flu, and plastic pollution.

The virus was first reported among brown skua on Bird Island, off South Georgia. Since then, researchers and observers have reported mass deaths of elephant seals, as well as increased deaths of fur seals, kelp gulls and brown skua at several other sites. Researchers warn of one of ‘largest ecological disasters of modern times’ if the highly contagious disease reaches penguin colonies.

Avian influenza or “bird flu” is hitting Bay Area poultry farms hard, with a quarter of a million birds euthanized in Sonoma County this week alone. Mike Weber, the co-owner of Sunrise Farms in Petaluma, says around 82,000 of his egg-laying chickens had to be euthanized after birds started testing positive for avian flu.

The Food Authority noted that it might be possible that foxes are more susceptible to avian flu infections than mink. However, the agency also suggested that infection prevention protocols may not have worked as well at fox farms compared to facilities that raise mink. The authority has now confirmed avian influenza cases at a total of 42 fur farms in Finland.

Stanley, Falkland Islands, establishes a temporary control zone following the confirmation of its first avian flu case.

The H5N1 strain of avian flu has been detected on a poultry farm in Chilliwack, British Columbia, marking the first confirmed case in the province this fall and prompting increased precautions among poultry farmers.

Two cases of Highly Pathogenic Avian Influenza (HPAI) have been confirmed in Pocahontas and Guthrie counties in Iowa, but the U.S. Centers for Disease Control and Prevention (CDC) states that there is no public health concern.

There have been similar, even larger outbreaks of avian flue in seabird colonies in north Norway. In some cases, the losses were dramatic and major fractions of the colonies were wiped out. In Spitsbergen, avian flu was found for the first time in 2002, but the recent outbreak on Hopen is the largest one so far.

In Dillingham, Alaska, 19 cases of avian flu have been identified in common murres, with the virus still present in wild birds and genetic testing being conducted to determine if it is a new strain or a strain circulating in North America.

Thousands of turkeys in Sanpete County, Utah, have died from highly pathogenic avian influenza, leading to the quarantine and depopulation of the affected farm, with concerns about the potential impact on turkey sales during the upcoming holiday season.

A 50-year-old man in Cambodia has died from H5N1 bird flu, marking the second death from the virus in the country this year. Prior to his death about 50 chickens had died and were shared with neighbors to eat.
