Salt Lake City, Utah – Wildlife officials in Utah have reported the presence of highly pathogenic avian influenza in birds and other wildlife in 10 counties since November. The virus has been identified in over 100 wild birds, including three red foxes, one mountain lion, and several skunks across various counties such as Box Elder, Cache, and Davis. This recent outbreak has also affected counties like Box Elder, Emery, and San Juan, which had not previously recorded any cases since the national outbreak began in early 2022.
According to the Utah Division of Wildlife Resources, there was a decrease in new cases of avian flu in wild birds between January 2024 and November 2024. However, a resurgence in cases has been observed since last fall, prompting concerns among officials. The impact of the virus extends beyond bird species to include other wildlife, such as foxes, mountain lions, and skunks, highlighting the need for continued monitoring and prevention efforts.
Recent reports indicate that over 15,000 eared grebes have died within the Great Salt Lake ecosystem due to the virus. While the outbreak has led to 122 confirmed cases among grebes, the overall impact on the migrating population of 4 million grebes remains uncertain. Wildlife officials have reassured the public that the outbreak should not significantly affect the annual migration patterns of the grebes through the region.
In addition to grebes, the virus has also affected other bird species like Canada and snow geese, hawks, gulls, and owls. The spread of the virus has raised concerns about potential implications for farm animals, with reports of infected cattle, chickens, and turkeys across the state. Measures have been taken to contain the outbreak, including the culling of 1.8 million chickens in Cache County to prevent further spread of the virus.
While the human risk of contracting the virus is considered low, there have been 68 reported cases among individuals, including one death, since 2024. Experts emphasize the importance of maintaining hygiene practices, such as regularly cleaning birdfeeders and birdbaths, to prevent the spread of the virus. Vigilance is advised for individuals who come across multiple dead waterfowl or shorebirds, as well as scavengers or raptors, who are urged to report their findings to the nearest wildlife division office for testing. Overall, efforts are ongoing to monitor the impact of the virus on wild bird populations and to prevent further spread within the state.
