DWR: Avian flu confirmed in two foxes in Salt Lake County

SALT LAKE CITY — After the first case of avian flu in wild birds was confirmed last month in Cache County, The Utah Division of Wildlife Resources has confirmed that the virus has spread to two foxes in Salt Lake County.

As of June 8, 25 wild birds have tested positive for avian flu in six counties in Utah, including Cache, Weber, Salt Lake, Utah, Tooele and Carbon counties. The birds affected include raptors and waterbirds, specifically Canada geese, great horned owls, hawks, pelicans, turkey vultures and ducks. Test results from other bird mortalities are currently pending.

On May 24, a red fox was found dead in a homeowner’s yard in Murray, and another red fox was found dead just two days later in a yard in Taylorsville. They were both collected by DWR officials and sent to the Utah Veterinary Diagnostic Laboratory in Logan for testing. Samples were then sent to the National Veterinary Services Laboratory in Ames, Iowa, which confirmed they had contracted the highly pathogenic avian influenza. Both foxes tested negative for rabies.

While no dead birds were discovered near where the foxes were found, it is suspected the foxes each came into contact with or ate a bird that was infected with the virus.

“While it does happen, it’s not very common for wildlife species other than birds to get highly pathogenic avian influenza,” DWR Veterinarian Ginger Stout said. “Some states have had one or two cases in wild mammals, but it’s pretty infrequent, and it seems to affect younger animals more often when it does occur.”

High pathogenic avian influenza viruses are very contagious among birds and can cause rapid and high mortality in domestic birds, such as chickens, turkeys and domestic ducks. These viruses occasionally kill wild birds, as well. The most common wild birds impacted by the virus are typically waterfowl, shorebirds, raptors and scavengers (which include birds like hawks, owls, ravens and vultures). There are usually few symptoms in waterfowl and shorebirds, but the virus can kill raptors and scavengers quickly. The virus is spread among birds through nasal and oral discharge, as well as fecal droppings. It can be spread to backyard poultry and domestic birds through contaminated shoes or vehicles.

Songbirds are not typically affected by avian flu, so people shouldn’t have to remove their bird feeders unless they also have backyard chickens or domestic ducks, which are susceptible to the virus. However, it’s always recommended to regularly clean bird feeders and baths.

Although the current strain of the avian flu presents a low risk to people, it has been confirmed in at least one person in Colorado during this most recent outbreak. Visit the CDC website for more information on keeping yourself safe.

“If anyone finds a group of five or more dead waterfowl or shorebirds — or any individual dead scavengers or raptors — they should report it to the nearest DWR office and absolutely make sure not to touch the birds or pick them up,” Stout said. “Just report it to us, and we will come collect them for testing. We are continuing to monitor this virus in wild bird populations. It typically doesn’t have much of an impact on the overall populations of waterfowl, but it’s likely that we will have some die now that it’s been confirmed in wild birds in the state.”

The last outbreak of avian flu in the U.S. occurred in 2014–15, when highly pathogenic strains of avian influenza were detected in wild birds of the Pacific, Central and Mississippi flyways. During that outbreak, the virus was detected in two healthy ducks in Utah.
