Bird flu crisis escalates: Virus spreads to pets and wildlife across 31 US states

Bird flu, a highly contagious strain of avian influenza, has shown alarming zoonotic potential in recent weeks, spreading rapidly across the United States and infecting four humans to date. Originally confined to farmed poultry and wild birds, the virus has now been detected in cats in 31 states, with some cases also reported in dogs. This raises significant concerns for both human and animal health, particularly among pet owners.

The virus’s reach extends to 31 states, and as reported by USA Today, it has infected various animals, including mice, foxes, mountain lions, alpacas, and cows in 12 states. Over the past few months, the virus has swiftly spread among dairy cows, impacting over 90 herds despite earlier expert reassurances that dairy products would remain unaffected.

In addition to farm animals, the H5N1 virus has also affected dairy workers, with three laborers contracting the infection. The increasing concern stems from the occasional cases reported in domestic pets, specifically dogs and cats. Since March 1, over 21 domestic cats in nine states have been diagnosed with the illness. Researchers have long known that cats can contract avian influenza, with Kristen Coleman from the University of Maryland noting that domestic cats are particularly susceptible to H5N1, as reported by the New York Times.

Among the infected cats are feral, barn, and domestic cats. Although fewer cases have been reported in dogs, the threat remains. The H5N1 strain of bird flu, which emerged in 2020, has spread globally, causing severe illness and often death in affected animals. While the Centers for Disease Control and Prevention (CDC) states that the risk to humans is very low, there is a small chance of human infection if pets are infected. Experts caution that the virus could be transmitted through a cat’s saliva, feces, or other bodily fluids.
