A new strain of H5N1 avian influenza, known as D1.1, has been detected in dairy cattle herds in Nevada, raising concerns about its potential for human infection. This strain, confirmed in late January, is associated with severe human infections, including fatalities. Additionally, the Centers for Disease Control and Prevention highlighted a possible transmission route between infected cats and humans, indicating the need for close monitoring and further research into the virus's spread and impact on public health. These developments emphasize the ongoing challenges in controlling avian influenza.
The discovery of a new H5N1 strain in Nevada cattle presents a potential challenge for eradication efforts, while the virus's spread between cats and humans raises public health concerns.
H5N1 strain D1.1, recently detected in Nevada dairy cattle, poses significant risks due to its origin in wild birds and potential for human infection.
