Dairy cattle in Nevada have been infected with a new type of bird flu, different from the one that has spread in U.S. herds since last year. The virus, known as Type A H5N1, has spilled over from wild birds into cattle at least twice, raising concerns about wider spread and control. The new version, D1.1, was confirmed in Nevada cattle, highlighting the importance of testing and surveillance. Experts emphasize the need for prompt sharing of information to prevent a potential pandemic that could have significant impacts on public health and national security.
