A newly identified strain of H5N1 bird flu<\/strong> has been confirmed in dairy cattle in Nevada<\/strong>, marking the second known spillover of the virus from wild birds to cows<\/strong> in the United States. This latest discovery underscores growing concerns about the disease\u2019s ability to spread between animals and its potential risk to humans.<\/p>\n\n\n\n
The H5N1 virus<\/strong> has already affected over 950 herds across 16 states<\/strong>, with milk samples collected under a USDA surveillance program <\/a>detecting the new D1.1 strain last week<\/strong>. Experts stress that increased testing is essential for tracking the virus and understanding its spread.<\/p>\n\n\n\n
Public health officials are closely monitoring human cases linked to the virus<\/strong>, particularly among individuals who work directly with infected cattle. At least 67 people in the US<\/strong> have been infected with bird flu<\/strong>, most of whom had close contact with dairy animals.<\/p>\n\n\n\n
The D1.1 strain<\/strong> has been linked to two severe human cases<\/strong> in North America<\/strong>:<\/p>\n\n\n\n
Experts warn that continued mutations could increase the virus\u2019s ability to spread between humans. Michael Worobey, an evolutionary biologist at the University of Arizona<\/strong>, emphasised the importance of sharing genetic data quickly, calling it a \u201cvital part of national and global security.\u201d<\/p>\n\n\n\n
Federal officials have announced that genetic sequences of the D1.1 strain<\/strong> will be made publicly available later this week, helping researchers determine whether this spillover event is recent or if the virus has been circulating undetected for months.<\/p>\n","protected":false},"excerpt":{"rendered":"
