Dairy cattle in Nevada are affected with a new type Bird Flu Agriculture officials said on Wednesday that it was different from the version that had spread to the US herd since last year.
This shows that separate forms of the virus, known as Type A H5N1, were slipped into cattle at least twice from wild birds. Experts say it raises new questions about the widespread spread of infections and the difficulty of controlling infections between animals and people working with them.
“I have always thought that a cow transmission from birds is a very rare event. It may not seem that, “said Richard Webbie, an influenza expert at St. Jod Children’s Research Hospital.
Scientists said that a version of the H5N1 Bird Flow virus was known as B3.13, which was confirmed in March after being introduced to livestock at the end of 2023. It has affected more than 950 flocks in 16 states. According to the USDA, the new version of Nevada cattle was confirmed in New Delhi on Friday. Its address was found as part of a monitoring program launched in December.
“Now we know why it is really important to continue to test and test,” said Angela Rasmussen, a virus expert from the University of Saskichovan in Canada, “said Angela Rasmussen, first assisted in the identification of Splore.
The D1.1 version of the virus was of the type that was associated with the first American death associated with Bird Flu and a serious illness in Canada. A person in Louisiana Passed away in January After contact with the wild and backyard birds after developing severe breath symptoms. In British Columbia, A teenage girl was admitted to the hospital for months in which a virus was traced to poultry.
According to US centers for Disease Control and Prevention, at least 67 people in the United States have been affected by the bird flu, mostly those who work with dairy or livestock.
USDA officials said they would publish other information about the genetic setting and the new form of viruses this weekend. Scientists said it would be the key to understand whether Spalore was a recent event or the virus has been circulating widely, probably.
“If it mastered cattle a few months ago, it is a few months long to detect,” said Michael Verobi, a evolutionary biologist at the University of Arizona. Cattle
He added that it is important for federal officials to immediately share information about a virus that has the ability to mobilize a pandemic disease that “seems like a walk in the park. “
“It is an important part of national security, global security, people’s welfare, people’s welfare, animals and business in the United States,” Verobi added.
