A Deadly Strain of Bird Flu Has Been Detected in Dairy Cows in Nevada
The new H5N1 strain, also known as bird flu or “bird flu”, was found in herds of dairy products in Nevada.
On Friday, the US Department of Agriculture (USDA) announced that it completed sequencing of the milk genome from Nevada cows and first discovered the genotype D1.1. Until now, all the other dairy herds that have tested a positive result have been checked by the B3.13 genotype.
“The problem with this virus is that it can spread through contaminated clothes, worn out and equipment separated between animals, but birds that carry this disease, published on January 31. “We cannot emphasize how important it is to maintain the cleanliness of the equipment, practice good animal safety methods and strengthen bios safety measures to prevent the spread of the disease.”
According to the announcement, the wildlife services of the US Department of Agriculture, as part of the national strategy for testing milk, are currently considering dairy bunkers to detect the virus before the dairy cow is symptoms, and also tests the wildlife environment for a “better To determine what kind of cunning it is distributed. “This includes” removing non -nor European populations in Churchill, Pershing and Lyon, which are considered “trouble”.
And although the centers of control and prevention of diseases claim that the risk for people is low, the ability of the virus to jump from birds to cattle so easily worries experts.
“We see how the H5N1 virus itself is smarter than all of us,” said Reuters Beth Thompson, a veterinarian of the state of South Dakota. “This modifies itself, so it does not just remain in the bird and wild waterfowl. He raises the house in mammals. ”
This specific strain – D1.1 is also the same strain that was associated with two severe human infections, including a teenager in British Colombia in the fall of 2024 and in the case of Louisiana, where a person died of infection in January.
Nevertheless, Goicoechea said CNN that the cows infected by D1.1, according to the visible, do not have more serious symptoms than that of B3.13 infections.
“We see the same clinical signs,” said Goicoechea, adding that these symptoms include cows that lose their appetite and reduce milk supply. “These are very, very similar signs of what we actually saw last year since it began in Texas and Kansas.”
The bird flu, the US Department of Agriculture noted, was discovered in 957 herds in 16 states since March 2024. According to CDC, bird flu infected 67 people in the United States today. According to CDC, 153 866 301 birds, including a commercial bird, were infected with bird flu. As reported about food and fault, this also greatly influenced the supply of eggs to the United States, while the cost of a dozen large -class eggs A reached $ 4,15 in December 2024, which is 37% more than the price of eggs compared to the year. And it seems that there is no end in sight.
