The second strain of the bird flour found in Nevada dairy cows

The US Department of Agriculture (USDA) said dairy products in Nevada have been infected with the new strain of the bird flu virus.

The strain found in the Nevada cattle raises new questions about spreading the Avian influenza virus into a dairy cow, which many assumed that the virus started from the birds of Texas.

The new version of the virus matches the strain currently found in the wild bird and domestic poultry, as well as in serious human cases – a Louisiana died in January and a Canadian teenager who was hospitalized for more than two months and died.

The virus has never been seen in cattle before, the Nevada cow denies the possibility of catching it from another infected animal.

The evolutionary biologist at the University of Arizona Michael Warobby said that the initial hope was that the rare transformation allowed to jump from the birds and settle in cattle.

“Now, we know this is not true,” Warobi said. “This means we are probably playing WAC-A-mole with it just jumping over and over again and hoping to use the tools that we hope to get rid of it [the virus] May not work as well. ”

The second known example of cattle infected after the virus jumps from wild birds, which experts say that the cattle are sensitive to the other H5N1 viruses, not just the specified sub type that starts in Texas, and then 16550 dairy beasts are infected with States, USDA, USDA. Accordingly

“It is not clear now how extensive it is. But now we should test the expansion of D1 among wild and domestic birds, to see if the H5-positive poultry is in the premises aggressively, to see if this incident is beyond Nevada, “Louis Monkla,” Louis, “Louis,” Louis, ” Monkla, Louis Monkla, a pathobiologist, Pennsylvania, said in an email.

However, since many states were not tested very thoroughly, the farmers were reluctant to test their livestock, it is possible that the virus spread from the bird to the cattle could not be detected.

The USDA has said that the identification of this version of the virus was confirmed on January 31st. After it is found in raw milk collected from a silo as part of the National Milk Examination Strategy, which started in 2024.

Federal officials have maintained that ordinary people have low risk and experts say no change is seen on the basis of new inquiries.

However, Monkla also mentions that the humanitarian cases involved in the contact of infected cattle have been lightened, while on the other hand there has been at least one serious event after the wild bird or the back of the backyard.

“Although it is soon to make a decision about it, it is related. We still do not know if these viruses are better in infected people. But if they are, then the identity of dairy cattle can increase the risk of exposure to human beings, “said Mankala.

Warobi said that he was leading a group of scientists to try to find out how long he was being broadcast in cattle before searching for livestock. However, he said that this search reduced the possibility that the virus could be completely eliminated from the cattle, as it had many different versions of the virus that jumped from birds to cattle.

Dairy cattle against the bird flu cannot hold on to the immunity D.11 Genotype.

“Cattle also may also need to start anew in increasing the resistance of this strain,” Warobi said.

There is also concern about potential vaccines and they can be so precise with the first variant that they will not help block new variation infections.

There is currently no licensed H5N1 vaccine for cows, but some are in development.
