The second version of the bird flu in the US now infects the cow

Bird flu, as the name implies, targets and infects birds around the world, with places like the most difficult US. The resulting consequences of the H5 virus forced US farmers and wildlife experts to put 166 million chickens, affecting the cost of a day, such as eggs and chickens sold in grocery stores. The virus that causes many North America to become ill is now found in new species. Make panic, such as Reef of Death, causing some panic fishermen in Walesin the UK

Virologists have found that viral variants, which have mutated and are now common in other hosts, also appear in cows in Nevada. The new variant of the virus, H5N1, is now detected in dairy cows, spreading bird flu to cows. For about a year, the new H5N1 variant called B3.13 has had a significant impact on dairy cows in the United States. Nearly 1,000 livestock in 16 states have been tested positively for H5N1.

This second bird flu outbreak takes place throughout the United States

There are some severe cases for people infected with this new variant

Epidemiologist of veterinarian and environment Meghan Davis of Johns Hopkins Bloomberg School of Public Health said,

“What [experts] Concerned is that it can show another free overflow event into dairy cows,“

However, he stated that the risk of serious illness from H5N1 is still low for most people. This general risk increases, unlike Risks to elephants and other African species, due to an increase in illegal hunting. But with this a batch of bold anti-global womenThere is hope for those who are threatened. On the other hand, the risk of virus spreading to more mammals is, of course, concerns for public health.

According to the US Centers for Disease Control and Prevention, cattle infection has been reported to have led to 40 of the 67 human cases certified by the highly contagious bird influenza in the United States since the beginning of 2024. No one caused by human transmission to humans.

Nevada has now reported 11 outbreaks, most since December 2024. USDA reports a new version of the Nevada outbreak in early February, involving birds and cows. As of April 9, 2025, 17 countries have confirmed the infected cattle. Microbiological damage is a genotype difference between the two strains, but the result is the same.

The second bird flu infection spreads between the cows

The H5N1 virus spreads or transmitted through direct contact, body fluids, and contaminated surfaces

The spread of the virus is still unknown; However, some theories have been suggested. Although the origin of the infection is predictable, research is underway to determine how the virus mutation will develop and identify new methods for combating it.

The first case of infection is most likely due to contaminated birds that come in contact with one of the cows. The same bird flu that leads to the death of this one -month chick was mutated into variant D1.1 and could not be detected, but it was observed most likely last year. Delivery can then be a combination of direct and indirect routes.

Like The infectious bird flu virus, which also spreads in the United States, a dozen Canadian geese were found dead and tested positively for it. This delivery route includes the relationship of service from contaminated milk equipment. Other direct routes include the movement of cows from one farm to another and potentially contaminated or fomites. The virus has been detected at a high level in infected cow’s milk.

Just like a study of this zombie virus, Many broad studies are ongoing for a deeper understanding. A study conducted in July 2024 produced the following findings.

In other words, they have found the virus in the milk itself, but we do not yet know if they can still be sent to others through milk. The study continues, but the symptoms of the symptoms of the disease have also been reported after consuming milk from infected cows. There is no evidence to suggest that the virus can be transmitted through the use of meat. This means that if cows cannot continue to produce milk, it is possible that milk can still be sold to help farmers receive some of their losses.

The effect of the second bird flu does not look good for US consumers

The effects of US food and agriculture supply continuously, but do not look good for consumers

Although the H5 outbreak has affected egg production and significant price, the effect of H5N1 on Milk production And the price has been relatively small, without the extensive change seen in the dairy industry or on the shelves.

Dairy farmers face economic losses due to the decline in milk production in infected livestock. Studies show that milk loss is about 240 gallons (900 kg) per cow within 60 days after the outbreak. Combined with death and removal of the herd, the total cost of an outbreak is estimated at $737,500 During the observation period.

In further news, the US Department of Agriculture (USDA) Animal and plant health checking services (Apos) confirmed two more cases in dairy cattle from Idaho, raising the number of countries to 985. Idaho has now reported three tracking over the past few weeks. It is possible, although it is not possible, it has been captured early enough that if the infected cattle are emptied, we may see it not spread.

However, if the variation of the milk virus coincides with the chicken outbreak, it will see hundreds of millions of chickens, the cost of milk, cheese, and related products can increase rapidly.

The silver lining is that the effect of the second bird flu on wildlife is low

Although the economic and agricultural effects are not promising, the impact of low wildlife

With the low rate of contact between dairy cows and wildlife, the likelihood of this infection spreading into the wild is low. Cows have a very different genetic makeup, and very few are known to have been found in other mammals such as deer, bears, or foxes. There are several cases that are certified by cats and domestic dogs.

The species that has been affected

• Dairy cows (now) in thousands

• In people (67 certified cases)

• At deer and other wild animals (less than a dozen)

• Dogs and domestic cats (though symptoms are rare)

In general, the threat to wildlife is smaller than the effects of a wallet, as consumer costs threaten to increase in response, especially if the virus continues to spread and is not carried under the heel soon.
