Bird flu strongly strikes the United States. Now, migratory birds fly north

Bird flu at a dangerous point in the United States: It was approximately 167 million birds Affected By H5N1 dynasty since 2022, 70 infected people. Now, birds fly on our way to the spring deportation season.

Gos Snow near Montreal, a large corneal owl in southwest Ontario, Canada’s goat in Langley, BC – these are just some of the wild birds that have recently experienced H5N1 in Canada. But scientists are preparing for more, and they intensify their efforts to monitor and reduce the virus this season.

This winter has witnessed more H5N1 outbreaks than usual, said Dr. Monon Richot, the veterinarian of the Canadian Food Inspection Agency (CFIA) in St. Hyssineth, Qio.

“Now that the birds have returned north to migrate, we don’t really know what will happen to us. Will birds remain infected?

In addition to the anxiety of scientists: it was another breed of bird flu, H7N9, I mentioned On the Mississippi Poultry Farm, the United States – the first since 2017. While it is not the dominant type of bird flu that currently performs tours in the United States, H7N9 has a much higher death rate than H5N1, killing nearly 40 percent of people with her discovery in 2013. He said State authorities.

One mutation away

H5N1 also crossed the species, and they were adapted to mammal hosts. Animals like seals, cats and dogs have died after mixing with wild birds, or eating raw pet food.

Dairy cows in the United States are sick in large numbers, as 989 of its herds were affected by 17 states, According to the centers of control and prevention of diseases.

Bird flu does not seem easily unacceptable among people, at the present time. But the H5N1 breed circulated in the cows in the United States is only one boom away from being more transmitted among humans, as suggested study It was recently published in the magazine of Science Science, which was reviewed by the peer.

And when human beings, the virus can be fatal. In January, one of the elderly people in Louisiana became the first H5N1 human death in the United States

The H5N1 case known in Canada was confirmed two months ago, in November: A teenager in British Colombia was transferred to the hospital for two months. We still do not know how it was injured.

Either way, the genetic analysis suggested The virus had mutated To become Attractive attachment To the cells in the upper respiratory system.

All this has scientists and doctors at maximum alert.

“In fully, one case of bird influenza is very related because we do not want the virus to adapt to humans,” said Dr. Danota Scoreonski, an epidemic scientist at the Center for Disease Control (BCCDC.

“We are all responsible for closing this as soon as it can be contained. This is a global effort. We are communicating globally with the United States, with the United Kingdom, with wherever we can to ensure that we get the best possible knowledge.”

Withdrawal from, stood to rehabilitate employees

Ian Brown, a leading bird flu expert at the UK Institute of Perbright, says the extent to which the disease changes in the United States at the present time, it is important for the American authorities to continue to communicate with other countries and the World Health Organization (WHO)

But the Trump administration attracts the United States from. It also interrupts funding and jobs in major agencies such as the National Institutes of Health.

“We know it is a sensitive situation. We know some of our colleagues, they may be at risk of not having a job,” said Brown.

He says he is in the early days, but he is afraid that there will be to reduce information between American scientists and international counterparts.

“Early signs are that the interaction that we used to exist, successfully for many years, may be at risk now.”

There was already a mistake.

Its Ministry of Agriculture has She stood to rehabilitate Employees who work to respond to bird influenza, after they were accidentally shot during their rapid cleansing of the federal workforce, regarding the recommendations of the Ministry of Governmental efficiency in Elon Musk. They faced a problem in restoring them, Politico mentioned.

The World Health Organization has already seen an impact on bird flu control discounts, onIdentification card General Manager d. Tedros Adhanom Ghebreyesus on Monday.

Does the United States speak with Canada on bird flu?

Fortunately, the United States is due to Canada’s calls for bird flu, especially among those who work with affected poultry or dairy cattle, says Dr. Teresa Tam, the chief public health employee in Canada.

Tam said: “I think public health at every level is trying to be very awake about cases in these different populations and share information continuously,” Tam said.

Canada depends on the United States to effectively reduce the virus. On the side of animal health, for example, US and Canadian officials work together to monitor bird airlines and monitor wild and home birds, exchange disturbing mutations, as well as the approximate sites of infected birds.

At the boycott level, also, the difference in British Columbia continues closely with their counterparts in states such as Washington, Oregon and Alaska.

“I think one of the things that help us is the relationships that we have, and personal relationships.”

Canada is also closely watched on our dairy cows: CFIA Sampling tests From the next raw milk in the treatment of plants. To date, all negative samples have returned, as of February 28.

Learning from Covid-19

But both Tam and Henry assert: It is important to mess with the control of Canada and prepare, especially in the event of changing the virus and becomes more transmitted among humans, which may raise a pandemic.

These efforts include “increased monitoring and vigilance, laboratory tests, and ensuring an investigation into any human condition,” said TAM.

BCCDC scientists are among many who are already doing some of this preparatory work.

“Through the epidemic, we learned a lot about the tools that public health can use to make its decisions,” said Linda Huang, Director of Public Health Laboratory.

BCCDC monitors mutations that can make H5N1 more human air -conditioning, develop antibody tests to monitor human exposure, and research how to transport bird flu.

It is all the information that may be decisive for decision makers if the virus becomes more transmitted.

Henry says she is confident – even if there are temporary silences from their American counterparts – that Canadian monitoring is strong enough to closely monitor the bird flu.
