Experts warn: bird flu "fast -size" virus is close to human injury

Experts have warned that the “H5N1” virus, which is behind the spread of bird flu around the world, is changing quickly with increasing calls to pollinate poultry, pointing out that the increasing number of cases between breast animals, despite the decline in humans, is “worrying.” happened, it made more able to cause infection, “said Richard Wipi, the world of virus and the director of the World Health Organization for Bird Diseases. A study published this week in the “Nature Communications” magazine, and showed that the virus developed quickly with the spread of Europe to North America. He explained that the researchers hit a mongoose of one of the new breeding bird flu and found a ‘large’ amount of virus in his brain, which indicates that the new strains are more dangerous. Although he indicated that the danger is still low for humans, he noted that the virus is “not stuck, but rather develops, and it increases the risk of obtaining the virus, and coincidentally genetic features that bring him closer to being a human virus.” According to Wipi, a “worrying meaning” and the cases of human infection, which sometimes led to death, are still rare, usually after they are now dealing with infected birds, but the discovery of the disease in an increasing number of mammals, including new types, is a “very worrying sign”. Wipi said bird viruses are “associated with different receptors on the host cell compared to human viruses,” explains that it will “take” two or 3 minor mutations in one of the virus proteins, so it becomes more adaptable to humans. ” Last week, Chile announced that about 9,000 lion animals, penguins, water foxes, sea pigs and dolphins have died of bird flu on the northern coast since early 2023. Most of them are believed to be infected with the virus by eating infected birds. In this regard, the president of the World Health Organization, Tedros Adhanum Gybrysus, warned in February that “cases of the recent transmission of the virus in mammals should be carefully monitored.” Ian Brown, head of the British viruses of viruses, said there is no “clear evidence of the ability of this virus to stay in mammals”, emphasizing that the virus has developed to “multiply in birds”, it is still “inactive with humans”. Vaccination and tipping see that one of the ways to reduce the number of bird flu and reduce the human risk is to vaccinate poultry. He pointed out that some countries, including China, Egypt and Vietnam, have arranged these vaccination campaigns, but many other countries hesitate for fear of imposing possible restrictions on imports and crossing infected birds through the gaps in the chain. Last April, the United States started testing many vaccines for its possible use in birds, and France recently indicated that it hopes to start the fall with poultry vaccination. But Christine Midolmis, head of veterinarians in the UK, said the vaccination of poultry “is not a magical solution because the virus is constantly changing,” and adds that the reluctant countries should consider it at a greater rate. Meanwhile, the Director General of the World Animal Organization, Monic Elite, has seen that the issue of immunization of poultry should be one of the options, and note that “everyone now knows that the epidemic is not just a fantasy but can be a reality.” Also read:
