H5N1 bird flu virus causing unprecedented global outbreaks

A study published in Nature reveals that the H5N1 bird flu virus has caused unprecedented outbreaks in wild bird species across five continents since November 2021. The virus has become more persistent in wild bird populations, spreading to new regions and affecting marine and land mammals. The virus has shifted from China to Europe and northern Africa, posing an environmental disaster. Researchers urge sustained vaccination to eliminate the virus. Gene editing shows promise in breeding chickens resistant to bird flu.
