The World Health Organization has warned that a newly emerging influenza variant is spreading rapidly across multiple regions, with health officials monitoring a rise in severe disease and hospitalisations as the flu season intensifies.
Speaking in Geneva, Dr Wenqing Zhang, head of global respiratory threats at the WHO, said influenza activity is surging alongside other respiratory viruses. This year, she noted, is marked by the rapid expansion of a new influenza AH3N2 variant known as subclade K, officially classified as J.2.4.1.
