A new study has uncovered a terrifying trait in bird flu viruses — they can survive even during high fevers, one of the body’s strongest defenses against infections. Researchers from Cambridge and Glasgow found that a single gene, PB1, gives bird flu the power to keep replicating at temperatures that stop human flu dead in its tracks. Even more alarming, this gene can jump between bird and human flu strains — a phenomenon seen in past deadly pandemics. With bird flu fatality rates in humans exceeding 40% in some cases, experts warn this mutation could fuel the next global outbreak. Watch to understand how this virus is evolving — and why scientists are on high alert.<br />WooGlobe Ref : WGA586572<br />For licensing and to use this video, please email licensing@wooglobe.com
