New A(H5N1) Avian Flu Strain
A new strain of avian flu, A(H5N1), is showing increased airborne spread, raising concerns about public health risks. Identified first in a Texas dairy worker, this strain has infected polecats, minks, and dairy herds across 15 U.S. states. Research by Erasmus University Medical Center found that mutations PB2-E627K and PB2-T271A enhance mammalian transmission, with ferrets as a key model. The virus, belonging to clade 2.3.4.4b, sheds more infectious particles than earlier strains, evolving for airborne spread. Governments, including the UK, are preparing vaccines, stressing the importance of vigilance and global health preparedness.
