New H5N1 Bird Flu Strain from Texas Worker Shows 100% Lethality in Lab Tests
TL;DR Summary
A study led by Dr. Yoshihiro Kawaoka at the University of Wisconsin-Madison found that an H5N1 virus from an infected farm worker could transmit through airborne droplets and was lethal in mice and ferrets, highlighting the risks of the current H5N1 outbreak. The virus, which efficiently infected human lung cells, contained a mutation promoting replication in mammals. While the CDC considers the public at low risk, the findings underscore the need for continued monitoring of H5N1 viruses in cattle and humans to prevent potential human transmission.
