Lab-Altered H5N1 Flu More Infectious to Humans than Birds

  • Yum

TweetYumA new study suggests a laboratory-mutated H5N1 avian influenza virus could pose a greater risk to humans than to birds, adding to concerns about the new avian flu strain that has emerged recently in China. Over a year ago, Japanese researchers created a genetically-altered version of the H5N1 avian influenza virus to ‘explore the risk […]

H7N9 bird flu virus capable of airborne transmission
