Avian influenza could quickly spread among humans if it mutates further, European authorities are warning.
“These viruses continue to evolve globally, and with the migration of wild birds, new strains carrying potential mutations for mammalian adaptation could be selected. If avian A(H5N1) influenza viruses acquire the ability to spread efficiently among humans, large‐scale transmission could occur due to the lack of immune defences against H5 viruses in humans,” the European Food Safety Authority said in an April 3 article.
