A study reveals the first known transnational spread of highly pathogenic H5N1 avian influenza among mammals, specifically elephant seals in Argentina, marking a significant adaptation of the virus to mammal-to-mammal transmission. This development raises concerns about potential impacts on human health, wildlife, and livestock, as the virus evolves into separate avian and marine mammal clades.
A new study reveals that the bird flu virus H5N1 has mutated to spread among sea mammals, causing massive die-offs of elephant seals in South America. This development raises concerns about potential large-scale infections in other mammals, including humans. The virus is also linked to an ongoing outbreak among dairy cows in the U.S. and has been detected in mink on a fur farm in Spain. The study, which has not yet been peer-reviewed, provides the first genetic and epidemiological evidence of mammal-to-mammal transmission of the virus.
