What is H5N1 and how is it affecting marine life?

H5N1 is a highly pathogenic avian influenza virus that has expanded its reach from birds to marine life, causing significant mortality among seals and sea lions.

Where have the recent outbreaks of avian flu in marine mammals occurred?

Recent devastating outbreaks have been observed in the coastal regions of South America, leading to the deaths of tens of thousands of marine mammals.

How does avian flu transmit among marine mammals?

Transmission is believed to occur through contact with infected seabirds or their carcasses, and there is growing concern that the virus may be adapting to transmit between mammals.

Avian Flu Invades Oceans, Threatens Marine Life

Highly pathogenic avian influenza (H5N1), a virus long known in birds, has now significantly impacted global oceans and marine life. Recent outbreaks along South America's coast have resulted in the deaths of tens of thousands of seals and sea lions.

Researchers from The Royal Society are studying the transmission of H5N1 within pinnipeds, noting a substantial shift in the virus's behavior. This spread among marine mammals heightens ecological risks, with growing concerns that entire populations could be affected if the virus continues its unchecked proliferation.
