Dead pups spread on an extended beach. Adults abandoned the breeding area. There are only carcasses in a coast that should have congregated thousands of reproductive females and males.
Newswise — New York, January 15, 2024 – The Wildlife Conservation Society is issuing the following statement about H5N1 Avian Influenza due to ongoing wildlife die-offs across the world:
Said Dr. Chris Walzer, WCS Executive Director of Health:
“With the frightening die-off of animals across the globe due to avian influenza, WCS is calling for governments internationally to treat this growing crisis with the urgency it demands. As we continue to monitor the death of innumerable species and track the movement of highly pathogenic avian influenza (HPAI) into mammal populations, we must strengthen the focus on integrating the surveillance of emerging influenza clades in wild birds and mammals to support critical vaccine libraries.
“H5N1 now presents an existential threat to the world’s biodiversity. It has infected over 150 wild and domestic avian species around the globe as well as a dozens of mammalian species. The bird flu outbreak is the worst globally and also in U.S. history, with hundreds-of-million birds dead since it first turned up in domestic waterfowl in China in 1996. Bird flu is highly transmissible, spread through droplet and feces-borne infections, and exacerbated by climate-change-altering migration schedules for birds and its repeated re-circulation in domestic poultry.
“Globally, HPAI H5N1 has now infected many mammals—including foxes, pumas, skunks, and both black and brown bears in North America. Some 700 endangered Caspian seals died from HPAI near Dagestan in 2023. Additionally, outbreaks in mink farms in Spain and Finland that serve as potential mixing vessels for reassortment have also been documented. HPAI H5N1 has arrived in Latin America with devastating consequences, afflicting multiple countries that include WCS land- and seascapes in Peru, Chile, Uruguay, Ecuador, and Argentina.
“More than 95 percent of the Southern elephant seal (Mirounga leonina) pups born along 300 km of the Patagonia coastline died at the end of 2023. It’s the first report of massive elephant seal mortality in the area from any cause in the last half century. The sight of elephant seals found dead or dying along the breeding beaches can only be described as apocalyptic. This 2023 die-off contrasts starkly with the 18,000 pups born and successfully weaned in 2022.
“As the virus continues to spread through mammal populations, the World Health Organization (WHO) has called on public health officials to prepare for a potential spillover of H5N1 to people. The "R naught" value—or the number of people infected by a single infected person—for COVID initially ranged from 1.5 to 7. For H5N1 among birds, it is around 100. It is imperative that we take a collaborative One Health approach to identifying emerging strains of bird flu across the globe to support the development of specific and universal vaccines that can quickly treat infection in people to prevent another pandemic.
“The cost of inaction is already causing major devastation to wildlife. As we work to help affected populations recover, we must remain vigilant against the spread of this deadly pathogen to people before it’s too late.
Background
Wildlife Conservation Society Health Program
In the last few decades, it has become increasingly evident that conservation, our own health, and the health of wild and domestic animals are all inextricably linked. A single pathogen can wipe out the last populations of an endangered species and, in turn, threaten the stability of local human populations. Thus there is an urgent need to simultaneously address the health of people, animals and the environment recognizing that disease poses challenges to both conservation of the planet's biodiversity and efforts to improve the quality of human life.
Additional Background: Global leaders in wildlife and human health issued 10 principles – The Berlin Principles – with an urgent call to governments, academia, and civil society that all sectors need to break down barriers to ensure a united effort to prevent the emergence or resurgence of diseases that threaten humans, wildlife, and livestock.
Wildlife Conservation Society (WCS)
WCS combines the power of its zoos and an aquarium in New York City and a Global Conservation Program in more than 50 countries to achieve its mission to save wildlife and wild places. WCS runs the world’s largest conservation field program, protecting more than 50 percent of Earth’s known biodiversity; in partnership with governments, Indigenous People, Local Communities, and the private sector. It’s four zoos and aquarium (the Bronx Zoo, Central Park Zoo, Queens Zoo, Prospect Park Zoo, and the New York Aquarium ) welcomes more than 3.5 million visitors each year, inspiring generations to care for nature. Founded in 1895 as the New York Zoological Society, the organization is led (as of June 1, 2023) by President and CEO Monica P. Medina. Visit: newsroom.wcs.org. Follow: @WCSNewsroom.
