Bird flu discovered in marine mammals raises human risk.

New Study Warns Avian Influenza Has Mutated for Greater Transmission Between Birds and Marine Mammals, Heightening Human Risk

🦠🌊 The Rise of a New Monster: Bird Flu Spreads Among Marine Mammals

News Picture: Bird Flu Found in Sea Mammals, Upping Risk to Humans

Bird flu has taken a terrifying turn! According to a recent study, the avian influenza virus H5N1 has mutated to spread more easily between birds and marine mammals, posing an increased risk to human health. 🐦🦈🤒

In Argentina, researchers discovered that four sea lions, one fur seal, and a tern, were all infected with the avian flu virus. 🌊 The genetic analysis uncovered that the virus found in these animals were almost identical to a strain previously detected in a human case in Chile, as well as in sea lions in Peru and Chile. This multi-species outbreak indicates that the virus can still infect birds, despite its ability to adapt to marine mammals.

“This confirms that while the virus may have adapted to marine mammals, it still has the ability to infect birds,” explained Agustina Rimondi, a virologist from the National Institute of Agricultural Technology in Argentina. But don’t panic just yet! Although the current variant of H5N1, known as clade, is considered a “new monster,” senior researcher Marcela Uhart assures us that it remains relatively low risk for humans. Phew! 😅

However, Uhart emphasizes the importance of ongoing surveillance to provide early warnings. As long as the virus continues to replicate in mammals, it could potentially become more concerning for humans. So, it’s crucial to keep a vigilant eye on this evolving situation. 👀

The new variant of H5N1 emerged in 2020 during the pandemic, starting with sea bird deaths in Europe and then spreading to South Africa. By 2022, it reached the United States, Canada, Peru, and Chile. And in February 2023, it made its entry into Argentina. From there, it swiftly moved northward, infecting and eventually killing marine mammals and seabirds. 😢

Everywhere it goes, this virus leaves a trail of devastation. A recent study reported a large outbreak in Argentina that wiped out 70% of elephant seal pups during the 2023 breeding season. In surveyed regions of Argentina, mortality rates reached a staggering 96%! 😭

The H5N1 bird flu has been responsible for the deaths of at least 600,000 wild birds and 50,000 mammals, including elephant seals and sea lions in Argentina, Chile, and Peru, as well as thousands of albatrosses in the Falkland Islands. And the concerning thing is, it’s not done yet! The virus is headed southward towards Antarctica, raising concerns about a potential outbreak among penguins and other vulnerable wildlife. 🐧🥶

We must closely monitor the ability of this virus to infect new species, as the consequences can be severe. The study urges continuous surveillance efforts to stay one step ahead of this evolving threat. 😷


Q: Is there a risk of the avian flu virus spreading to humans? A: While the current variant (clade of the H5N1 bird flu is considered low risk for humans, the continued replication of the virus in mammals raises some concerns. However, with proper surveillance and early warning systems in place, the risk can be mitigated.

Q: How can we prevent the spread of the avian flu virus? A: Prevention measures primarily involve rigorous surveillance, especially in areas where the virus has been detected. Additionally, practicing good hygiene, such as washing hands frequently and avoiding close contact with infected animals, can help reduce the risk of transmission.

Q: Can the avian flu virus infect other animal species? A: While the virus primarily affects birds and marine mammals, it is important to monitor its potential to infect new species. This virus has already demonstrated its ability to adapt and infect multiple creatures, so ongoing surveillance is crucial to prevent further outbreaks.

Q: Are there any potential treatments for avian flu in humans? A: Antiviral drugs, such as oseltamivir (Tamiflu), are currently the mainstay of treatment for avian flu in humans. However, it’s important to note that swift identification and early treatment are essential for optimal outcomes. Vaccines are also being developed to offer further protection against this virus.

Q: How does the avian flu virus impact wildlife ecosystems? A: The avian flu virus has had a devastating impact on wildlife ecosystems, causing mass deaths among various species of birds and marine mammals. This not only disrupts the delicate balance of ecosystems but also threatens the survival of vulnerable species. It is crucial to implement effective measures to minimize the spread of this virus and protect biodiversity.
