The H5N1 bird flu virus, which has caused significant outbreaks in dairy cows in the U.S., is showing increased adaptability to spread in mammals. Researchers have found evidence of the virus spreading among elephant seals and other marine mammals in South America. This raises concerns that the virus could eventually transmit from mammal to mammal and potentially pose a threat to humans. Genetic sequencing has identified a particular lineage of the virus that has evolved to spread easily between mammals. This lineage has been linked to outbreaks in multiple countries in South America, marking the first known multinational mammal-to-mammal spread of the virus. Scientists emphasize the need for continued monitoring of the virus in wildlife to understand its potential implications for human health.

A pod of killer whales attacked and sunk a yacht in the Strait of Gibraltar, injuring two people on board. The incident occurred on Sunday morning, and officials believe there were more than 37 orcas involved. There have been approximately 700 orca attacks since 2020, and experts believe the whales may be targeting vessels for sport or feeling threatened. The Strait of Gibraltar is a known hotspot for orca attacks, and officials are urging boaters to be aware of the potential danger.

A highly pathogenic strain of H5N1 bird flu has spread worldwide since 2020, killing millions of poultry and other birds. Now, it’s threatening marine mammals, with devastating outbreaks in elephant seals and sea lions in South America. Experts warn that the virus is adapting to mammals, raising concerns about its potential to spread to humans. The current outbreaks in dairy cows and mink suggest that H5N1 may be on the brink of becoming transmissible among people. Scientists emphasize the need for increased monitoring, international cooperation, and proactive measures to prevent a human pandemic.
