Nearly 600 sea lions die due to bird flu outbreak in Peru

Peru reported the death of 585 sea lions and 55,000 wild birds due to the H5N1 bird flu virus in recent weeks. Following the discovery of 55,000 dead birds in eight protected coastal areas, rangers found the bird flu that killed them had also claimed 585 sea lions in seven protected marine areas, the Sernanp natural areas protection agency said.

Cause of The Incident:

The dead birds included pelicans, various types of gulls, and penguins, the Sernanp said in a statement. Laboratory tests also confirmed the presence of H5N1 in the dead sea lions, prompting the authorities to announce a “biological vigilance protocol.”

For its part, Peru’s National Forest and Wildlife Service (SERFOR) urged people and their pets to avoid contact with sea lions and sea birds on the beach.

The Timeline of these outbreaks:

• Since late 2021, Europe has been gripped by its worst-ever outbreak of bird flu, while North and South America are also experiencing severe outbreaks.
• In November, the country declared a 180-day health alert after finding three cases of highly contagious H5N1 in pelicans.
• According to the SENASA agricultural health agency, the disease is transmitted by migratory birds from North America.
• The reports add to a growing number of detections in mammals, including recent reports from the United Kingdom and H5N1 in farmed minks in Spain. The United States has so far reported 110 detections in mammal species, reported University of Minnesota’s CIDRAP report.
• The H5N1 clade circulating in birds, poultry, and an increasing number of mammals has a mutation that makes the virus more recognizable by mammalian airway cells.
• The World Organization for Animal Health (WOAH) raised concerns about not only the spread of the highly pathogenic avian flu to new countries in Central and South America, but also the speed of the spread over a 4-month period, with occasional spillovers to humans and mammals. The most recent human case was reported in a 9-year-old girl from Ecuador.
• Newly affected countries include Bolivia, Colombia, Costa Rica, Ecuador, Honduras, Panama, Peru, and Venezuela. Chile reported its first high-path outbreaks in 20 years, added CIDRAP report.

About Sea Lions or Seals or Pinnipeds:

• Pinnipeds, commonly known as seals, are a widely distributed and diverse clade of carnivorous, fin-footed, semiaquatic marine mammals.
• They comprise the extant families Odobenidae (whose only living member is the walrus), Otariidae, including numerous kinds of fur seal and sea lion; and the earless seals, known as true seals or Phocidae.
• There are 33 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. Pinnipeds belong to the order Carnivora and their closest living relatives are bears and the superfamily of musteloids (weasels, raccoons, skunks, and red pandas), having diverged about 50 million years ago.
