and research teams in the area are taking action to monitor and limit the disease's spread, including putting most animal handling work on hold.Since the current outbreak of H5N1 HPAI began, huge numbers of seabirds have died throughout North and South America, the Atlantic and Pacific Oceans, as well as in the southern part of Africa.
Numerous species of seabirds, penguins, and other birds live in the Antarctic, many of which are not found anywhere else on Earth. These birds are frequently densely populated, and have limited natural immunity to avian influenza due to a lack of historical exposure, making them extremely vulnerable to infection.they were implementing extra measures like protective clothing and masks when working close to seabirds to avoid transmitting the highly contagious virus to wildlife themselves.
Infected birds' droppings, feathers, and respiratory secretions spread avian influenza so the virus could quickly travel from Bird Island to the rest of the Antarctic region, resulting in widespread outbreaks and massive bird deaths.The return of birds from their migration to South America, where there are a large number of HPAI cases, is likely what carried the virus to Bird Island.
Large outbreaks have been reported in both Chile and Peru since HPAI arrived in South America, and it has spread over 6,000 kilometers in as little as three months, following the Pacific coast of South America to its southernmost tip off Tierra del Fuego.in Peru and Chile alone as a result of HPAI H5N1. This virus has recently spread to the Atlantic coast of Argentina, with cases discovered in sea lions all the way from Tierra del Fuego to Buenos Aires.
Although waterfowl, gulls, and shorebirds play a central role in the avian influenza viral cycle in the wild, the virus appears to be easily transmitted between different species of birds.
