There is an alert due to the confirmation of the first case bird flu (HPAI H5N1) in remote areas AntarcticaThe following is an analysis of samples taken by British Antarctic Survey (BAS) staff in seabirds The Brown Skua that is presented is strange symptomassociated with high mortality rates type in the South Georgia Islands.

After sending to great BritainHealth Agency analysis Animals and Phytosanitary, confirmed positive for HPAI H5N1. That disease will be introduced, with great probability, by birds who returned from their migration to South Americawhere they have died for this pathologyaround 500,000 seabirds and 20,000 sea ​​lions only in Chilli And Peru.

Responding to the outbreak H5N1Government Island Sandwich South And Georgia South They remain vigilant to detect more cases, fearing the disease will spread through dense colonies birds And mammals present in the area. Additionally, they maintain the measures in place biosecurity improved in its science and visitor programs, as confirmed by British Antarctic Survey.

Currently, station investigation about bird flu in the Bird Island, South Georgiawhere such cases were identified, has halted most of the field work involving such cases animal handling to implement the measures biosecuritywhich includes intensive cleaning of clothing and field equipment.

As known as bird fluis viral disease very infectious which influences various type birdsLots local as wild. That infection manifests itself in different ways without symptoms or mild to more serious, with symptom including lack of energy or appetite, decreased egg production, breathing problems, and, in severe cases, death.

This disease caused by virus From that family Orthomyxoviridae of Influenza A type. There are many strainssome of them can spread to Manraises concerns public health at the global level.

That sprouts in the poultry can have a large economic impact because mass death and control measures implemented to limit spread from viruslike a sacrifice animal affected and at risk. That transmission usually occurs through direct contact between birds or in between birds and contaminated surfaces, including some strains from virus They can also be transmitted through the air.

It is important to note that, although there have been cases of transmission birds to man relatively rare, few variations virusas H5N1 And H7N9has caused Serious illness and even death in it infected person.

Most of the infection in the man occurs after direct or close contact with infected birds one of contaminated surface with their excretions. However, transmission is ongoing person to person This virus limited and no changes were observed spread efficient between man.

One of the biggest fears expressed by scientisthas to do with the potential impact of the virus H5N1 in fauna isolated from Antarctic regionespecially residents penguin And seal who have never been exposed to this deadly disease disease before.

According to Dr. Meagan Dewar, Network president Antarctica from Health from Wild life and lead author of the report, the alarm sounds about the possibility of “catastrophic reproductive failure” in vulnerable groups fauna this region with “devastating impacts for many people type from wild life” said to Guardian.

In relation to population birds And mammals in Antarctica and surrounding islands, Expert Network Organization in Bird flu from World Organization for Animal Healthwarns of “efficient transmission virus” in the region, home to more than 100 million people birdssix species pinnipeds as seal And walrus and 17 species cetaceansconfirmed CNN.
