The COVID-19 pandemic in Antarctica is part of the worldwide pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to its remoteness and sparse population, Antarctica was the last continent to have confirmed cases of COVID-19 and was one of the last regions of the world affected directly by the pandemic. [1] [2] [3] The first cases were reported in December 2020, almost a year after the first cases of COVID-19 were detected in China. At least 36 people are confirmed to have been infected. [4] Even before the first cases on the continent were reported, human activity in Antarctica was indirectly impacted.
On 12 January 2020, the World Health Organization (WHO) confirmed that a novel coronavirus was the cause of a respiratory illness in a cluster of people in Wuhan, Hubei, China, which was reported to the WHO on 31 December 2019. [5] [6]
The case fatality ratio for COVID-19 has been much lower than SARS of 2003, [7] [8] but the transmission has been significantly greater, with a significant total death toll. [9] [7]
People coming to Antarctica research stations have to undergo isolation and COVID-19 screening. [1] The Antarctica research stations of Australia, Norway and Germany have respirators and coronavirus tests; it remains unconfirmed whether the research stations of the U.S. and Britain have them. [1] The British Antarctic Survey implemented precautionary measures. [10] The Argentine Antarctica territories had taken measures at its six permanent bases to prevent the spread of COVID-19 to the territory before the arrival of the virus. [11]
The impact of the COVID-19 pandemic on travel caused complications with evacuating British Antarctic Survey personnel from the continent. [12]
As of 14 April 2020 [update] , bases in Antarctica contain only skeleton crews, visitors have been limited, and scientific research has been impacted. [13] Several conferences on the topic of Antarctica that had been planned for mid-2020 were cancelled due to the pandemic. [14]
In April 2020, a cruise ship headed for Antarctica had almost sixty percent of its passengers test positive for COVID-19. The cruise stopped in Uruguay, where the passengers were allowed to disembark. [15] [16] [17]
The first official cases were announced on 21 December 2020 by the government of Chile. At least 36 people, including 10 civilians and 26 officers of the Chilean Army and Chilean Navy, were confirmed as positive for COVID-19 after contracting the virus on the Base General Bernardo O'Higgins Riquelme (in continental Antarctica), where they were doing scheduled maintenance work for the base. The people developed symptoms for COVID-19 aboard the Sargento Aldea ship, and most of the cases were treated after arriving to their destinations in Punta Arenas and Talcahuano. [4] [18] [19] [20]
On 14 December 2021, a positive case was detected at the Belgian research station Princesse Elisabeth in Queen Maud Land. Further tests revealed two more cases that were subsequently evacuated on 23 December. 11 of the 30 [21] people present at the station were tested positive. [22]
On 12 January 2022, 13 positive cases were detected at Esperanza Base in Argentine Antarctica. Further tests detected 11 more cases, totaling 24 positive cases. [23]
On 13 September 2022, one positive case was detected at Davis Station in Australian Antarctic Territory. [24] First unspecified case detected at port in Hobart on 10 January 2022. [25]
The first confirmed case at McMurdo Station in Ross Dependency was detected in August 2022. By November, 10% of the population of Station's population was confirmed to be infected. As of February 2023, a total of 175 positive cases have been detected. [26] [27] Covid also reached Amundsen-Scott South Pole Station and WAIS Divide. [28] [29]
On 8 November 2022, 20 positive cases were detected at Dumont d'Urville Station in Adélie Land. 20 of the 21 people present at the station were tested positive. [30]
Covid reached New Zealand's Scott Base, located several miles from McMurdo Station, in February of 2023. [31]
On 18 March 2021, the Chilean Air Force announced they inoculated 49 members of their staff in Antarctica, being the first country to start vaccinating against COVID-19 in the continent.[ citation needed ]
On 7 October 2021, Astra-Zeneca vaccines arrived in Antarctica to vaccinate 23 members of staff that are working for the British Antarctic Survey in the Rothera base. [32] [33]
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD.
The climate of Antarctica is the coldest on Earth. The continent is also extremely dry, averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the continent, because of the katabatic winds. Most of Antarctica has an ice-cap climate with very cold, generally extremely dry weather.
Esperanza Base is a permanent, all-year-round Argentine research station in Hope Bay, Trinity Peninsula. It is one of only two civilian settlements in Antarctica. The base's motto is Permanencia, un acto de sacrificio.
Base General Bernardo O'Higgins Riquelme, also Base Libertador General Bernardo O'Higgins Riquelme, or shortly Bernardo O'Higgins, named after Bernardo O'Higgins, is a permanently staffed Chilean research station in Antarctica and the capital of Antártica Commune. It lies at an elevation of 13 m, about 30 km south-west of Prime Head, the northernmost point of the Antarctic Peninsula, at Cape Legoupil.
Argentine Antarctica is an area of Antarctica claimed by Argentina as part of its national territory. It consists of the Antarctic Peninsula and a triangular section extending to the South Pole, delimited by the 25° West and 74° West meridians and the 60° South parallel. This region overlaps British and Chilean claims in Antarctica. Argentina's Antarctic claim is based on its continued presence at a base on Laurie Island in the South Orkney Islands since 1904, and the area's proximity to the South American continent. Argentina's claim is subject to the Antarctic Treaty. Administratively, Argentine Antarctica is a department of the province of Tierra del Fuego, Antarctica, and South Atlantic Islands. The provincial authorities are based in Ushuaia. Despite the claim to this Antarctic area, Argentinean authority extends no further than the nation's bases.
Colonization of Antarctica refers to establishment of civilian settlements in Antarctica having humans, including families, living on the continent of Antarctica. Currently, the continent hosts only two civilian settlements, the Argentinian-administered Esperanza Base and Chilean-administered Villa Las Estrellas, as well as about 70 scientific and military bases with a transient population of scientists and support staff. Antarctica is the only continent on Earth without indigenous human inhabitants, despite its proximity to Argentina and Chile at the Antarctic Peninsula.
Multiple governments have set up permanent research stations in Antarctica and these bases are widely distributed. Unlike the drifting ice stations set up in the Arctic, the research stations of the Antarctic are constructed either on rock or on ice that is fixed in place.
Base Presidente Eduardo Frei Montalva is the most important Antarctic base of Chile. It is located at Fildes Peninsula, an ice-free area, in front of Fildes Bay, west of King George Island, South Shetland Islands. Situated alongside the Escudero Station and only 200 metres (660 ft) from the Russian Bellingshausen Station, it is at an altitude of 10 metres (33 ft) above sea-level. The base is located in the Chilean commune of Antártica, which is the Antarctic territory claimed by Chile.
The Chilean Antarctic Territory or Chilean Antarctica is the territory in Antarctica claimed by Chile. The Chilean Antarctic Territory ranges from 53° West to 90° West and from the South Pole to the 60° South parallel, partially overlapping the Argentine and British Antarctic claims. It is administered by the Cabo de Hornos municipality in the South American mainland.
Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of 10 March 2023, the pandemic had caused more than 676 million cases and 6.88 million confirmed deaths, making it one of the deadliest in history.
This is a general overview and status of places affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus which causes coronavirus disease 2019 (COVID-19) and is responsible for the COVID-19 pandemic. The first human cases of COVID-19 were identified in Wuhan, the capital of the province of Hubei in China in December 2019.
The worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 severely affected Chile. The virus was confirmed to have reached Chile on 3 March 2020. Initial cases had been imported from Southeast Asia and Europe, and expanded into a large number of untraceable infections, placing the country within phase 4 of the pandemic as defined by the World Health Organization, with over 1,000 confirmed cases by 25 March 2020.
The COVID-19 pandemic was confirmed to have spread to Africa on 14 February 2020, with the first confirmed case announced in Egypt. The first confirmed case in sub-Saharan Africa was announced in Nigeria at the end of February 2020. Within three months, the virus had spread throughout the continent, as Lesotho, the last African sovereign state to have remained free of the virus, reported a case on 13 May 2020. By 26 May, it appeared that most African countries were experiencing community transmission, although testing capacity was limited. Most of the identified imported cases arrived from Europe and the United States rather than from China where the virus originated.
The COVID-19 pandemic was confirmed to have reached Oceania on 25 January 2020 with the first confirmed case reported in Melbourne, Australia. The virus has spread to all sovereign states and territories in the region. Australia and New Zealand were praised for their handling of the pandemic in comparison to other Western nations, with New Zealand and each state in Australia wiping out all community transmission of the virus several times even after re-introduction in the community.
The COVID-19 pandemic was confirmed to have reached South America on 26 February 2020 when Brazil confirmed a case in São Paulo. By 3 April, all countries and territories in South America had recorded at least one case.
The COVID-19 pandemic in Tuvalu is part of the ongoing worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The virus was confirmed to have reached Tuvalu on 20 May 2022. As of 31 August 2022, a total of 25,591 vaccine doses have been administered.
The COVID-19 pandemic was confirmed to have reached the Chilean island and special territory of Easter Island in March 2020.
The COVID-19 pandemic in American Samoa is part of the ongoing worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2. The COVID-19 pandemic was confirmed to have reached the unincorporated United States territory of American Samoa on 9 November 2020.
