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 contained 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 the station 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 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.
Southernmost settlements are cities, towns, weather stations or permanent military bases which are farther south than latitude 45°S. They are closely related to the Southern Ocean or either the Roaring Forties or Furious Fifties. Antarctic bases are excluded due to not having a permanent population.
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 on 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 with British and Chilean claims in Antarctica. None of these claims have widespread international recognition.
Colonization of Antarctica is the establishing and maintaining of control over Antarctic land for exploitation and possibly settlement.
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 current research stations of the Antarctic are constructed either on rocks or on ice that are fixed in place.
Villa Las Estrellas is a permanently inhabited outpost on King George Island within the Chilean Antarctic claim, the Chilean Antarctic Territory, and also within the Argentine and British Antarctic claims.
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, at the west end of King George Island, South Shetland Islands. Situated alongside the Escudero Station in Villa Las Estrellas 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 a part of West Antarctica and nearby islands claimed by Chile. It comprises the region south of 60°S latitude and between longitudes 53°W and 90°W, partially overlapping the Antarctic claims of Argentina and the United Kingdom. It constitutes the Antártica commune of Chile.
Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as China, India, Italy, Japan, Pakistan, Russia, South Africa (SANAE), Poland, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom.
Telecommunications in Antarctica is provided by the organizations that have established research stations on the continent. Antarctica is not formally designated by the International Telecommunication Union (ITU) in any of the world zones.
Antarctica contains research stations and field camps that are staffed seasonally or year-round, and former whaling settlements. Approximately 12 nations, all signatory to the Antarctic Treaty, send personnel to perform seasonal (summer) or year-round research on the continent and in its surrounding oceans. There are also two official civilian settlements: Villa Las Estrellas in Base Presidente Eduardo Frei Montalva operated by Chile, and Fortín Sargento Cabral in Esperanza Base operated by Argentina.
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).
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. It spread to other areas of Asia, and then worldwide in early 2020.
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 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 following events occurred in Antarctica in 2020.
