Ten members of India's dwindling Great Andamanese tribe have tested positive for coronavirus, officials said Thursday, fuelling concerns about the safety of the group and other indigenous people in the remote archipelago.
Six of the 10 have recovered and are in home quarantine, officials told AFP, while the rest are undergoing treatment at a local hospital.
Just over 50 Great Andamanese people survive today and live on the tiny Strait Island where the Indian government looks after their food and shelter.
The Andaman and Nicobar Islands, a chain in the Indian Ocean with a population of some 400,000, has reported 2,268 coronavirus cases so far with 37 deaths.
Indian authorities sent a team of health officials to Strait Island on Sunday after six members of the tribe tested positive in the archipelago's capital Port Blair recently.
Some of the tribe's members travel to Port Blair where they have government jobs.
"The team tested 37 samples and four members of the Great Andamanese tribe were found to be positive. They are admitted in hospital," Avijit Ray, a senior health officer in charge of disease management in the Andamans, told AFP.
Sanjiv Mittal, a senior government officer for tribal welfare, told AFP authorities were doing their best to keep all the members safe and healthy.
- Extremely vulnerable -
Anthropologists and activists for isolated tribal communities say more than 5,000 Great Andamanese lived in the islands when British settlers arrived in the 19th century.
However, hundreds were killed in conflicts as they defended their territories from British invasion, and thousands more were wiped out in epidemics of measles, influenza and syphilis, according to Survival International.
In recent days, concerns have grown for the safety of the Great Andamanese and other tribes, including the remote Jarawa and the Sentinelese people.
Poachers continue to invade their territory despite strict government restrictions.
Last week, eight fishermen were arrested for illegally entering the Jarawa's territory, local media reported.
In 2018, a 26-year-old American missionary seeking to convert the nomadic hunter-gatherer tribe was killed after he secretly visited the North Sentinel island.
His body was never retrieved.
Outsiders are banned from visiting the island, to protect the Sentinelese way of life and avoid exposing them to infectious diseases.
As one of the most isolated tribes in the world, the Sentinelese are extremely vulnerable to diseases from outsiders, especially during a global pandemic such as the coronavirus, experts say.
"The Andaman authorities must act urgently to prevent the virus reaching more Great Andamanese and to prevent infection in the other tribes," said Sophie Grig, a senior researcher with Survival.
"The waters around North Sentinel must be properly policed and no outsiders should enter the territories of any of the Andaman tribes without their consent."
She added: "We've certainly seen in the US, in Brazil, in Peru, indigenous communities (being) disproportionately hit. In Brazil where there are more than a hundred uncontacted tribes still living, (the) fear of the disease is getting into those communities."
The virus has already hit tribes in Brazil and Peru hard, including some of the isolated Amazon tribes.
According to the Brazilian Indigenous Peoples' Association, 26,000 indigenous people have been infected and 690 have died during the country's pandemic.
India is the third worst-hit country in the world behind the US and Brazil, with more than three million coronavirus cases.
There, some 60,000 people have died from the infection so far.
