“Zombie viruses” as old as 48,500 years could make a comeback as the Arctic permafrost melts due to climate change, scientists have said.
Researcher Jean-Michel Claverie and his team have managed to revive the frozen virus and other strains, including a 27,000 year-old sample taken from the stomach of a woolly mammoth.
It is wrong to suggest that “zombie viruses are not a public health threat”, the Emeritus professor of medicine and genomics at the Aix-Marseille University School of Medicine in Mareille wrote in a report released last month.
Climate change is causing the temperature to warm twice as fast in the Arctic, the report said.
“One of the most visible consequences is the global thawing of permafrost at increasing depths. This rapid permafrost thaw causes mobilisation of ancient organic matter previously preserved for millennia in permafrost deep layers.”
Kimberley Miner, climate scientist at the Nasa Jet Propulsion Laboratory at the California Institute of Technology in Pasadena, told CNN that it is important to keep the permafrost from thawing, despite the low risks of these viruses being unleashed.
“There’s a lot going on with the permafrost that is of concern, and (it) really shows why it’s super important that we keep as much of the permafrost frozen as possible,” she said.
Permafrost, which makes up 25 per cent of the Northern Hemisphere, is cold and devoid of oxygen. Being underground means light cannot penetrate it and it houses antibiotic-resistant microorganisms.
Mr Claverie's report also says that an anthrax epidemic that has been killing reindeers “has been linked to the deeper thawing of the permafrost active layer at the soil surface during exceptionally hot summers”.
He warned that unlike with bacteria, there isn't a “broad-spectrum” solution to viruses.

What is Diwali?
The Hindu festival is at once a celebration of the autumn harvest and the triumph of good over evil, as outlined in the Ramayana.
According to the Sanskrit epic, penned by the sage Valmiki, Diwali marks the time that the exiled king Rama – a mortal with superhuman powers – returned home to the city of Ayodhya with his wife Sita and brother Lakshman, after vanquishing the 10-headed demon Ravana and conquering his kingdom of Lanka. The people of Ayodhya are believed to have lit thousands of earthen lamps to illuminate the city and to guide the royal family home.
In its current iteration, Diwali is celebrated with a puja to welcome the goodness of prosperity Lakshmi (an incarnation of Sita) into the home, which is decorated with diyas (oil lamps) or fairy lights and rangoli designs with coloured powder. Fireworks light up the sky in some parts of the word, and sweetmeats are made (or bought) by most households. It is customary to get new clothes stitched, and visit friends and family to exchange gifts and greetings.

Salah in numbers
€39 million: Liverpool agreed a fee, including add-ons, in the region of €39m (nearly Dh176m) to sign Salah from Roma last year. The exchange rate at the time meant that cost the Reds £34.3m - a bargain given his performances since.
13: The 25-year-old player was not a complete stranger to the Premier League when he arrived at Liverpool this summer. However, during his previous stint at Chelsea, he made just 13 Premier League appearances, seven of which were off the bench, and scored only twice.
57: It was in the 57th minute of his Liverpool bow when Salah opened his account for the Reds in the 3-3 draw with Watford back in August. The Egyptian prodded the ball over the line from close range after latching onto Roberto Firmino's attempted lob.
7: Salah's best scoring streak of the season occurred between an FA Cup tie against West Brom on January 27 and a Premier League win over Newcastle on March 3. He scored for seven games running in all competitions and struck twice against Tottenham.
3: This season Salah became the first player in Premier League history to win the player of the month award three times during a term. He was voted as the division's best player in November, February and March.
40: Salah joined Roger Hunt and Ian Rush as the only players in Liverpool's history to have scored 40 times in a single season when he headed home against Bournemouth at Anfield earlier this month.
30: The goal against Bournemouth ensured the Egyptian achieved another milestone in becoming the first African player to score 30 times across one Premier League campaign.
8: As well as his fine form in England, Salah has also scored eight times in the tournament phase of this season's Champions League. Only Real Madrid's Cristiano Ronaldo, with 15 to his credit, has found the net more often in the group stages and knockout rounds of Europe's premier club competition.
