China's Virologist Warns Against Another COVID Outbreak: ''Highly Likely''

China's famous virologist Shi Zhengli, also known as ‘Batwoman', has warned that another coronavirus outbreak is “highly likely” to take place in the future, South China Morning Post reported. The virologist in a recent research paper, titled 'Assessment and sero-diagnosis for coronaviruses with risk of human spillover' warned that the world must be prepared for another disease, just like COVID-19, because "if a coronavirus caused diseases to emerge before, there is a high chance it will cause future outbreaks."

In the study, Ms Zhengli and colleagues from the Wuhan Institute of Virology evaluated the human spillover risk of 40 coronavirus species. They found that half of these species are ''highly risky''. Of these, six are already known to have caused diseases that infected humans, while there is evidence that a further three caused disease or infected other animal species.

''It is almost certain that there will be future disease emergence and it is highly likely a [coronavirus] disease again,'' the study warned.

The study was based on an analysis of viral traits, including population, genetic diversity, host species, and any previous history of zoonosis, SCMP reported. Further, the study also identified hosts of the pathogen including natural hosts like bats and rodents, or possible intermediate hosts including camels, civets, pigs, or pangolins.  

However, other Chinese virologists dismissed the claims, while some others were reluctant to comment on Ms Zhengli's latest findings.

Meanwhile, another scientist from China's Centres for Disease Control and Prevention (CDC) told the publication on condition of anonymity that ''Chinese authorities are downplaying COVID-19, and some cities have stopped releasing infection data.''

The Wuhan Institute of Virology has been under increased scrutiny, with some US politicians promoting the theory that COVID-19 originated from an accidental leak from the lab. However, the head of US intelligence said there is no evidence for the claim, as per an AFP report. 

In May this year, World Health Organisation (WHO) chief also remarked that the world must get ready for the next pandemic, ''Disease X'', which might be "even deadlier" than Covid-19.  According to WHO website, the term "represents the knowledge that a serious international epidemic could be caused by a pathogen currently unknown to cause human disease".

It could be a new agent - a virus, a bacterium, or a fungus - without any known treatments. The WHO started using the term in 2018. A year later, COVID-19 began to spread across the world.

Sri Lanka Must Achieve Debt Restructuring By September: IMF

The International Monetary Fund on Tuesday reaffirmed that Sri Lanka must achieve its debt restructuring process by September, which is also the time for the global lender's formal review of the bailout facility it extended to the cash-strapped nation. On March 20, IMF extended a nearly $3 billion bailout facility to debt-ridden Sri Lanka that would help stabilise the country's economy after it was jolted by a devastating economic crisis last year. In a statement issued on Tuesday at the end of a nearly two weeks staff visit to Colombo to assess the progress made by Sri Lanka since the agreement was reached, the IMF said the two sides had discussed the developments on debt restructuring. "Sri Lanka must achieve debt restructuring by its first review due in September. We also discussed progress on debt restructuring, noting the ongoing discussions with both foreign and domestic creditors," the statement read. Sri Lanka is still struggling to normalise its crisis-hi...

Biden Warns "All Out War" Possible In Middle East

US President Joe Biden warned Wednesday of the possibility of an "all-out war" in the Middle East but said he was hopeful a settlement was still achievable for the conflict-torn region. Biden's comments as he appeared on ABC chat show "The View" came as Israel put troops on alert for possible entry into Lebanon and the war in Gaza grinds on. "An all-out war is possible," Biden said when asked about the situation. "What I think is, also, the opportunity is still in play to have a settlement that could fundamentally change the whole region." Biden appeared to raise the possibility of a ceasefire in Lebanon, where Israeli strikes targeting the Hezbollah militia have killed more than 600 people this week. "They have a possibility -- I don't want to exaggerate it -- there's a possibility if we can deal with a ceasefire in Lebanon that it can move into dealing with the West Bank as well," said Biden. Israel has been carrying ...

Amazon Rainforest Tribe's Secret To Healthy Life And Slow Ageing Revealed

Deep in the Amazon rainforest, a semi-nomadic indigenous community is thriving. This community defies conventional norms on ageing and health. The Tsimanes, consisting of 16,000 people, live a fully subsistence lifestyle, relying on hunting, foraging and farming to survive. Scientists have been studying this unique group for two decades, and have uncovered remarkable findings till now. Martina Canchi Nate, an 84-year-old Tsimanes woman, digs up yucca trees, cuts down plantain trees and carries heavy loads with ease, faster than her younger companions, as per a BBC report. This level of physical activity is not unusual among Tsimanes of her age. Researchers have discovered that this group has the healthiest arteries ever studied and brains that age more slowly than those in North America, Europe and elsewhere. The Tsimanes' secret lies in their active lifestyle, with an average of 16,000 to 17,000 steps per day. They spend less than 10 percent of daylight hours in sedentary activ...
