COVID-19 spreads even before people show symptoms, study says

Houston, Mar 15: Researchers, studying the novel coronavirus, have found that the time between cases in a chain of transmission is less than a week, and over 10 per cent of patients are infected by someone who has the virus, but does not show symptoms yet, a finding that may help public health officials contain the pandemic.

The study, published in the journal Emerging Infectious Diseases, estimated what's called the serial interval of the coronavirus by measuring the time it takes for symptoms to appear in two people with the virus -- the person who infects another, and the infected second person.

According to the researchers, including those from the University of Texas at Austin, the average serial interval for the novel coronavirus in China was approximately four days.

They said the speed of an epidemic depends on two things -- how many people each case infects, and how long it takes cases to spread.

The first quantity, the scientists said, is called the reproduction number, and the second is the serial interval.

Due to the short serial interval of the disease caused by the coronavirus -- COVID-19 -- they said, emerging outbreaks will grow quickly, and could be difficult to stop.

“Ebola, with a serial interval of several weeks, is much easier to contain than influenza, with a serial interval of only a few days,” said Lauren Ancel Meyers, study co-author from UT Austin.

Meyers explained that public health responders to Ebola outbreaks have much more time to identify and isolate cases before they infect others.

“The data suggest that this coronavirus may spread like the flu. That means we need to move quickly and aggressively to curb the emerging threat,” Meyers added.

In the study, the scientists examined more than 450 infection case reports from 93 cities in China, and found the strongest evidence yet that people without symptoms must be transmitting the virus -- known as pre-symptomatic transmission.

More than one in ten infections were from people who had the virus but did not yet feel sick, the scientists said.

While researchers across the globe had some uncertainty until now about asymptomatic transmission with the coronavirus, the new evidence could provide guidance to public health officials on how to contain the spread of the disease.

“This provides evidence that extensive control measures including isolation, quarantine, school closures, travel restrictions and cancellation of mass gatherings may be warranted,” Meyers said.

The researchers cautioned that asymptomatic transmission makes containment more difficult.

With hundreds of new cases emerging around the world every day, the scientists said, the data may offer a different picture over time.

They said infection case reports are based on people's memories of where they went and whom they had contact with, and if health officials move quickly to isolate patients, that may also skew the data.

“Our findings are corroborated by instances of silent transmission and rising case counts in hundreds of cities worldwide. This tells us that COVID-19 outbreaks can be elusive and require extreme measures,” Meyers said.

Washington, Jun 13: America's first-ever Hindu lawmaker Tulsi Gabbard has said that in this chaotic time, one can find certainty, strength, and peace in Bhagavad Gita.

In her message during a virtual commencement address, the 39-year-old Congresswoman from Hawaii said that it is a chaotic time and no one can say with certainty what tomorrow looks like.

"... but we find certainty, strength, and peace in the practice of Bhakti Yoga and Karma Yoga taught to us by Krishna in the Bhagavad Gita," Tulsi Gabbard told the 'Class of 2020 for Hindu students''.

Her address came amidst protests in the US against the killing of African-American George Floyd by a white police officer in Minneapolis.

The country has been swept by protests since George Floyd's custodial death on May 25 with thousands of people mounting pressure for changes to the law enforcement practices.

The first-ever virtual Hindu commencement was organised by the Hindu Students Council on June 7, which drew thousands of viewers on Facebook and YouTube Live, all coming together in solidarity during the ongoing COVID-19 crisis.

According to Johns Hopkins Coronavirus Resource Center, the contagion has infected over 76,00,000 people and killed more than 4,25,000 across the world. The US is the worst affected country with over 2.04 million cases and more than 1,14,000 deaths.

The COVID-19, which originated in China''s Wuhan city in December last year, has also battered the world economy with the International Monetary Fund saying that the global economy is bound to suffer a "severe recession".

Scientists are racing against time to find a vaccine or medicine for its treatment.

Hundreds of graduates from the US, Canada, the UK, India and Australia attended to commemorate their graduation in a unique way - by celebrating their shared Hindu values.

Professor Subhash Kak served as the ceremony's Grand Marshall.

"As you think about this new chapter in your lives, ask yourself what is my purpose in life? It is a deep question that if you can recognise now that your purpose is to serve God and God''s children, practicing Karma Yoga, then you can lead a truly successful life," Tulsi Gabbard said.

"Success is not defined by temporary material things, trinkets, glittery objects or accomplishments - but a deeply successful and happy life centered around service," she added.

The Iraq war veteran ended her presidential campaign in March and offered her full support to former vice president Joe Biden, 77, who is all set to challenge Republican incumbent Donald Trump, 73, in November elections.

The commencement address focused heavily on themes from the Bhagavad Gita, a timeless historical text that many Hindus consider their moral framework.

Professor Kak, Regent Professor at Oklahoma State University and 2019 Padma Shri recipient, read out the names of the graduating students.

"I exhort you - the graduating students - to be the leaders of the new world where education is less of the mind of a vessel to be filled with information (usually forgotten after the semester is over), and more of a flame that is lit as envisioned by our Vedic sages," he said.

The student speakers were from many university campuses, including the Massachusetts Institute of Technology, Princeton, and Stanford.

The programme included offerings of Hindu prayers, recitation of a traditional graduation message from the Upanishads, and a symbolic conferral of degrees to high school and college graduate.

Founded in 1990, Hindu Students Council is North America''s largest pan-Hindu youth organisation.

For the first time in the 15 years of the Global Risks Report, the climate change and environment risk has occupied all the top five slots.

According to the 15th edition of the World Economic Forum's (WEF) Global Risks Report, the top five risks in terms of likelihood are extreme weather, climate action failure, natural disasters, biodiversity loss and human-made environmental disasters. They all fall in the one category of climate change and related environmental disasters.

WEF President Borge Brende said the world was feeling long-mounting and interconnected risks.

The report also points to how citizens are protesting across the world as discontent rises with failed systems that are creating inequality. The citizens' discontent had hardened with systems that had failed to promote advancement, it said.

"Disapproval of how governments are addressing profound economic and social issues has sparked protests throughout the world, potentially weakening the ability of governments to take decisive action should a downturn occur. Without economic and social stability, countries could lack the financial resources, fiscal margin, political capital or social support needed to confront key global risks," it said.

Listing the grim scenario, Borge said the global economy was faced with "synchronised slowdown", the past five years had been the warmest on record and cyber attacks were expected to increase this year.

The report warns that while the myriad risks were rising, time was running out on how to prevent them.

Borge said the growing palpability of shared economic, environmental and societal risks indicated that the horizon had shortened for preventing "or even mitigating" some of the direst consequences of global risks.

"It's sobering that in the face of this development, when the challenges before us demand immediate collective action, fractures within the global community appear to only be widening," he said.

The report points to grave concern about the consequences of continued environmental degradation, including the record pace of species decline.

Pointing to an unsettled geopolitical environment, the report said today's risk landscape was one in which new centres of power and influence were forming and old alliance structures and global institutions were being tested.

"While these changes can create openings for new partnership structures in the immediate term, they are putting stress on systems of coordination and challenging norms around shared responsibility. Unless stakeholders adapt multilateral mechanisms for this turbulent period, the risks that were once on the horizon will continue to arrive," it said.

Calling it a "an unsettled world", the WEF report notes that powerful economic, demographic and technological forces were shaping a new balance of power. "The result is an unsettled geopolitical landscape in which states are increasingly viewing opportunities and challenges through unilateral lenses," it said.

"What were once givens regarding alliance structures and multilateral systems no longer hold as states question the value of long-standing frameworks, adopt more nationalist postures in pursuit of individual agendas and weigh the potential geopolitical consequences of economic decoupling. Beyond the risk of conflict, if stakeholders concentrate on immediate geo-strategic advantage and fail to re-imagine or adapt mechanisms for coordination during this unsettled period, opportunities for action on key priorities may slip away," the WEF said.

In a chapter on risks to economic stability and social cohesion, it said a challenging economic climate might persist this year and members of the multi-stakeholder community saw "economic confrontations" and "domestic political polarisation" as the top risks in 2020.

The report also warned of downward pressure on the global economy from macroeconomic fragilities and financial inequality. These pressures continued to intensify in 2019, increasing the risk of economic stagnation.

Low trade barriers, fiscal prudence and strong global investment, once seen as fundamentals for economic growth, are fraying as leaders advance nationalist policies. The margins for monetary and fiscal stimuli are also narrower than before the 2008-2009 financial crisis, creating uncertainty about how well countercyclical policies will work.

The strategic partners for the WEF report included Marsh & McLennan and Zurich Insurance Group. The academic advisers were National University of Singapore, Oxford Martin School, University of Oxford and Wharton Risk Management and Decision Processes Center, University of Pennsylvania.
