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.
