Hijab-wearing White House staffer quits Trump administration in 8 days

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.

The Hague, Jun 22: Finding inner peace is crucial for the armed forces and yoga is a beautiful way to find the balance, Dutch Defence Minister Ank Bijleveld has said, thanking India for the "wonderful gift" to the world.

Yoga has been gaining global popularity in recent years for the many benefits it has on one's physiology, psychology and spirituality.

Bijleveld participated in the online International Yoga Day celebrations organised by the Indian Embassy here on Sunday.

"The minister thanked India for the wonderful gift of yoga to the world," a statement issued by the embassy said on Monday.

She said finding inner peace is crucial for a man and woman in uniform and yoga is a beautiful way to find the balance, it noted.

Bijleveld said yoga has formed a part of the training for the Dutch armed forces for the last 15 years and there are 130 yoga instructors.

The representatives of the Dutch Army joined by the Dutch Police personnel demonstrated their yoga skills as part of the online celebrations, the statement said.

The sixth International Yoga Day celebrations was streamed to 145,000 followers of the embassy's Facebook, Twitter, Instagram and YouTube channels as well as on its website. It was also streamed on the website of the non-profit foundation Stichting International Yoga Day.

Ambassador of India to The Netherlands Venu Rajamony inaugurated the celebrations. This was followed by Prime Minister Narendra Modi's video message and 3D animated videos of yoga with him.

The event was participated by a host of prominent Dutch and Indian personalities, including Ambassadors of various countries based in The Hague.

Dutch actress Afke Reijenga, extreme sportsman Wim Hof -- popularly known as 'The Iceman' and singers Charlie Dee and Anouk Maas were amongst the Dutch celebrities who participated in the event, the statement said.

Messages and artistic contributions by spiritual leader Sri Sri Ravi Shankar, internationally acclaimed flautist Pandit Hariprasad Chaurasia, violin maestro L Subramaniam, playback singers Kavita Krishnamurthy and Vijay Prakash, chess grandmaster Viswanathan Anand and film stars Raadhika, Sarathkumar and Bhumika Chawla featured in the programme.

UN, May 26: Countries could see a "second peak" of coronavirus cases during the first wave of the pandemic if lockdown restrictions were lifted too soon, the World Health Organization (WHO) has warned.

Mike Ryan, the WHO's head of emergencies, told a briefing on Monday that the world was "right in the middle of the first wave", the BBC reported.

He said because the disease was "still on the way up", countries need to be aware that "the disease can jump up at any time".

"We cannot make assumptions that just because the disease is on the way down now that it's going to keep going down," Ryan said.

There would be a number of months to prepare for a second peak, he added.

The stark warning comes as countries around the world start to gradually ease lockdown restrictions, allowing shops to reopen and larger groups of people to gather.

Experts have said that without a vaccine to give people immunity, infections could increase again when social-distancing measures are relaxed.

Ryan said countries where cases are declining should be using this time to develop effective trace-and-test regimes to "ensure that we continue on a downwards trajectory and we don't have an immediate second peak".

Also on Monday, Tedros Adhanom Ghebreyesus, WHO Director-General, said that a clinical trial of hydroxychloroquine (HCQ) on COVID-19 patients has come to "a temporary pause", while the safety data of the the anti-malaria drug was being reviewed.

According to the WHO chief, The Lancet medical journal on May 22 had published an observational study on HCQ and chloroquine and its effects on COVID-19 patients that have been hospitalized, reports Xinhua news agency.

The authors of the study reported that among patients receiving the drug, when used alone or with a macrolide, they estimated a higher mortality rate.

"The Executive Group of the Solidarity Trial, representing 10 of the participating countries, met on Saturday (May 23) and has agreed to review a comprehensive analysis and critical appraisal of all evidence available globally," Tedros said in a virtual press conference.

The developments come as the total number of global COVID-19 cases has increased to 5,508,904, with 346,508 deaths, according to the Johns Hopkins University.
