Donald Trump lifts Turkey sanctions, quits ‘blood-stained’ Syria

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.

Mar 6: UK stocks fell again on Friday as growing economic risks from the coronavirus outbreak shattered investor confidence, with Britain recording its first death from the pathogen.

A 1.5% fall for the FTSE 100 erased the blue-chip index's gains from earlier this week. Export-heavy companies have now lost over $230 billion in value since the epidemic sparked a worldwide rout last week.

The domestically focussed mid-cap index was down 1.9%.

Cruise operator Carnival dropped 4.2% to its lowest level since 2012, a day after its Grand Princess ocean liner was barred from returning to its home port of San Francisco on virus fears.

Britain said an older person with underlying health problems had succumbed to the flu-like virus on Thursday, while the number of infections jumped to 115.

In company news, drug maker AstraZeneca fell 1% after it said its treatment for a form of bladder cancer failed to meet the main goal of improving overall survival in patients in a late-stage study.

United Nations, Apr 28: UN chief Antonio Guterres has warned that extremist groups are taking advantage of the COVID-19 lockdowns and intensifying efforts on social media to recruit youths online by exploiting their anger and despair, asserting that the world cannot afford a lost generation due to the unprecedented global health crisis.

The UN Secretary-General made the remarks on Monday during a video conference to review the five years since its adoption of a landmark resolution on youth, peace and security.

We can already see such groups taking advantage of the COVID-19 lockdowns, intensifying their efforts on social media to spread hatred and to recruit young people who may be spending more time at home and online, he said.

Guterres told the Security Council that even before the current crisis, young people were facing enormous challenges.

Listing startling numbers, he said one of every five young people was already not in education, training or employment and one of every four is affected by violence or conflict. Every year, 12 million girls become mothers while they themselves are still children.

These frustrations and, frankly, failures to address them by those in power today, fuel declining confidence in political establishments and institutions. And when such a cycle takes hold, it is all too easy for extremist groups to exploit the anger and despair, and the risk of radicalisation climbs, he said.

Issuing a call to action on youth, peace and security, Guterres said the world cannot afford a lost generation of youth, their lives set back by COVID-19 and their voices stifled by a lack of participation. Let us do far more to tap their talents as we tackle the pandemic and chart a recovery that leads to a more peaceful, sustainable and equitable future for all.

With over 1.54 billion children and youth out-of-school and young people acutely feeling the impact of the COVID-19 crisis, Guterres said countries must do more to harness the talents of young people to address the crisis and its aftermath.

In presenting his first report on the Security Council resolution, the UN chief said youth were already confronting numerous challenges even before the pandemic, including in accessing education, or through being affected by violence and conflict. Those pressing for peace or upholding human rights have been threatened.

Despite these obstacles, young people across the world have joined the common fight against the coronavirus disease, supporting both frontline workers and people in need. And they continue to push for change.

UN Youth Envoy Jayathma Wickramanayake spoke of the need for more meaningful partnerships between young people and the civil society organisations and government institutions that work on the youth, peace and security (YPS) agenda.

To date, there are no national action plans on YPS but I'm pleased to note that in some countries, these are in the process of development, she said.

For a national roadmap to be successful, a participatory, transparent and youth-led process with adequate resources are needed, she said.

Issuing his four-point call to action for the Council, Guterres urged members to do more to address the various challenges facing young people.

He also called for investment in youth participation, but also in their organisations and initiatives.

We must strengthen human rights protections and protect the civic space on which youth participation depends, he said. And fourth, we must emerge from the COVID-19 crisis with a determination to recover better - massively increasing our investment in young people's capacities as we deliver the Sustainable Development Goals.
