President Trump vows to immediately deport up to 3 million immigrants

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.

Moscow, Jul 2: Russian voters approved changes to the constitution that will allow President Vladimir Putin to hold power until 2036, but the weeklong plebiscite that concluded Wednesday was tarnished by widespread reports of pressure on voters and other irregularities.

With most of the nation's polls closed and 20% of precincts counted, 72% voted for the constitutional amendments, according to election officials.

For the first time in Russia, polls were kept open for a week to bolster turnout without increasing crowds casting ballots amid the coronavirus pandemic a provision that Kremlin critics denounced as an extra tool to manipulate the outcome.

A massive propaganda campaign and the opposition's failure to mount a coordinated challenge helped Putin get the result he wanted, but the plebiscite could end up eroding his position because of the unconventional methods used to boost participation and the dubious legal basis for the balloting.

By the time polls closed in Moscow and most other parts of Western Russia, the overall turnout was at 65%, according to election officials. In some regions, almost 90% of eligible voters cast ballots.

On Russia's easternmost Chukchi Peninsula, nine hours ahead of Moscow, officials quickly announced full preliminary results showing 80% of voters supported the amendments, and in other parts of the Far East, they said over 70% of voters backed the changes.

Kremlin critics and independent election observers questioned the turnout figures.

We look at neighboring regions, and anomalies are obvious there are regions where the turnout is artificially (boosted), there are regions where it is more or less real, Grigory Melkonyants, co-chair of the independent election monitoring group Golos, told The Associated Press.

Putin voted at a Moscow polling station, dutifully showing his passport to the election worker. His face was uncovered, unlike most of the other voters who were offered free masks at the entrance.

The vote completes a convoluted saga that began in January, when Putin first proposed the constitutional changes.

He offered to broaden the powers of parliament and redistribute authority among the branches of government, stoking speculation he might seek to become parliamentary speaker or chairman of the State Council when his presidential term ends in 2024.

His intentions became clear only hours before a vote in parliament, when legislator Valentina Tereshkova, a Soviet-era cosmonaut who was the first woman in space in 1963, proposed letting him run two more times.

The amendments, which also emphasize the primacy of Russian law over international norms, outlaw same-sex marriages and mention a belief in God as a core value, were quickly passed by the Kremlin-controlled legislature.

Putin, who has been in power for more than two decades longer than any other Kremlin leader since Soviet dictator Josef Stalin said he would decide later whether to run again in 2024.

He argued that resetting the term count was necessary to keep his lieutenants focused on their work instead of darting their eyes in search for possible successors.

Analyst Gleb Pavlovsky, a former Kremlin political consultant, said Putin's push to hold the vote despite the fact that Russia has thousands of new coronavirus infections each day reflected his potential vulnerabilities.

Putin lacks confidence in his inner circle and he's worried about the future, Pavlovsky said.

He wants an irrefutable proof of public support.

Even though the parliament's approval was enough to make it law, the 67-year-old Russian president put his constitutional plan to voters to showcase his broad support and add a democratic veneer to the changes.

But then the coronavirus pandemic engulfed Russia, forcing him to postpone the April 22 plebiscite.

The delay made Putin's campaign blitz lose momentum and left his constitutional reform plan hanging as the damage from the virus mounted and public discontent grew.

Plummeting incomes and rising unemployment during the outbreak have dented his approval ratings, which sank to 59%, the lowest level since he came to power, according to the Levada Center, Russia's top independent pollster.

Moscow-based political analyst Ekaterina Schulmann said the Kremlin had faced a difficult dilemma: Holding the vote sooner would have brought accusations of jeopardizing public health for political ends, while delaying it raised the risks of defeat.

Holding it in the autumn would have been too risky, she said.

In Moscow, several activists briefly lay on Red Square, forming the number 2036 with their bodies in protest before police stopped them.

Some others in Moscow and St. Petersburg staged one-person pickets and police didn't intervene.

Several hundred opposition supporters rallied in central Moscow to protest the changes, defying a ban on public gatherings imposed for the coronavirus outbreak. Police didn't intervene and even handed masks to the participants.

Authorities mounted a sweeping effort to persuade teachers, doctors, workers at public sector enterprises and others who are paid by the state to cast ballots. Reports surfaced from across the vast country of managers coercing people to vote.

The Kremlin has used other tactics to boost turnout and support for the amendments.

Wuhan, Jan 31: The World Health Organization declared a global emergency over the new coronavirus, as China reported Friday the death toll had climbed to 213 with nearly 10,000 infections.

The UN health agency based in Geneva had initially downplayed the threat posed by the disease, but revised its risk assessment after crisis talks.

suspended or reduced service to China include British Airways, German flag carrier Lufthansa, American Airlines, KLM and United.

Chinese efforts to halt the virus have included the suspension of classes nationwide and an extension of the Lunar New Year holiday.

All football matches across the country also will be postponed, the Chinese Football Association said on Thursday, including games in the top-tier Chinese Super League.

World stock markets tumbled again Thursday on fears that trouble in the "world's factory" would upset global supply chains and dent profits.

Toyota, IKEA, Starbucks, Tesla, McDonald's and tech giant Foxconn were among the corporate giants temporarily freezing production or closing large numbers of outlets in China.

Volkswagen announced Thursday its China joint-venture plants would not start production again before February 9.

US Federal Reserve Chairman Jerome Powell said the coronavirus posed a fresh risk to the world economy.

Throughout China, signs of paranoia multiplied, with residents of some Beijing residential compounds erecting makeshift barriers to their premises.

In one of many similar photos posted online, a man wearing a surgical mask and brandishing a traditional martial arts weapon squatted on a barricade outside a Chinese village, near a sign saying: "Outsiders forbidden from entering".

The crisis has caused food prices to spike, and the central government on Thursday blamed this partly on overzealous preventive measures, issuing a directive banning any roadblocks or other hindrances to food shipments.
