'US is leader of world terrorism': Iran President Hassan Rouhani

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.

Islamabad, Feb 29: A coalition comprising digital media giants Facebook, Google and Twitter (among others) have spoken out against the new regulations approved by the Pakistani government for social media, threatening to suspend services in the country if the rules were not revised, it was reported.

In a letter to Prime Minster Imran Khan earlier this month, the Asia Internet Coalition (AIC) called on his government to revise the new sets of rules and regulations for social media, The News International reported on Friday.

"The rules as currently written would make it extremely difficult for AIC Members to make their services available to Pakistani users and businesses," reads the letter, referring to the Citizens Protection Rules (Against Online Harm).

The new set of regulations makes it compulsory for social media companies to open offices in Islamabad, build data servers to store information and take down content upon identification by authorities.

Failure to comply with the authorities in Pakistan will result in heavy fines and possible termination of services.

It said that the regulations were causing "international companies to re-evaluate their view of the regulatory environment in Pakistan, and their willingness to operate in the country".

Referring to the rules as "vague and arbitrary in nature", the AIC said that it was forcing them to go against established norms of user privacy and freedom of expression.

"We are not against regulation of social media, and we acknowledge that Pakistan already has an extensive legislative framework governing online content. However, these Rules fail to address crucial issues such as internationally recognized rights to individual expression and privacy," The News International quoted the letter as saying.

According to the law, authorities will be able to take action against Pakistanis found guilty of targeting state institutions at home and abroad on social media.

The law will also help the law enforcement authorities obtain access to data of accounts found involved in suspicious activities.

It would be the said authority's prerogative to identify objectionable content to the social media platforms to be taken down.

In case of failure to comply within 15 days, it would have the power to suspend their services or impose a fine worth up to 500 million Pakistani rupees ($3 million).

San Francisco, Mar 14: Microsoft on friday announced that co-founder Bill Gates has left its board of directors to devote more time to philanthropy.

The 64-year-old stopped being involved in day-to-day operations at the firm more than a decade ago, turning his attention to the foundation he launched with his wife, Melinda.

Gates served as chairman of Microsoft's board of directors until early in 2014 and has now stepped away entirely, according to the Redmond-based technology giant.

“It's been a tremendous honor and privilege to have worked with and learned from Bill over the years,” Microsoft chief executive and company veteran Satya Nadella said in a release.

Nadella said Microsoft would continue to benefit from Gates' “technical passion and advice” in his continuing role as a technical advisor.
“I am grateful for Bill's friendship and look forward to continuing to work alongside him,” he added.

Gates left his CEO position in 2000, handing the company reins to Steve Ballmer to devote more time to his charitable foundation.

He gave up the role of chairman at the same time Nadella became Microsoft's third CEO in 2014.

Regularly listed among the world's richest people, William H. Gates was a geeky-looking young man when he and Paul Allen co-founded Microsoft in 1975.

Gates went on to turn his attention from software to fighting disease and other humanitarian challenges with his wife, under the auspices of the Bill and Melinda Gates Foundation.
