Ensure polls not influenced, work closely with EC: Parl panel to Twitter

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.

Twitter has hinted that it is planning a paid subscription platform that can be reused by other teams in the future.

The news that the micro-blogging platform is building a subscription platform with a team codenamed "Gryphon" resulted in Twitter stock rising over 8% on Wednesday.

Twitter revealed its plan via a job listing that seeks a full-stack senior software engineer in New York to join "Gryphon".

Interestingly, Twitter "edited" the job listing once the news broke, removing the part about "Gryphon" and any mention of their internal team or their subscription feature. The listing said the company is looking for an Android engineer to "work on a bevy of backend engineering teams to build components that allow for experimentation to deliver the best experience possible to all of our users".

Later, Twitter users noticed that the company restored the earlier job listing that mentioned the upcoming subscription platform and "Gryphon".

A spokesperson for Twitter told CNN on Wednesday that it's only a job posting, not a product announcement.

This is not the first time Twitter has thought of a paid product. 

In 2017, it sent out a survey to users and a preview of what a premium offering of its TweetDeck app might look like, including breaking news alerts and more analytics, according to The Verge.

"We're conducting this survey to assess the interest in a new, more enhanced version of Tweetdeck. We regularly conduct user research to gather feedback about people's Twitter experience and to better inform our product investment decisions, and we're exploring several ways to make TweetDeck even more valuable for professionals," a Twitter spokesperson had said at that time.

Dubai, Mar 23: The United Arab Emirates announced on Monday it will temporarily suspend all passenger and transit flights amid the novel coronavirus outbreak.

The Emirati authorities "have decided to suspend all inbound and outbound passenger flights and the transit of airline passengers in the UAE for two weeks as part of the precautionary measures taken to curb the spread of the COVID-19", reported the official state news agency, WAM.

It said the decision -- which is subject to review in two weeks -- will take effect in 48 hours, adding: "Cargo and emergency evacuation flights would be exempt."

The UAE, whose international airports in Abu Dhabi and Dubai are major hubs, announced on Friday its first two deaths from the COVID-19 disease, having reported more than 150 cases so far.

Monday's announcement came hours after Dubai carrier Emirates announced it would suspend all passenger flights by March 25.

But the aviation giant then reversed its decision, saying it "received requests from governments and customers to support the repatriation of travellers" and will continue to operate passenger flights to 13 destinations.

Emirates had said it will continue to fly to the United Kingdom, Switzerland, Hong Kong, Thailand, Malaysia, the Philippines, Japan, Singapore, South Korea, Australia, South Africa, the United States and Canada.

"We continue to watch the situation closely, and as soon as things allow, we will reinstate our services," said the airline's chairman and CEO, Sheikh Ahmed bin Saeed Al-Maktoum.

Gulf countries have imposed various restrictions to combat the spread of the novel coronavirus pandemic, particularly in the air transport sector.

The UAE has stopped granting visas on arrival and forbidden foreigners who are legal residents but are outside the country from returning.
