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.

Beijing, June 30: China said on Tuesday it was concerned about India’s decision to ban Chinese mobile apps such as Bytedance’s TikTok and Tencent’s WeChat and was making checks to verify the situation.

Chinese foreign ministry spokesman Zhao Lijian told reporters during a daily briefing that (the Prime Minister Narendra Modi-led government of) India has a responsibility to uphold the rights of Chinese businesses.

India on Monday banned 59, mostly Chinese, mobile apps in its strongest move yet targeting China in the online space since a border crisis erupted between the two countries this month.

The apps are “prejudicial to the sovereignty and integrity of India, the defence of India, the security of state and public order", the ministry of information technology said in a statement, which came two weeks after 20 Indian Army personnel were killed in a violent clash on the India-China border in Ladakh.

The companies have been invited to offer clarifications before a government panel, which will decide whether the ban can be removed or will stay.

The move also came ahead of military and diplomatic talks between India and China scheduled this week.

Oakland, Jun 2: Facebook employees are using Twitter to register their frustration over CEO Mark Zuckerberg's decision to leave up posts by President Donald Trump that suggested protesters in Minneapolis could be shot.

While Twitter demoted and placed a warning on a tweet about the protests that read, in part, that “when the looting starts the shooting starts,” Facebook has let it stand, with Zuckerberg laying out his reasoning in a Facebook post Friday.

“I know many people are upset that we've left the President's posts up, but our position is that we should enable as much expression as possible unless it will cause imminent risk of specific harms or dangers spelled out in clear policies,” Zuckerberg wrote.

Trump's comment evoked the civil-rights era by borrowing a phrase used in 1967 by Miami's police chief to warn of an aggressive police response to unrest in black neighborhoods.

On Monday, Facebook employees staged a virtual “walkout” to protest the company's decision not to touch the Trump posts according to a report in the New York Times, which cited anonymous senior employees at Facebook.

The Times report says “dozens” of Facebook workers “took the day off by logging into Facebook's systems and requesting time off to support protesters across the country." “I work at Facebook and I am not proud of how we're showing up.

The majority of coworkers I've spoken to feel the same way. We are making our voice heard,” tweeted Jason Toff, a director of product management at Facebook who's been at the company for a year.

Toff, who has a verified Twitter account, had 131,400 “likes” and thousands of retweets of his comment. He did not immediately respond to a message seeking comment on Monday.

“I don't know what to do, but I know doing nothing is not acceptable. I'm a FB employee that completely disagrees with Mark's decision to do nothing about Trump's recent posts, which clearly incite violence. I'm not alone inside of FB.

There isn't a neutral position on racism,” tweeted another employee, design manager Jason Stirman.

Stirman did not immediately respond to a request for comment on Monday. Sara Zhang, a product designer at the company, tweeted that Facebook's “decision to not act on posts that incite violence ignores other options to keep our community safe.

The policy pigeon holes us into addressing harmful user-facing content in two ways: keep content up or take it down.” “I believe that this is a self-imposed constraint and implore leadership to revisit the solution,” she continued. Zhang declined to comment to The Associated Press.

Representatives for Facebook did not immediately respond to messages for comment.

Twitter has historically taken stronger stances than its larger rival, including a complete ban on political advertisements that the company announced last November.

That's partly because Facebook, a much larger company with a broader audience,targeted by regulators over its size and power, has more to lose. And partly because the companies' CEOs don't always see eye to eye on their role in society.

Over the weekend, Twitter changed the background and logo if its main Twitter account to black from its usual blue in support of the Black Lives Matter protesters and added a #blacklivesmatter hashtag. Facebook did the same with its own logo on its site, though without the hashtag.
