Indian-American teen wins top science award worth USD 250,000

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.

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.

Washington, Jun 26: The US is reviewing its global deployment of forces to ensure it is postured appropriately to counter the People's Liberation Army, given the increasing threat posed by China to Asian countries like India, Malaysia, Indonesia, and the Philippines, Secretary of State Mike Pompeo said on Thursday.

Mr Pompeo made those remarks in response to a question during the virtual Brussels Forum 2020 of the German Marshall Fund.

"We're going to make sure we're postured appropriately to counter the PLA. We think that the challenge of our times, and we're going to make sure we have resources in place to do that," Mr Pompeo said.
 
The force posture review is being done at the direction of President Donald Trump, as part of which the US is reducing the number of its troops in Germany from about 52,000 to 25,000, he said.

Mike Pompeo said that the force posture would be dictated by the ground realities.

"In certain places there will be fewer American resources. There'll be other places - I just talked about the threat from the Chinese Communist Party, so now threats to India, threats to Vietnam, threats to Malaysia, Indonesia, South China Sea challenges, the Philippines," he said.

"To the extent that that changed, the difference in what the US decided to do impacts adversely a threat some place, it may be that other nations need to step up and take responsibility for their own defense in ways that they hadn't done previously. So, we want to do this in full consultation with all of our partners all around the world, and certainly our friends in Europe," Mr Pompeo said.

President Trump is being criticised for reducing troops from Germany. His critics say that this will increase the threat from Russia to Europe.

Mike Pompeo, however, did not agree with that argument.

It has been a long time since there has been a strategic review of our force posture all across the world. The US undertook that starting about 2.5 years ago, whether that was our forces in Africa, our forces in Asia, the force we have in the Middle East and in Europe, he said.

"We began to say these are often decisions that were made in a different time. Should we reallocate those a different way? Should we have a different composition of those forces? Everyone always wants to talk about ground troops. I get it. I was a young tank officer. You described that. There's nothing I like as much as a good M1 tank.

"But it's often the case that the capacity to deter Russia or other adversaries isn''t determined any longer by just having a bunch of folks garrisoned someplace. So, we really went to back fundamentally relook, what is the nature of the conflict, what''s the nature of the threat, and how should we allocate our resources, whether that''s our resources in the intelligence community, our resources from the Air Force or the Marines and Army," Mr Pompeo said.

Last week, Mike Pompeo criticised the Chinese Army for "escalating" the border tension with India and militarising the strategic South China Sea. He also described the ruling Communist Party of China (CPC) as a "rogue actor".

"Our broad set of allocation of security apparatus, our ability to counter cyber threats, how do we allocate them? What''s the best way to do this? And the decision that you see the president made with respect to Germany is an outcome from a collective set of decisions about how we''re going to posture our resources around the world," said the top American diplomat on Thursday.

Changes in force posture is being taken in consultations with allies and friends, Mr Pompeo said.

"President Trump has spoken to this. (Defense) Secretary (Mark) Esper will be in London today and in Brussels tomorrow. We''ll talk about our plan and how we''re thinking about delivering it," he said.

"But you should understand this, and I hope our European partners will understand this as well. When you see what we ultimately conclude, how we ultimately deliver on the statements of the president made, that they''re aimed squarely at what we believe to be democracies'' fundamental interest and certainly America's most fundamental interest," Mr Pompeo said.

Earlier this month, Mike Pompeo had said that China's actions, be it on the India border, or in Hong Kong or in the South China Sea, were part of the behaviour of the ruling Communist Party in Beijing in the recent past.

China has been fast expanding military and economic influence in the Indo-Pacific region, triggering concern in various countries of the region and beyond.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.
