Pak warns of new refugee crisis due to Indian govt's policies

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.

New York, Jan 10: The US's National Transportation Safety Board (NTSB) announced that it has accepted an invitation from Tehran to participate in its investigation into the crash of a Ukrainian plane amid speculations that an Iranian missile might have brought down the plane.

The federal agency said in a statement on Thursday that the Iran Civil Aviation Organization has notified them that they could take part in the investigation of the plane crash that occurred shortly after taking off from Tehran on Wednesday, killing all 176 people on board, reports the Efe news.

"The NTSB has designated an accredited representative to the investigation of the crash," said the independent US government agency tasked with investigating transport accidents.

Since the aircraft was a US-made Boeing 737-800, international regulations allow Washington to be a part of the accident investigation.

However, it remains unclear to what extent the NTSB representative will be able to play an active role in the probe, as US sanctions complicate cooperation with Iran, and the two countries have no diplomatic relations.

The NTSB announcement came hours after US intelligence sources told several media outlets that the Kiev-bound Ukrainian International Airlines (UIA) flight 752 could have been accidentally shot down by an Iranian missile.

Canadian Prime Minister Justin Trudeau later confirmed that his government had "evidence" indicating that the aircraft "was shot down by an Iranian surface to air missile", although he added it may have been unintentional.

The accident occurred on the same day after Iran launched more than a dozen ballistic missiles at two US military bases in Iraq, in retaliation for the killing of Iranian Major General Qasem Soleimani in an American drone attack in Baghdad on January 3.

However, the Iranian authorities have denied that they had accidentally shot down the plane and claimed the accusations were a part of a psychological warfare campaign against Tehran.

Iranian foreign ministry spokesman Abbas Mousavi said they welcomed the presence of experts from countries whose citizens have died in the tragic accident, and requested Trudeau and any other government to provide any information they had regarding the crash.

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.
