Nirav Modi's judicial custody extended till Sept 19 by London court

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.

Nakhon Ratchasima, Feb 9: The Thai soldier who killed at least 20 people and holed up in a mall overnight was shot dead Sunday morning by commandos, ending a near-17-hour ordeal which left dozens wounded and stunned the country.

It was unclear how many people remained trapped inside the Terminal 21 mall in Nakhon Ratchasima -- also known as Korat -- where the gunman held out through the night, armed with assault weapons stolen from his barracks.

Volleys of gunfire rang out as the siege ran into dawn, hours after Thai security services stormed the ground floor and freed scores of stunned, terrified shoppers from a bloody rampage that the gunman -- a junior army officer identified as Sergeant-Major Jakrapanth Thomma -- had relayed via Facebook posts.

"He was shot dead thirty minutes ago" (0200 GMT), chief of the Crime Suppression Division Jirabhob Bhuridej told AFP.

Commandos from elite Thai police units killed the gunman, a police spokesman added, after an operation involving hundreds of security personnel.

"The official death toll is 20 and wounded 42... nine are in surgery," Narinrat Pitchayakamin, a Korat doctor told reporters, revising down an initial death toll of 21.

But it was unclear if there were more victims inside the multi-level complex which was packed with Saturday shoppers when the gunman stormed in.

A fleet of ambulances left the front of the complex and forensic police poured into the grim crime scene, shortly before the gunman's death was confirmed.

The night was peppered with heavy exchanges of gunfire and sporadic evacuations.

A police officer who took part in a raid to flush out the gunman died, according to deputy prime minister Anutin Charnvirakul. "He had been hit and unfortunately, he couldn't make it," said Anutin.

Shocked evacuees recounted how an ordinary Saturday shopping day at the busy mall descended into horror as the gunman entered.

"It was like a dream... I'm grateful I survived," Sottiyanee Unchalee, 48, told AFP, explaining she hid in the toilet of a gym inside the mall as she heard the gunfire.

"I'm so sorry for those who died... (and) the people still trapped inside."

Stolen weapons

Jakrapanth relayed his shooting spree through Facebook posts which charted the attack from the army barracks in the city to the mall, where an unknown number of shoppers remained trapped.

A volunteer rescue worker recounted a bloody scene of horror after his team carried four corpses to the hospital.

"I've never seen anything like this," Peerapong Chatadee told AFP.

"I just feel so sad. He is a soldier, he should not have fired at unarmed people."

The bloodshed began Saturday afternoon when Jakrapanth shot three people -- among them at least one soldier -- at a senior officer's house and then at the nearby army barracks, before driving an army vehicle to the town centre.

There the gunman used weapons stolen from the military arsenal to unleash carnage in the town centre.

He "used a machine gun and shot innocent victims resulting in many injured and dead", said police spokesman Krissana Pattanacharoen.

Throughout the day, Jakrapanth posted images of himself and wrote several posts on his Facebook page as the attack unfolded.

In one Facebook video -- since deleted -- the assailant, wearing an army helmet, filmed from an open-top jeep, saying, "I'm tired... I can't pull my finger anymore" as he made a trigger symbol with his hand.

There were also photos of a man in a ski mask holding up a pistol.

A Facebook spokesperson said: "We have removed the gunman's accounts from our services and will work around the clock to remove any violating content related to this attack as soon as we become aware of it."

The city is home to one of the largest barracks in Thailand, a country where the military is enmeshed in politics and society.

The nation also has one of the highest rates of gun ownership in the world, and several shootings at courthouses last year renewed concern about gun violence.

Beijing, Jan 23: China is putting on lockdown a city of 11 million people considered the epicenter of the new coronavirus outbreak that has killed 17 and infected nearly 600 people, as health authorities around the world work to prevent a global pandemic.

The previously unknown coronavirus strain is believed to have emerged late last year from illegally traded wildlife at an animal market in the central Chinese city of Wuhan. Cases have been detected as far away as the United States, stoking fears the virus is already spreading worldwide.

Wuhan's local government said it would shut down all urban transport networks and suspend outgoing flights from the city as of 10 a.m. (0200 GMT) Thursday, state media reported, adding that the government is urging citizens to not leave the city in the absence of special circumstances.

Contrasting with its secrecy over the 2002-03 Severe Acute Respiratory Syndrome (SARS), which killed nearly 800 people, China's communist government has this time given regular updates to try to avoid panic as millions of people travel for the Chinese Lunar New Year holiday.

Chinese authorities have confirmed 571 cases and 17 deaths as of end-Wednesday, state television reported on Thursday. There are eight other known cases around the world - Thailand has confirmed four cases, while the United States, Taiwan, South Korea and Japan have each reported one.

Vice Premier Sun Chunlan said during a visit to Wuhan that authorities needed to be open about the spread of the virus and their efforts to contain it, the official Xinhua news agency reported on Thursday, comments likely to reassure global health experts.

After a meeting at its Geneva headquarters on Wednesday, the World Health Organization (WHO) said it would decide on Thursday whether to declare the outbreak a global health emergency, which would step up the international response.

If it does so, it will be the sixth international public health emergency to be declared in the last decade.

WHO Director-General Tedros Adhanom Ghebreyesus told reporters in Geneva that China's actions so far were "very strong" but called in Beijing to take "more and significant measures to limit or minimise the international spread".

"We stressed to them that by having a strong action not only they will control the outbreak in their country but they will also minimise the chances of this outbreak spreading internationally. So they recognise that," he said.

A senior U.S. State Department official also called on China to "play a bigger role in global health so they taking more and significant measures to limit or minimise the international spread".

"The lack of transparency in the past, especially with SARS ... gives us concern that that may be the case here," the official said, adding however that there were "positive signs that they have taken action in Wuhan".

Fears of a pandemic initially spooked markets but they regained their footing on Wednesday, with investors citing the robust response from authorities as reassuring.

VIRUS SPREADING

The outbreak began in Wuhan, a major transportation hub as well as central China's main industrial and commercial centre, and has now spread to other major population centers including Beijing, Shanghai and Hong Kong.

There is no known cure for the virus. Symptoms include fever, difficulty in breathing and cough, similar to many other respiratory illnesses, and can cause pneumonia.

Chinese authorities are still investigating the origins of the virus, though they confirmed the outbreak began at a market in Wuhan with illegal wildlife transactions and that it can spread from one person to another via respiratory transmission. Among confirmed patients are 15 medical workers, further adding to worries about a possible global pandemic.

Many Chinese were canceling trips, buying face masks, avoiding public places such as cinemas and shopping centers, and even turning to an online plague simulation game as a way to cope.

Airports globally stepped up screening passengers from China and the European Centre for Disease Control and Prevention (ECDC) said in a risk assessment that further global spread of the virus was likely.

Britain joined other countries including Australia in advising citizens against all but essential travel to Wuhan.
