Wuhan woman with no symptoms infects five relatives with coronavirus: Scientists

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, Apr 21: Oil prices plunged below zero on Monday as demand for energy collapses amid the coronavirus pandemic and traders don't want to get stuck owning crude with nowhere to store it.

Stocks were also slipping on Wall Street in afternoon trading, with the S&P 500 down 0.9%, but the market's most dramatic action was by far in oil, where benchmark U.S. crude for May delivery plummeted to negative $3.70 per barrel, as of 2:15 pm. Eastern time.

Much of the drop into negative territory was chalked up to technical reasons — the May delivery contract is close to expiring so it was seeing less trading volume, which can exacerbate swings. But prices for deliveries even further into the future, which were seeing larger trading volumes, also plunged.

Demand for oil has collapsed so much due to the coronavirus pandemic that facilities for storing crude are nearly full.

Tanks could hit their limits within three weeks, according to Chris Midgley, head of analytics at S&P Global Platts.

Benchmark U.S. crude oil for June delivery, which shows a more ”normal” price, fell 14.8% to $21.32 per barrel, as factories and automobiles around the world remain idled. Big oil producers have announced cutbacks in production in hopes of better balancing supplies with demand, but many analysts say it's not enough.

“Basically, bears are out for blood,” analyst Naeem Aslam of Avatrade said in a report. “The steep fall in the price is because of the lack of sufficient demand and lack of storage place given the fact that the production cut has failed to address the supply glut.”

Halliburton swung between gains and sharp losses, even though it reported stronger results for the first three months of 2020 than analysts expected. The oilfield engineering company said that the pandemic has created so much turmoil in the industry that it “cannot reasonably estimate” how long the hit will last. It expects a further decline in revenue and profitability for the rest of 2020, particularly in North America.

Brent crude, the international standard, was down $1.78 to $26.30 per barrel. .

In the stock market, the mild drops ate into some of the big gains made since late March, driven lately by investors looking ahead to parts of the economy possibly reopening as infections level off in hard-hit areas.

Pessimists have called the rally overdone, pointing to the severe economic pain sweeping the world and continued uncertainty about how long it will last.

The Dow Jones Industrial Average was down 364 points, or 1.5%, to 23,887. The Nasdaq was down 0.1%..

More gains from companies that are winners in the new stay-at-home economy helped limit the market's losses Amazon rose 1.4%, and Netflix jumped 3.8% as people shut in at home buy staples and look to fill their time. Clorox likewise rose toward a new record and was up 1% as households and businesses that remain open look to stay clean.

In Tokyo the Nikkei 225 fell 1.1% after Japan reported that its exports fell nearly 12% in March from a year earlier as the pandemic hammered demand in its two biggest markets, the U.S. and China.

The Hang Seng index in Hong Kong lost 0.2%, and South Korea's Kospi fell 0.8%.

European markets were modestly higher The German DAX was up 0.5%, the French CAC 40 was up 0.7% and the FTSE 100 in London gained 0.7%.

In a sign of continued caution in the market, Treasury yields remained extremely low. The yield on the 10-year Treasury slipped to 0.64% from 0.65% late Friday. It started the year near 1.90%. Bond yields drop when their prices rise, and investors tend to buy Treasurys when they're worried about the economy.

Stocks have been on a generally upward swing recently, and the S&P 500 just closed out its first back-to-back weekly gain since the market began selling off in February. Promises of massive aid for the economy and markets by the Federal Reserve and U.S. government ignited the rally, which sent the S&P 500 up as much as 28.5% since a low on March 23.

More recently, countries around the world have tentatively eased up on business-shutdown restrictions put in place to slow the spread of the virus.

But health experts warn the pandemic is far from over and new flareups could ignite if governments rush to allow ”normal” life to return prematurely.

The S&P 500 remains about 15% below its record high in February as millions more U.S. workers file for unemployment every week amid the shutdowns.

Many analysts also warn that a significant part of the recent recovery in stocks is due to the expectation among some investors that the economy will rebound sharply once economic quarantines are lifted. They're essentially predicting that a line chart of the economy will ultimately resemble the letter “V,” with a wild ride down but then a quick pivot to a vigorous recovery.

That may be to optimistic. “We caution that a U-shaped recovery is also quite likely,” where the economy bottoms out and stays at that low level for a while before recovering, strategists at Barclays warned in a recent report.

Without strong testing programs for COVID-19, businesses likely won't feel comfortable bringing back their full workforces for a while.

”With risk assets now overbought, the chance for a correction has increased,” Morgan Stanley strategists wrote in a report.

Minneapolis, Jul 23: The former Minneapolis police officer charged with murder in the death of George Floyd was charged Wednesday with multiple felony counts of tax evasion.

Derek Chauvin and his wife, Kellie May Chauvin, were each charged in Washington County with six counts of filing false or fraudulent tax returns for the tax years 2014 through 2019 and three counts of failing to file tax returns for 2016, 2017 and 2018.

Floyd, a Black man who was handcuffed, died May 25 after Chauvin, who is white, pressed his knee against Floyd's neck for nearly eight minutes as Floyd pleaded for air.

Chauvin is charged with second-degree murder, third-degree murder and manslaughter. He and three other officers who were at the scene were fired.

Chauvin is in custody on the charges in the Floyd case. Kellie Chauvin, who filed for divorce after Floyd's death, is not in custody.

Online court records didn't list attorneys for either in the tax evasion case, and calls to Kellie Chauvin did not go through.

Washington County Attorney Pete Orput said the investigation into the Chauvins was started in June by the Minnesota Department of Revenue and Oakdale Police Department.

Authorities allege in the criminal complaints that the Chauvins failed to file income tax returns and pay state income taxes, and that they underreported and underpaid taxes on income they earned from various jobs each year.

The complaints allege that they also failed to pay proper sales tax on a $100,000 BMW purchased in Minnesota in 2018.

Prosecutors say the Chauvins bought the car in Minnetonka but registered it in Florida, where they paid lower sales taxes.

Islamabad, Jun 24: A plane crash which killed 97 people in Pakistan last month was because of human error by the pilot and air traffic control, according to an initial report into the disaster released Wednesday.

The Pakistan International Airlines (PIA) plane came down among houses on May 22 after both engines failed as it approached Karachi airport, killing all but two people on board.

"The pilot as well as the controller didn't follow the standard rules," the country's aviation minister Ghulam Sarwar Khan said, announcing the findings in parliament.

He said the pilots had been discussing the coronavirus pandemic as they attempted to land the Airbus A320.

"The pilot and co-pilot were not focused and throughout the conversation was about coronavirus," Khan said.

The Pakistani investigation team, which included officials from the French government and the aviation industry, analysed data and voice recorders.

The minister said the plane was "100 percent fit for flying, there was no technical fault".

The county's deadliest aviation accident in eight years came days after domestic commercial flights resumed following a two-month coronavirus lockdown.

Many passengers were on their way to spend the Muslim holiday of Eid al-Fitr with loved ones.
