China says trade war 'has not made America great again'

Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

Moscow, Jun 7: OPEC, Russia and allies agreed on Saturday to extend record oil production cuts until the end of July, prolonging a deal that has helped crude prices double in the past two months by withdrawing almost 10% of global supplies from the market.

The group, known as OPEC+, also demanded countries such as Nigeria and Iraq, which exceeded production quotas in May and June, compensate with extra cuts in July to September.

OPEC+ had initially agreed in April that it would cut supply by 9.7 million barrels per day (bpd) during May-June to prop up prices that collapsed due to the coronavirus crisis. Those cuts were due to taper to 7.7 million bpd from July to December.

“Demand is returning as big oil-consuming economies emerge from pandemic lockdown. But we are not out of the woods yet and challenges ahead remain,” Saudi Energy Minister Prince Abdulaziz bin Salman told the video conference of OPEC+ ministers.

Benchmark Brent crude climbed to a three-month high on Friday above $42 a barrel, after diving below $20 in April. Prices still remain a third lower than at the end of 2019.

“Prices can be expected to be strong from Monday, keeping their $40 plus levels,” said Bjornar Tonhaugen from Rystad Energy.

Saudi Arabia, OPEC’s de facto leader, and Russia have to perform a balancing act of pushing up oil prices to meet their budget needs while not driving them much above $50 a barrel to avoid encouraging a resurgence of rival U.S. shale production.

It was not immediately clear whether Saudi Arabia, the United Arab Emirates and Kuwait would extend beyond June their additional, voluntary cuts of 1.18 million bpd, which are not part of the deal.

BULGING INVENTORIES

The April deal was agreed under pressure from U.S. President Donald Trump, who wants to avoid U.S. oil industry bankruptcies.

Trump, who previously threatened to pull U.S. troops out of Saudi Arabia if Riyadh did not act, spoke to the Russian and Saudi leaders before Saturday’s talks, saying he was happy with the price recovery.

While oil prices have partially recovered, they are still well below the costs of most U.S. shale producers. Shutdowns, layoffs and cost cutting continue across the United States.

“I applaud OPEC-plus for reaching an important agreement today which comes at a pivotal time as oil demand continues to recover and economies reopen around the world,” U.S. Energy Secretary Dan Brouillette wrote on Twitter after the extension.

As global lockdowns ease, oil demand is expected to exceed supply sometime in July but OPEC has yet to clear 1 billion barrels of excess oil inventories accumulated since March.

Rystad’s Tonhaugen said Saturday’s decisions would help OPEC reduce inventories at a rate of 3 million to 4 million bpd in July-August. “The quicker stocks fall, the higher prices will get,” he said.

Nigeria’s petroleum ministry said Abuja backed the idea of compensating for its excessive output in May and June.

Iraq, with one of the worst compliance rates in May, agreed to extra cuts although it was not clear how Baghdad would reach agreement with oil majors on curbing Iraqi output.

Iraq produced 520,000 bpd above its quota in May, while overproduction by Nigeria was 120,000 bpd, Angola’s was 130,000 bpd, Kazakhstan’s was 180,000 bpd and Russia’s was 100,000 bpd, OPEC+ data showed.

OPEC+’s joint ministerial monitoring committee, known as the JMMC, will meet monthly until December to review the market, compliance and recommend levels of cuts. JMMC’s next meeting is scheduled for June 18.

OPEC and OPEC+ will hold their next scheduled meetings on Nov. 30-Dec. 1.

May 30: Warning of the tightrope walk ahead as governments battle the coronavirus crisis, Nobel laureate Peter Charles Doherty has expressed concern about densely populated countries such as India relaxing lockdown norms while also describing a complete shutdown as “an economic and social impossibility”.

The Australian immunologist, who cautioned that the number of COVID-19 cases will rise in the coming days, said the earliest time frame for an effective vaccine “going into large numbers of people” is nine to 12 months.

"If all goes well with testing, we could know if some of the candidate vaccines are both safe and effective as early as September/October. Then, rolling a vaccine out will depend on the type of product and how quickly it can be made, put in vials and so forth," Doherty told PTI in an email interview from Melbourne.

The novel coronavirus, he added, does not change fast like influenza and, from what is known so far, “the same vaccine should work everywhere”.

Doherty, who is with the Department of Microbiology and Immunology at the Doherty Institute, University of Melbourne, won the Nobel Prize for Medicine in 1996 for his discovery of how the body’s immune system distinguishes virus-infected cells from normal ones.

Discussing the lockdown, he said, "If it was purely a matter of hard science, everywhere should stay locked down. But that’s pretty much an economic and social impossibility.”

The expectation, he said, is the numbers will rise and limiting spread will depend on people acting responsibly and the capacity for rapid response and extensive contact testing.

“And in a densely populated country like India I think that it will be very difficult," the scientist said.

Several countries, including India, began relaxing lockdown norms in mid-May despite the WHO’s warning about a second wave. India’s lockdown began on March 25 and has since been extended. The fourth phase ends on Sunday.

Asked whether there are any alternatives to a lockdown, the 79-year-old said, "There is no other option other than closing borders. South Korea, for example, conducted massive, intensive testing and contact tracing in a wealthy country with a very disciplined population. Otherwise, not till we have effective vaccines."

He added that he personally doesn’t see the point of closing borders for people coming in if there’s already a high incidence of disease in the community, “unless it’s to avoid the need to care for them and use scarce hospital beds".

According to Doherty, the coronavirus "is a new virus which has come straight out of nature".

“It (the virus) has moved so rapidly across the world because of people travelling on international planes as well as tourist ships," he added.

The immunologist also warned against the use of hydroxychloroquine to treat COVID-19, and said current and planned trials of the anti-malaria drug should be stopped.

“My understanding is that the use of the drug in severe disease is definitely contra-indicated, but it’s not yet clear whether, if taken under medical supervision, it could have some useful effect if taken early on, or as a preventive. Those trials just haven’t been done properly," Doherty noted.

The Indian Council of Medical Research (ICMR) has backed the use of hydroxychloroquine as a preventive against COVID-19 even after the WHO suspended clinical trials of the drug citing safety concerns.

Asked whether plasma therapy can be an effective treatment for COVID-19, Doherty said, "We lack good properly controlled trials but, especially if the plasma has been tested for antibody levels and there’s evidence of good activity, it could be helpful. If I had the disease and was offered plasma therapy I would certainly accept, but I would not take hydroxychloroquine."

Doherty is also very optimistic about herd immunity developing against the SARS-CoV-2 infection.

"We think that (herd immunity) will cut in and have an obvious effect when, say, 60 per cent of people have been infected. Best hope is to boost herd immunity with a vaccine," he stated.

Herd immunity is a form of indirect protection from infectious disease that occurs when a large percentage of a population has become immune to an infection, whether through vaccination or previous infections.

The number of COVID-19 cases have crossed 5.9 million and the fatalities 3,65,000, according to the Johns Hopkins University on Saturday. 

In India, the death toll has risen to 4,971 and the number of cases to 1,73,763, according to the Union Health Ministry on Saturday.

Several states, including Bihar, Uttar Pradesh, Madhya Pradesh, Jharkhand and Chhattisgarh, have reported a rise in number since lockdown norms were relaxed in early May and migrant workers reached home.

In Uttar Pradesh, for instance, the number of infections rose from around 3,000 on May 4 to 6,532 on May 26. Similarly, Bihar’s numbers increased from around 500 to over 2,700 in the period.
