Suspected debris from missing Malaysian jet may have sunk: Australia

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.

United Nations, Apr 2: The global economy could shrink by up to one per cent in 2020 due to the coronavirus pandemic, a reversal from the previous forecast of 2.5 per cent growth, the UN has said, warning that it may contract even further if restrictions on the economic activities are extended without adequate fiscal responses.

The analysis by the UN Department of Economic and Social Affairs (DESA) said the COVID-19 pandemic is disrupting global supply chains and international trade. With nearly 100 countries closing national borders during the past month, the movement of people and tourism flows have come to a screeching halt.

"Millions of workers in these countries are facing the bleak prospect of losing their jobs. Governments are considering and rolling out large stimulus packages to avert a sharp downturn of their economies which could potentially plunge the global economy into a deep recession. In the worst-case scenario, the world economy could contract by 0.9 per cent in 2020," the DESA said, adding that the world economy had contracted by 1.7 per cent during the global financial crisis in 2009.

It added that the contraction could be even higher if governments fail to provide income support and help boost consumer spending.

The analysis noted that before the outbreak of the COVID-19, world output was expected to expand at a modest pace of 2.5 per cent in 2020, as reported in the World Economic Situation and Prospects 2020.

Taking into account rapidly changing economic conditions, the UN DESA's World Economic Forecasting Model has estimated best and worst-case scenarios for global growth in 2020.

In the best-case scenario with moderate declines in private consumption, investment and exports and offsetting increases in government spending in the G-7 countries and China global growth would fall to 1.2 per cent in 2020.

"In the worst-case scenario, the global output would contract by 0.9 per cent instead of growing by 2.5 per cent in 2020," it said, adding that the scenario is based on demand-side shocks of different magnitudes to China, Japan, South Korea, the US and the EU, as well as an oil price decline of 50 per cent against our baseline of USD 61 per barrel.

The severity of the economic impact will largely depend on two factors - the duration of restrictions on the movement of people and economic activities in major economies; and the actual size and efficacy of fiscal responses to the crisis.

A well-designed fiscal stimulus package, prioritising health spending to contain the spread of the virus and providing income support to households most affected by the pandemic would help to minimise the likelihood of a deep economic recession, it said.

According to the forecast, lockdowns in Europe and North America are hitting the service sector hard, particularly industries that involve physical interactions such as retail trade, leisure and hospitality, recreation and transportation services. Collectively, such industries account for more than a quarter of all jobs in these economies.

The DESA said as businesses lose revenue, unemployment is likely to increase sharply, transforming a supply-side shock to a wider demand-side shock for the economy.

Against this backdrop, the UN-DESA is joining a chorus of voices across the UN system calling for well-designed fiscal stimulus packages which prioritize health spending and support households most affected by the pandemic.

Urgent and bold policy measures are needed, not only to contain the pandemic and save lives, but also to protect the most vulnerable in our societies from economic ruin and to sustain economic growth and financial stability, Under-Secretary-General for Economic and Social Affairs Liu Zhenmin said.

The analysis also warns that the adverse effects of prolonged economic restrictions in developed economies will soon spill over to developing countries via trade and investment channels.

A sharp decline in consumer spending in the European Union and the United States will reduce imports of consumer goods from developing countries.

Developing countries, particularly those dependent on tourism and commodity exports, face heightened economic risks. Global manufacturing production could contract significantly, and the plummeting number of travellers is likely to hurt the tourism sector in small island developing States, which employs millions of low-skilled workers, it said.

Meanwhile, the decline in commodity-related revenues and a reversal of capital flows are increasing the likelihood of debt distress for many nations. Governments may be forced to curtail public expenditure at a time when they need to ramp up spending to contain the pandemic and support consumption and investment.

UN Chief Economist and Assistant Secretary-General for Economic Development Elliot Harris said the collective goal must be a resilient recovery which puts the planet back on a sustainable track. We must not lose sight how it is affecting the most vulnerable population and what that means for sustainable development, he said.

The alarms raised by UN-DESA echo another report, released on March 31, in which UN experts issued a broad appeal for a large-scale, coordinated, comprehensive multilateral response amounting to at least 10 per cent of global gross domestic product (GDP).

According to estimates by the Johns Hopkins University, confirmed coronavirus cases across the world now stand at over 932,600 and over 42,000 deaths.

Singapore, Mar 23: Oil prices fell at the open in Asia on Monday after a trillion-dollar Senate proposal to help the coronavirus-hit American economy was defeated and death tolls soared across Europe and the US.

US benchmark West Texas Intermediate initially tumbled more than three percent but then pulled back some ground to trade 1.5 percent lower, at $22 a barrel.

Brent crude, the international benchmark, fell 4.9 percent to $25 a barrel.

Prices have fallen to multi-year lows in recent weeks as lockdowns and travel restrictions to fight the virus hit demand, and top producers Saudi Arabia and Russia engage in a price war.

The latest drop came after a trillion-dollar Senate proposal to rescue the US economy was defeated after receiving zero support from Democrats, and with five Republicans absent from the chamber because of virus-related quarantines.

The bill had proposed funding for American families, thousands of shuttered or suffering businesses and the nation's critically under-equipped hospitals.

Coronavirus deaths soared across Europe and the United States at the weekend despite heightened restrictions.

The death toll from the virus -- which has upended lives and closed businesses and schools across the planet -- surged to more than 14,300 Sunday, according to an AFP tally.

AxiCorp chief markets strategist Stephen Innes said that "total demand devastation" had set it.

"Oil markets collapsed out of the gate this morning as prices react... to stringent containment lockdown measures," he said.
