Nawaz Sharif, Daughter Arrive In Lahore After Jail Sentence Is Suspended

Washington, Jun 9: When epidemiologists talked about "flattening the curve," they probably didn't mean it this way: the US hit its peak coronavirus caseload in April, but since that time the graph has been on a seemingly unending plateau.

That's unlike several other hard-hit countries which have successfully pushed down their numbers of new cases, including Spain and Italy, which now have bell-shaped curves.

Experts say the prolonged nature of the US epidemic is the result of the cumulative impact of regional outbreaks, as the virus that started out primarily on the coasts and in major cities moves inward.

Layered on top of that are the effects of lifting lockdowns in parts of the country that are experiencing rising cases, as well as a lapse in compliance with social distancing guidelines because of economic hardship, and in some cases a belief that the threat is overstated.

"The US is a large country both in geography and population, and the virus is at very different stages in different parts of the country," Tom Frieden, a former director of the Centers for Disease Control and Prevention told AFP.

The US saw more than 35,000 new cases for several days in April. While that figure has declined, it has still been exceeding 20,000 regularly in recent days.

By contrast, Italy was regularly hitting more than 5,000 cases per day in March but is currently experiencing figures in the low hundreds.

"We did not act quickly and robustly enough to stop the virus spreading initially, and data indicate that it travelled from initial hotspots along major transport routes into other urban and rural areas," added Frieden, now CEO of the non-profit Resolve to Save Lives.

To wit: the East Coast states of New York, New Jersey and Massachusetts accounted for about 50 percent of all cases until about a month or so ago -- but now the geographic footprint of the US epidemic has shifted to the Midwest and southeast, including Florida.

Another key problem, said Jennifer Nuzzo, an epidemiologist at Johns Hopkins, is that the United States is still not doing enough testing, contact tracing and isolation.

After coming late to the testing party -- for reasons ranging from technical issues to regulatory hurdles -- the US has now conducted more COVID-19 tests than any other country.

It even has one of the highest per capita rates per country of 62 per 1,000 people, according to the website ourworldindata.org -- better than Germany (52 per 1,000) and South Korea (20 per 1,000).

But according to Nuzzo, these numbers are misleading, because "the amount of testing that a country should do should be scaled to the size of its epidemic.

"The United States has the largest epidemic in the world so obviously we need to do a lot more testing than any other country."

For Johns Hopkins, the more important metric is the positivity rate -- that is, out of all tests conducted, how many came back positive for COVID-19.

As of June 7, the United States had an average daily positivity rate of 14 percent, well above the World Health Organization guideline of 5 percent over two weeks before social distancing guidelines should be relaxed.

By contrast, Germany, which has tested far fewer people in relation to its population, has a positivity rate of 5 percent.

Even if testing were scaled up, carrying out tests in of itself does very little good without the next steps -- finding out who was exposed and then asking them to isolate.

Here also, too many US states are lagging woefully behind.

Texas, which is experiencing a surge in cases after relaxing its lockdown, is a case in point. The state targeted hiring a modest 4,000 tracers by June, but according to local reports is still more than a thousand shy of even that goal.

Opt-in app based efforts have also been slow to get off the ground.

Then there is the fact that some people are growing tired of lockdowns, while others don't have the economic luxury of being able to stay home for prolonged periods.

The government sent some 160 million Americans a single stimulus check of up to $1,200 back in April but it's not clear whether more will be forthcoming.

Still others, particularly in so-called red states under Republican leadership, have chafed under restrictions and mask-wearing guidelines that they see as an affront to their personal freedom.

"The US is kind of on the extreme of the individual liberty side," Sten Vermund, dean of the Yale School of Public Health, told AFP.

Part of this has to do with mixed messaging from Republican leaders, including President Donald Trump, said Nuzzo.

"We have had at the highest political level an assertion that this is a situation that's been overblown, and that maybe certain protective behaviors are not necessary," she said.

More recently, tens of thousands of people across the country have taken to the streets to protest the killing on an unarmed black man by police, risking coronavirus infection to demonstrate against the public health threat of racialized state violence.

Jan 24: India’s economy appears to be shaking off a slump, as activity in the services and manufacturing sectors expanded for a second straight month in December.

The needle on a gauge measuring so-called animal spirits signaled the economy may be taking a turn for the better, as five of the eight high-frequency indicators tracked by Bloomberg News came in stronger last month. The dial was last at the current position in August.

“Animal spirits” is a term coined by British economist John Maynard Keynes to refer to investors’ confidence in taking action, and the gauge uses the three-month weighted average to smooth out volatility in the single-month numbers.

The nascent recovery would need a helping hand, with expectations building that Finance Minister Nirmala Sitharaman will provide some stimulus when she presents the budget Feb. 1. Official forecasts show the economy is set to expand at 5% in the year ending March 2020 -- the weakest pace in more than a decade.

Here are the details of the dashboard:

Business Activity

The dominant services index rose to the highest level in five months in December as improving new work orders helped boost activity. The seasonally adjusted Markit India Services PMI index climbed to 53.3 from 52.7 in November, helping post a strong end to the calendar year.

India’s manufacturing PMI also rose -- to 52.7 from 51.2 a month ago -- boosted by the fastest increase in new orders since July. A reading above 50 means expansion while anything below that signals contraction.

The uptick in business confidence was accompanied by a rise in inflationary pressures, the survey showed. That trend may keep monetary policy makers from resuming interest-rate cuts anytime soon, leaving most of the heavy-lifting to boost growth with the government.

“The relative stability in macro indicators over the past two months suggests that the worst is behind, but the recovery is likely to be prolonged,” said Teresa John, an economist at Nirmal Bang Equities Pvt. in Mumbai. “Still, sluggish growth and rising inflation indicate that India may well remain in stagflation for most of 2020.”

Exports

Exports remained a laggard, falling 1.8% in December from a year ago. The drag was mainly because of a fall in export of engineering goods, which constitute a third of India’s non-oil exports.

Capital goods imports continued to contract and was lower by 16.5% year-on-year in December after a 22% drop in November. This was the seventh consecutive month of continuous decline, underscoring the weakness in the capex cycle, according to IDFC First Bank.

Consumer Activity

Weakness in demand for passenger vehicles persisted, with local sales falling 1.2% in December from a year ago, according to the Society of Indian Automobile Manufacturers. That capped the worst yearly passenger vehicle sales on record. A Nielsen study on demand for fast-moving consumer goods showed volume growth dropped to 3.5% in the last quarter of 2019 from 3.9% in the same period of 2018.

Funding conditions held out hope, showing considerable improvement in December, according to the Citi India Financial Conditions Index. Credit growth remained tardy though, with demand for loans rising at a slower 7.1% pace from a year ago compared with a nearly 8% growth in November.

Industrial Activity

Industrial output rose for the first time in four months in November. The pick up was broad-based, led by mining, manufacturing and electricity. Mining and manufacturing, in particular, posted a second month of sequential growth. Production of consumer goods also rose after a few months of contraction.

The index of eight core infrastructure industries, which feeds into the index of industrial production, however, declined 1.5% in November from a year ago -- the fourth straight month of contraction. That was on account of shrinking production of electricity, steel, coal, natural gas and crude oil. Both the core sector and industrial output numbers are reported with a one-month lag.

Kensington (United States), May 20: The world cut its daily carbon dioxide emissions by 17% at the peak of the pandemic shutdown last month, a new study found.

But with life and heat-trapping gas levels inching back toward normal, the brief pollution break will likely be “a drop in the ocean" when it comes to climate change, scientists said.

In their study of carbon dioxide emissions during the coronavirus pandemic, an international team of scientists calculated that pollution levels are heading back up — and for the year will end up between 4% and 7% lower than 2019 levels.

That's still the biggest annual drop in carbon emissions since World War II.

It'll be 7% if the strictest lockdown rules remain all year long across much of the globe, 4% if they are lifted soon.

For a week in April, the United States cut its carbon dioxide levels by about one-third.

China, the world's biggest emitter of heat-trapping gases, sliced its carbon pollution by nearly a quarter in February, according to a study Tuesday in the journal Nature Climate Change. India and Europe cut emissions by 26% and 27% respectively.

The biggest global drop was from April 4 through 9 when the world was spewing 18.7 million tons (17 million metric tons) of carbon pollution a day less than it was doing on New Year's Day.

Such low global emission levels haven't been recorded since 2006. But if the world returns to its slowly increasing pollution levels next year, the temporary reduction amounts to ''a drop in the ocean," said study lead author Corinne LeQuere, a climate scientist at the University of East Anglia.

“It's like you have a bath filled with water and you're turning off the tap for 10 seconds," she said.

By April 30, the world carbon pollution levels had grown by 3.3 million tons (3 million metric tons) a day from its low point earlier in the month. Carbon dioxide stays in the air for about a century.

Outside experts praised the study as the most comprehensive yet, saying it shows how much effort is needed to prevent dangerous levels of further global warming.

“That underscores a simple truth: Individual behavior alone ... won't get us there,” Pennsylvania State University climate scientist Michael Mann, who wasn't part of the study, said in an email.

“We need fundamental structural change.”

If the world could keep up annual emission cuts like this without a pandemic for a couple decades, there's a decent chance Earth can avoid warming another 1.8 degrees (1 degree Celsius) of warming from now, study authors said. But getting the type of yearly cuts to reach that international goal is unlikely, they said.

If next year returns to 2019 pollution levels, it means the world has only bought about a year's delay in hitting the extra 1.8 degrees (1 degree Celsius) of warming that leaders are trying to avoid, LeQuere said. That level could still occur anywhere from 2050 to 2070, the authors said.

The study was carried out by Global Carbon Project, a consortium of international scientists that produces the authoritative annual estimate of carbon dioxide emissions. They looked at 450 databases showing daily energy use and introduced a measurement scale for pandemic-related societal “confinement” in its estimates.

Nearly half the emission reductions came from less transportation pollution, mostly involving cars and trucks, the authors said. By contrast, the study found that drastic reductions in air travel only accounted for 10% of the overall pollution drop.

In the US, the biggest pollution declines were seen in California and Washington with plunges of more than 40%.
