Excerpt:

NEW YORK (AP) — A new analysis of blood samples from 24,000 Americans taken early last year is the latest and largest study to suggest that the new coronavirus popped up in the U.S. in December 2019 — weeks before cases were first recognized by health officials.

The analysis is not definitive, and some experts remain skeptical, but federal health officials are increasingly accepting a timeline in which small numbers of COVID-19 infections may have occurred in the U.S. before the world ever became aware of a dangerous new virus erupting in China.

…..

The pandemic coronavirus emerged in Wuhan, China in late 2019. Officially, the first U.S. infection to be identified was a traveler — a Washington state man who returned from Wuhan on Jan. 15 and sought help at a clinic on Jan. 19.

CDC officials initially said the spark that started the U.S. outbreak arrived during a three-week window from mid-January to early February. But research since then — including some done by the CDC — has suggested a small number of infections occurred earlier.

The Science Suggests a Wuhan Lab Leak

Link: https://www.wsj.com/articles/the-science-suggests-a-wuhan-lab-leak-11622995184

Excerpt:

In gain-of-function research, a microbiologist can increase the lethality of a coronavirus enormously by splicing a special sequence into its genome at a prime location. Doing this leaves no trace of manipulation. But it alters the virus spike protein, rendering it easier for the virus to inject genetic material into the victim cell. Since 1992 there have been at least 11 separate experiments adding a special sequence to the same location. The end result has always been supercharged viruses.

A genome is a blueprint for the factory of a cell to make proteins. The language is made up of three-letter “words,” 64 in total, that represent the 20 different amino acids. For example, there are six different words for the amino acid arginine, the one that is often used in supercharging viruses. Every cell has a different preference for which word it likes to use most.

In the case of the gain-of-function supercharge, other sequences could have been spliced into this same site. Instead of a CGG-CGG (known as “double CGG”) that tells the protein factory to make two arginine amino acids in a row, you’ll obtain equal lethality by splicing any one of 35 of the other two-word combinations for double arginine. If the insertion takes place naturally, say through recombination, then one of those 35 other sequences is far more likely to appear; CGG is rarely used in the class of coronaviruses that can recombine with CoV-2.

In fact, in the entire class of coronaviruses that includes CoV-2, the CGG-CGG combination has never been found naturally. That means the common method of viruses picking up new skills, called recombination, cannot operate here. A virus simply cannot pick up a sequence from another virus if that sequence isn’t present in any other virus.

The Lab-Leak Theory: Inside the Fight to Uncover COVID-19’s Origins

Link: https://www.vanityfair.com/news/2021/06/the-lab-leak-theory-inside-the-fight-to-uncover-covid-19s-origins

Excerpt:

Wuhan is also home to China’s foremost coronavirus research laboratory, housing one of the world’s largest collections of bat samples and bat-virus strains. The Wuhan Institute of Virology’s lead coronavirus researcher, Shi Zhengli, was among the first to identify horseshoe bats as the natural reservoirs for SARS-CoV, the virus that sparked an outbreak in 2002, killing 774 people and sickening more than 8,000 globally. After SARS, bats became a major subject of study for virologists around the world, and Shi became known in China as “Bat Woman” for her fearless exploration of their caves to collect samples. More recently, Shi and her colleagues at the WIV have performed high-profile experiments that made pathogens more infectious. Such research, known as “gain-of-function,” has generated heated controversy among virologists.

…..

By spring of 2021, the debate over COVID-19’s origins had become so noxious that death threats were flying in both directions.

In a CNN interview on March 26, Dr. Redfield, the former CDC director under Trump, made a candid admission: “I am of the point of view that I still think the most likely etiology of this pathogen in Wuhan was from a laboratory, you know, escaped.” Redfield added that he believed the release was an accident, not an intentional act. In his view, nothing that happened since his first calls with Dr. Gao changed a simple fact: The WIV needed to be ruled out as a source, and it hadn’t been.

Intelligence on Sick Staff at Wuhan Lab Fuels Debate on Covid-19 Origin

Link: https://www.wsj.com/articles/intelligence-on-sick-staff-at-wuhan-lab-fuels-debate-on-covid-19-origin-11621796228?mod=djemalertNEWS

Excerpt:

Three researchers from China’s Wuhan Institute of Virology became sick enough in November 2019 that they sought hospital care, according to a previously undisclosed U.S. intelligence report that could add weight to growing calls for a fuller probe of whether the Covid-19 virus may have escaped from the laboratory.

The details of the reporting go beyond a State Department fact sheet, issued during the final days of the Trump administration, which said that several researchers at the lab, a center for the study of coronaviruses and other pathogens, became sick in autumn 2019 “with symptoms consistent with both Covid-19 and common seasonal illness.”

….

China’s National Health Commission and the WIV didn’t respond to requests for comment. Shi Zhengli, the top bat coronavirus expert at WIV, has said the virus didn’t leak from her laboratories. She told the WHO-led team that traveled to Wuhan earlier this year to investigate the origins of the virus that all staff had tested negative for Covid-19 antibodies and there had been no turnover of staff on the coronavirus team.

Marion Koopmans, a Dutch virologist on that team told NBC News in March that some WIV staff did fall sick in the autumn of 2019, but she attributed that to regular, seasonal sickness.

…..

It isn’t unusual for people in China to go straight to the hospital when they fall sick, either because they get better care there or lack access to a general practitioner. Covid-19 and the flu, while very different illnesses, share some of the same symptoms, such as fever, aches and a cough. Still, it could be significant if members of the same team working with coronaviruses went to hospital with similar symptoms shortly before the pandemic was first identified.

Long Slide Looms for World Population, With Sweeping Ramifications

Link: https://www.nytimes.com/2021/05/22/world/global-population-shrinking.html

Excerpt:

Like an avalanche, the demographic forces — pushing toward more deaths than births — seem to be expanding and accelerating. Though some countries continue to see their populations grow, especially in Africa, fertility rates are falling nearly everywhere else. Demographers now predict that by the latter half of the century or possibly earlier, the global population will enter a sustained decline for the first time.

A planet with fewer people could ease pressure on resources, slow the destructive impact of climate change and reduce household burdens for women. But the census announcements this month from China and the United States, which showed the slowest rates of population growth in decades for both countries, also point to hard-to-fathom adjustments.

The strain of longer lives and low fertility, leading to fewer workers and more retirees, threatens to upend how societies are organized — around the notion that a surplus of young people will drive economies and help pay for the old. It may also require a reconceptualization of family and nation. Imagine entire regions where everyone is 70 or older. Imagine governments laying out huge bonuses for immigrants and mothers with lots of children. Imagine a gig economy filled with grandparents and Super Bowl ads promoting procreation.

“A paradigm shift is necessary,” said Frank Swiaczny, a German demographer who was the chief of population trends and analysis for the United Nations until last year. “Countries need to learn to live with and adapt to decline.”

China’s People Problem Swings From Too Many to a ‘Decline That Sees No End’

Link: https://www.wsj.com/articles/chinas-people-problem-swings-from-too-many-to-a-decline-that-sees-no-end-11620903602

Excerpt:

Births in China plunged 18% in 2020, though Covid-19 may have played a part, and, if so, fewer newborns might arrive in 2021 as well.

China will remain enormous, but the figures signal a waning of the demographic trends that came to define its modern era, with its huge working-age population spurring 40-plus straight years of economic expansion. A drop in household size, for example, to 2.6 last year from 3.1 a decade earlier, highlights the effects of the birth restrictions since about 1980.

The challenge for China now is its shrinking working-age population versus its growing elderly one, represented by only 12 million annual births, a fractional number for such a populous country.

In the latest census, 63% of Chinese were ages 15 to 59, compared with 70% in 2010, while nearly 19% in 2020 were 60 years old or above, versus 13% a decade earlier.

Investigate the origins of COVID-19

Link: https://science.sciencemag.org/content/372/6543/694.1

Excerpt:

As scientists with relevant expertise, we agree with the WHO director-general (5), the United States and 13 other countries (6), and the European Union (7) that greater clarity about the origins of this pandemic is necessary and feasible to achieve. We must take hypotheses about both natural and laboratory spillovers seriously until we have sufficient data. A proper investigation should be transparent, objective, data-driven, inclusive of broad expertise, subject to independent oversight, and responsibly managed to minimize the impact of conflicts of interest. Public health agencies and research laboratories alike need to open their records to the public. Investigators should document the veracity and provenance of data from which analyses are conducted and conclusions drawn, so that analyses are reproducible by independent experts.

Top researchers are calling for a real investigation into the origin of covid-19

Link: https://www.technologyreview.com/2021/05/13/1024866/investigation-covid-origin-wuhan-china-lab-biologists-letter/

Excerpt:

Now, in a letter in the journal Science, 18 prominent biologists—including the world’s foremost coronavirus researcher—are lending their weight to calls for a new investigation of all possible origins of the virus, and calling on China’s laboratories and agencies to “open their records” to independent analysis.

“We must take hypotheses about both natural and laboratory spillovers seriously until we have sufficient data,” the scientists write.

The letter, which was organized by the Stanford University microbiologist David Relman and the University of Washington virologist Jesse Bloom, takes aim at a recent joint study of covid origins undertaken by the World Health Organization and China, which concluded that a bat virus likely reached humans via an intermediate animal and that a lab accident was “extremely unlikely.”

As World Runs Short of Workers, a Boost for Wages—and Inflation

Link: https://www.wsj.com/articles/as-world-runs-short-of-workers-a-boost-for-wagesand-inflation-11620824675

Graphic:

Excerpt:

The U.S. population grew 7% between 2010 and 2020, according to census results. The age breakdown isn’t yet available, but a smaller sample by the Census Bureau and the Bureau of Labor Statistics shows that the working-age population — those 16 to 64 — grew just 3.3%. Because the share of those people working or looking for work has shrunk, the working-age labor force grew only 2%, and actually shrank last year. Some of those missing workers will return when the virus recedes. But many won’t: Baby boomer retirements have soared.

Reversing this move would require either a dramatic increase in births, which has eluded countries with more-family-friendly policies, or immigration, which is politically hard.

The demographic squeeze is far more severe in China, which admits almost no immigrants and for years limited families to one child. Tuesday, authorities said the population in China had grown just 5.4% in the past decade. The working-age population — those 15 to 59 — shrank 5%, or roughly 45 million people. When worker shortages began emerging over a decade ago, factories began moving to poorer inland provinces and then cheaper countries including Vietnam. In recent years some indicators suggest jobs are getting harder to fill, though the data might not be nationally representative.

Is China’s population shrinking?

Link: https://www.economist.com/china/2021/04/29/is-chinas-population-shrinking

Graphic:

Excerpt:

The Communist Party has long known that, partly as the result of its brutal birth-control policies, China’s population would soon peak and start to shrink. It has been startled, however, by how rapidly that moment has drawn near. Now, it looks as if it might have arrived.

….

There are also indications that China’s total fertility rate (the number of children a woman is expected to have in her lifetime) has dropped faster than previously thought. Chinese planners have assumed a rate of 1.8, but some Chinese scholars (and the World Bank) say it between 1.6 and 1.7. A working paper released in March by China’s central bank suggests the rate is no more than 1.5.

The origin of COVID: Did people or nature open Pandora’s box at Wuhan?

Link: https://thebulletin.org/2021/05/the-origin-of-covid-did-people-or-nature-open-pandoras-box-at-wuhan/

Excerpt:

A tale of two theories. After the pandemic first broke out in December 2019, Chinese authorities reported that many cases had occurred in the wet market — a place selling wild animals for meat — in Wuhan. This reminded experts of the SARS1 epidemic of 2002, in which a bat virus had spread first to civets, an animal sold in wet markets, and from civets to people. A similar bat virus caused a second epidemic, known as MERS, in 2012. This time the intermediary host animal was camels.

….

Contrary to the letter writers’ assertion, the idea that the virus might have escaped from a lab invoked accident, not conspiracy. It surely needed to be explored, not rejected out of hand. A defining mark of good scientists is that they go to great pains to distinguish between what they know and what they don’t know. By this criterion, the signatories of the Lancet letter were behaving as poor scientists: They were assuring the public of facts they could not know for sure were true.

….

One of the very few establishment scientists to have questioned the virologists’ absolute rejection of lab escape is Richard Ebright, who has long warned against the dangers of gain-of-function research. Another is David A. Relman of Stanford University. “Even though strong opinions abound, none of these scenarios can be confidently ruled in or ruled out with currently available facts,” he wrote. Kudos too to Robert Redfield, former director of the Centers for Disease Control and Prevention, who told CNN on March 26, 2021 that the “most likely” cause of the epidemic was “from a laboratory,” because he doubted that a bat virus could become an extreme human pathogen overnight, without taking time to evolve, as seemed to be the case with SARS2.
