Four Covid Links

Tracking coronavirus infections in the US, from The National Geographic

What the current spike in Covid-19 cases could say about the coronavirus’ future, from StatNews

As the Omicron wave subsided in the United States earlier this year, many experts anticipated a sort of reprieve. We certainly weren’t done with Covid, but perhaps we would get a well-deserved rest.

That break seems to be over.

An increase in infections that began in places including the Northeast and Puerto Rico is now being seen in other parts of the country. Cases will rise and fall going forward, but more worryingly, hospitalizations have started to increase as well — up 20% over two weeks. The decline in deaths has bottomed out at some 350 a day....

The ‘five pandemics’ driving 1 million U.S. Covid deaths, also from StatNews

...Analysis of the data will continue for years, but it is clear that, when it comes to deadliness, there were five different pandemics — depending on when and where you lived, and who you were.

Earlier vs. later
Older vs. younger (but there’s fine print)
Unvaccinated vs. vaccinated
Rural vs. urban
Poorer vs. wealthier

America Is Starting to See What COVID Immunity Really Looks Like, from The Atlantic

With time and effort, we can build enough protection to blunt surges—but herd immunity remains out of reach.

...Roughly 60 percent of people in the U.S. have caught SARS-CoV-2, according to the latest CDC estimates, which go through February of this year.

And that’s very possibly a serious underestimate. The Institute for Health Metrics and Evaluation, a global health-research center at the University of Washington, puts the tally higher, at 76 percent, as of the beginning of April. And Virginia Pitzer, an epidemiologist at Yale’s School of Public Health, who’s been modeling infections and vaccinations among Americans, told me the true number might even exceed 80 percent.

No matter how you calculate it, though, the proportion of Americans who have been infected dwarfs the fraction who are up-to-date on their vaccines.

Covid news

The pandemic led to nearly 15 million excess deaths worldwide in 2020 and 2021, the World Health Organization said in a new estimate published this week. Some of those deaths were caused by the virus, but many occurred as hospitals were overwhelmed with covid-19 patients and people did not receive care for other conditions. Nearly two-thirds of those deaths were concentrated in just 10 countries, including the United States.

The Biden administration on Friday warned that a fall surge could infect up to 100 million people, my colleagues Yasmeen Abutaleb and Joel Achenbach reported. New omicron subvariants that appear to be very good at evading immunity could drive a sharp increase in cases in coming months. And a possible summer surge in the South could use up the nation’s supply of antivirals and tests just before the fall arrives.

Over 50% of U.S. Population Has Contracted COVID-19, CDC Says, from MedPage Today

— But prior infection does not guarantee protection against reinfection, officials caution


Half of the U.S. population has been infected with COVID-19, including 75% of children and adolescents, CDC officials announced on Tuesday.

From December 2021 to February 2022, during the Omicron wave in the U.S., overall seroprevalence increased from 33.5% to 57.7%, reported Kristie Clarke, MD, of the CDC's COVID-19 Emergency Response Team, and colleagues in an early edition of the Morbidity and Mortality Weekly Report.

Over this same time period, seroprevalence increased from 45.6% to 74.2% among adolescents ages 12 to 17, and from 44.2% to 75.2% among children ages 11 and younger.

"We definitely expected to see an increase. We didn't expect it to increase quite this much, but we follow the data," said Clarke at a media briefing.

COVID Was Third Leading Cause of U.S. Deaths in 2021, Says CDC, from MedPage Today

— But agency sees racial disparities shrink versus 2020

While COVID-19 in 2021 was again the third leading cause of death in the U.S., racial and ethnic disparities narrowed from the year before, provisional CDC data indicated.

Overall, 65.2% of the COVID-19 deaths in 2021 were among white individuals, 16.5% were among Hispanic individuals, and 13.3% were among Black individuals. In 2020 these proportions were 59.6%, 18.6%, and 16.1%, respectively, reported Benedict Truman, MD, of the CDC and COVID-19 Emergency Response Team, and colleagues in the Morbidity and Mortality Weekly Report (MMWR).

Nurse in COVID Vax Death Conspiracy Is Alive; How COVID Disinformation Kills, also from MedPage Today

Nurse in COVID Vax Death Conspiracy Is Alive

Tiffany Dover, RN, fainted on live TV after being among the earliest cohort of healthcare workers to get the first COVID-19 vaccinations in December 2020. She recovered, and was back in front of the cameras in 20 minutes, but rumors about her death had already started to swirl.

How COVID Disinformation Kills

A family from Long Island told NPR that COVID-19 conspiracy theories are what really killed their mother.

NPR traced the story of 75-year-old Stephanie, who had refused to get vaccinated against COVID-19 because she believed the shots contained microchips. Stephanie died of COVID-19 in December 2021 after also refusing remdesivir and monoclonal antibodies when she was hospitalized.

The future of the pandemic is looking clearer as we learn more about infection, from NPR

A very good article on the topic

Why Do Some People Escape Infection That Sickens Others?, from Medscape

It is a great mystery of infectious disease: Why are some people seemingly unaffected by illness that harms others? During the COVID-19 pandemic, we've seen this play out time and time again when whole families get sick except for one or two fortunate family members. And at so-called superspreader events that infect many, a lucky few typically walk away with their health intact. Did the virus never enter their bodies? Or do some people have natural resistance to pathogens they've never been exposed to before encoded in their genes?

Resistance to infectious disease is much more than a scientific curiosity and studying how it works can be a path to curb future outbreaks.

Can Dietary Habits Impact COVID-19 Outcomes?

"...And this was one of two, I thought, particularly compelling studies that just came out a few weeks ago. And as you said, they looked at almost 3,000 frontline health care workers who get exposed to COVID every day. And they found that those that were eating a healthy plant-based diet were 73% less likely to get moderate to severe COVID. Those following a pescatarian diet, a healthy plant-based diet with some fish, were 59% less likely.

And equally amazing, those following a high animal protein, high fat-- Atkins, paleo, Keto-type diets-- were 400% more likely to get moderate to severe COVID. So we already know that a healthy plant-based diet has so many beneficial effects beyond COVID. But I think this is just the latest example of things that we can do ourselves to help enhance our immunity...."

Scientists name newly discovered flatworm after covid-19, from The Washington Post

There’s plenty of creepy, crawly stuff in the soil, and organisms such as worms, snails and slugs are essential to the planet’s health.

But flatworms, a subset of creepy creatures that feed on those soil dwellers and gobble up biodiversity in the process, are a threat to the world’s dirt. Now, scientists have identified two new species of the alien-appearing animals — and named one after covid-19.

It’s called Humbertium covidum, and although the specimens studied were found in France and Italy, it may also be in China, Japan and Russia....

The city’s schools have been shuttered for more than 600 days, in what amounts to one of the world’s longest covid-induced school closures...


Why Deaths of Despair Are Increasing in the US and Not Other Industrial Nations—Insights From Neuroscience and Anthropology

The US National Academy of Sciences reports rising mortality for US adults, most steeply for White adults with a secondary education or less. The rise is largely attributable to deaths of despair (suicide and poisoning by alcohol and drugs) with strong contributions from the cardiovascular effects of rising obesity....

...Deaths of despair combined with metabolic and cardiac deaths exceed by 4-fold the next important cause of death, cancer. Moreover, when primary liver cancers caused by alcoholism (50%) and lung cancers caused by smoking (90%) are included, the total number of deaths exceeds the remaining cancers by nearly 5-fold. This annual mortality rate far exceeds that caused by the COVID-19 pandemic, and unlike the COVID-19 pandemic, it shows no signs of abating...

Jeremiah Stamler, Pioneer of Preventive Cardiology, Dies at 102

On the occasion of his 100th birthday, The Washington Post wrote of the trailblazing cardiologist and scientist Jeremiah Stamler, MD: "You may not know him, but he may have saved your life."

Hyperbole, it was not.

Over a career spanning more than 70 years, Stamler transformed medicine and the public's understanding of diet and lifestyle in cardiovascular health and helped introduce the concept of readily measured 'risk factors' such as cholesterol, hypertension, smoking, and diabetes.

'Post-Truth Era' Complicates COVID-19 Response, Trust in Science

...The new study ― The Rise and Fall of Rationality in Language, published in the Proceedings of the National Academy of Sciences ― found that facts have become less important in public discourse.

As a result, unsupported beliefs have taken precedent over readily identifiable truths in discussions of health, science, and politics. The upshot: "Feelings trump facts" in social media, news reports, books, and other sources of information.

And here's the kicker: The trend did not begin with the rise of former President Donald Trump, the COVID-19 pandemic, or the advent of social media; in fact, it has been growing for much longer than you might think....

Vaccination, Religion, and Science: An Astonishing 300-Year-Old Story

— It's time for a history lesson in the roots of vaccine advocacy and resistance

The debate about COVID-19 vaccinations rages with fury -- to an extent that has gone beyond the realm of medicine or rational thought. Some readers might believe that those who are strongly grounded in science are inevitably vaccine advocates, whereas those who are vaccine resistant are willfully ignorant of the facts or live life as religious fanatics.

Such assumptions are horribly unhelpful in the current era. But a short history lesson demonstrates that these preconceptions are historically inaccurate, especially if we explore the origins of vaccination in the U.S. Americans have a strong tradition of both vaccine advocacy and resistance, and the inceptions of these movements are astonishing. We can gain important insights by going back 300 years -- to the Boston Smallpox Epidemic of 1721....

Inside this Maryland ICU, a depleted staff struggles to keep going

...Like hospitals across the country, Luminis Health Doctors Community Hospital is facing a two-pronged crisis in this surge, with thin staffing and more covid-19 patients than ever before. Employees who remain have no choice but to shoulder bigger burdens. Among the heaviest, they say, is the emotional weight of so much preventable death.

About 70 percent of patients admitted to the hospital are unvaccinated, as are more than 90 percent of those who die there.
...
“Everyone in the hospital dealt with lack of PPE, a lack of testing, health-care narratives rooted in political nonsense … on top of all the death,” said Kanak Patel, the ICU [medical director].

“You put any workforce through that,” he added, “and it’s not going to be whole. And we’re far from whole right now.”...


U.S. coronavirus hospitalizations slow, with the Northeast showing a steep decline

...But in some corners of the nation, hospitals continue to reel from waves of omicron infections, creating chaos as droves of patients seek care during an already busy season, and front-line workers head to the sidelines in greater numbers than at any point in the pandemic. Some hospitals are finding valuable medical supplies harder to come by, even as the days of widespread shortages of personal protective equipment have passed.

On Wednesday, U.S. hospitals reported treating about 150,000 coronavirus patients, down from a record 160,000 last week. Per capita admissions are starting to decline sharply in the Northeast, to about 50 per 100,000 residents, on par with the South, where hospitalizations are leveling off. Hospitalizations are also falling in the Midwest but rising in the West....

Where Are the Public Health Experts When We Need Them Most?

...We may or may not like the answers we get, but we will all get terribly distressed if the answers change from month to month -- or from week to week. We get particularly confused when different leaders give different answers to the same questions during a 3-day period.

Some leaders will say they are following the "science." But as a scientist, I do not understand what this is supposed to mean. Throughout most of this pandemic, we did not have enough reliable data to make an informed decision. In the absence of reliable data, how does one "follow the science?" Claiming we are "following the science" in the absence of data simply gives science a bad name....

Investigator Planned to Make Vast Profit From Autism/MMR Vaccine Scare, BMJ Says

Deborah Brauser

January 13, 2011 — Andrew Wakefield, the lead author on the 1998 study that reported a link between the measles-mumps-rubella (MMR) vaccine and a new condition of regressive autism and bowel disease called autistic enterocolitis (AE), was planning to market a prestudy diagnostic testing kit with expected yearly sales of 28 million pounds (43 million US dollars), a new paper published online January 11 in the BMJ reports.

In the second of a series of 3 investigative articles examining the MMR vaccine scare, UK journalist Brian Deer reports that Mr. Wakefield planned several businesses to develop not only the new test but also immunotherapeutics and a "safer single measles shot" — which he held a patent for. Mr. Deer writes that these would only be successful if public confidence in the MMR vaccine was damaged.

Autism and MMR Vaccine Study an 'Elaborate Fraud,' Charges BMJ

Deborah Brauser

January 6, 2011 — BMJ is publishing a series of 3 articles and editorials charging that the study published in The Lancet in 1998 by Andrew Wakefield and colleagues linking the childhood measles-mumps-rubella (MMR) vaccine to a "new syndrome" of regressive autism and bowel disease was not just bad science but "an elaborate fraud."

According to the first article published in BMJ today by London-based investigative reporter Brian Deer, the study's investigators altered and falsified medical records and facts, misrepresented information to families, and treated the 12 children involved unethically.

In addition, Mr. Wakefield accepted consultancy fees from lawyers who were building a lawsuit against vaccine manufacturers, and many of the study participants were referred by an antivaccine organization.
