Coronavirus Chronicles — The Dawn of Comprehension About Transmission

Confusion about school safety is affecting all American children, and anything that affects children is practically guaranteed to have more of an impact on those who are obese, or who deviate from average in some other way. Schools will not be safe until the obscure details of SARS-CoV-2 transmission are made clear, and though we seem to be getting closer, that goal is still not within reach.

For Scientific American, Christie Aschwanden gives several examples of swift and powerful spreading, and describes how one person can infect a frightening number of others without half trying. The trouble is, COVID-19 takes so long to develop into a recognizable illness, and many people never really look or feel sick, but meanwhile they can spread the virus like a house afire.

According to Lauren Ancel Meyers, executive director of UT Austin’s COVID-19 Modeling Consortium, the Centers for Disease Control estimated at this time that about 40% of coronavirus transmission happens before the person shows any symptoms — if indeed they ever do become symptomatic. Aschwanden writes:

Scientists have identified factors that catalyze such events, including large crowd sizes, close contact between people and confined spaces with poor ventilation.

A preliminary analysis of 110 COVID-19 cases in Japan found that the odds of transmitting the pathogen in a closed environment was more than 18 times greater than in an open-air space.

The largest clusters were found in indoor spaces such as nursing homes, churches, food-processing plants, schools, shopping areas, worker dormitories, prisons and ships.

Toward the end of June, thanks to diligent contact tracing, the Tulsa Department of Health was able to name the “Serious Seven” transmission events: weddings, funerals, faith-based activities, bars, gyms, house gatherings, and other small events. Around the same time, the Oklahoma City-County Health Department analyzed recent data and identified the “Serious 6” riskiest locations — jails/prisons, daycares, office settings, restaurants, manufacturing/warehouse (assembly line), and faith-based venues.

Robert Roy Britt, who writes extensively about the disease, noted a sudden increase in the number of infections among people younger than 50, including young adults and teens. It was starting to look as if the younger they were, the less likely these patients were to have debilitating or life-threatening symptoms. He suggested what might be behind this change:

More widespread testing is capturing more of the mild and asymptomatic cases, which tend to involve younger people. With severely limited testing capabilities in the early months of the pandemic, often only people with severe cases were tested.

Speaking of the young and healthy, a disturbing report came from the U.S. Army’s Special Warfare Center and School. Journalist Matthew Cox obtained information from military spokesperson Janice Burton, who explained that the prospective students are isolated for two weeks before starting any SWCS course.

At any given time, over 2,000 students are on the training base, and this time, one particular group turned up with 90 positive testers, including eight instructors and 82 out of the 100 students taking the curriculum. Consequently, “the course was terminated and all 110 soldiers are being quarantined for 14 days.”

Coronavirus Chronicles — Mysteries of Transmission

School may be better than home for most kids, and especially for obese kids. But will school ever again be what it was? In response to the pandemic, educational institutions might be poised to change extensively, and in ways that upset an astonishing number of groups for various reasons. School might become even worse for kids of every kind.

In pursuit of safe and viable schools, one of the major stumbling blocks is the mystery of transmission. In their quest to insert themselves into human populations, different disease organisms exhibit different patterns, and science does not seem anywhere close to having this one figured out.

For The New York Times, an incredibly talented team has made a map giving an animated account of exactly how the virus spread and how some outbreaks were traceable back to a single individual. In mid-February, when Washington announced the existence of 15 cases, there actually were an estimated 2,000 unrecognized cases. About half of them had come from outside the U.S. while others were connected to Seattle somehow. At first, only big cities were affected. But the creepy swarms of little red dots tell the story.

In June, belief was strong in the idea that the virus dies quickly in sunny, humid environments. In drier sunny weather, it was thought to live a little longer but not really be a serious threat. At the same time, Dr. Michael Osterholm and others had studied similar viruses that are unfazed by hot weather, so nothing was definite.

And then, there is the whole “superspreader” phenomenon. Currently it appears that as few as 10% of infected people could be responsible for about 80% of the transmissions. Why? University of California professor Jamie Lloyd-Smith says,

Some people with the virus may have a higher viral load, or produce more droplets when they breathe or speak, or be in a confined space with many people and bad ventilation when they’re at their most infectious point in their illness.

And now, here is a new cause for worry. It is quite possible that our beloved furry pets — including dogs, cats, monkeys, ferrets, and hamsters — might spread the coronavirus. They are already known to be susceptible to infection by it. In The Lancet Microbe, Professor Joanne Santini highlighted this as an area in need of prioritization, saying,

Virus transmission in animal populations could become irreversible if left unchecked, and may threaten the success of existing public health measures if people continue to catch the virus from an infected population of animals.

The suspects are not just pets, which is why Prof. Santini and other University College London scholars ask for “a mass surveillance program of all animals that live close to humans.” Creatures raised for commercial purposes, like rodents, pigs, and bats, are very capable of functioning as “reservoir species” where the virus can kick back and hang out, in between setting forth on murderous missions into the human stock.

After investigators in the Netherlands learned that two human mink farm workers caught COVID-19 from them, 10,000 animals had to be sacrificed, their fur unharvested, their lives wasted. How did the minks catch it? From feral cats. Fun fact: In America there are, by conservative estimate, at least eighty million (80,000,000) feral cats.

Coronavirus Chronicles — The Role of Air

Since the beginning of the pandemic, authoritative sources have stressed that SARS-CoV-2, the novel coronavirus, spreads through very close personal contact. For Vox, Journalist Brian Resnick explains the understanding that the World Health Organization (WHO) originally held:

The virus-laden droplets exhaled from a sick person’s mouth and nose, the thinking goes, are heavy, and fall to the ground before they can get much farther than 6 feet.

Then other clues began to show up, like a practice session where 52 healthy people and one suspected “superspreader” walked into a room, and 53 infected people walked out. These choir members may have shaken hands and even briefly hugged, but probably had no closer contact. Chances are, the problem lay not in brief personal interchanges, but in the cloud of aerosol droplets exuded by one person, that gradually infiltrated all the air in the enclosed space.

For some arcane traditional professional reason, many scientists have been willing to accept the “airborne” designation for only a strictly delineated class of illnesses. Finally, in mid-August, after receiving a letter of concern signed by 239 scientists and engineers, the WHO “changed its language to recognize that fact” and hopefully, to impress upon the world that the ventilation of indoor spaces is key.

Resnick’s article goes into much finer detail on how the droplet versus aerosol debate powered this controversy. The new understanding is explained in a basic way by MIT researcher Lydia Bourouiba, whom he quotes:

We’re always exhaling, in fact, a gas cloud that contains within it a continuum spectrum of droplet sizes. The cloud mixture, not the drop sizes, determines the initial range of the drops and their fate in indoor environments.

The people who produce these clouds do not even need to sing or shout. Normal conversation will do it. The behavior of any individual droplet is dependent on its contents (other than virus organisms), the environment’s temperature and humidity, and how fast the cloud travels.

Apparently, the outer layers of the cloud serve to coddle and protect a certain proportion of the aerosol droplets, enabling their ambitious journeys and influencing the length of time they remain viable. On the other hand,

Just because a virus travels far in a drop doesn’t mean it can infect people across great distances. Viruses can degrade quickly outside the body. Also, dose matters. Small exposures to the virus may not be enough to get a person sick.

Shockingly, “the virus can live in an aerosolized form for up to 16 hours.” But that does not necessarily mean it always does. The cause is, like so many other causes, multifactorial, and the risk is not an either/or proposition, but a spectrum.

One reason why people in the profession are picky about rigid categories regarding the definition and degree of aerosolization is that…

[…] there are very specific sets of guidelines in place to deal with extremely contagious airborne diseases in a hospital setting… “Airborne” means something very specific, very resource-intensive, and very scary for hospitals and the people who work in them. And Covid-19 doesn’t match that definition.

Transferring any of this knowledge from acute hospital and lab situations, to figuring out what to do about the schools to which children either do or not return, is making everybody crazy.

Coronavirus Chronicles — Obesity, Cause, Effect, and Distance

In June, Liji Thomas, M.D., pondered the question, “Obesity and COVID-19: Cause or effect?” She wrote,

Earlier studies have shown that diabetes figures could well rise in India, and childhood obesity in Italy, which will result in many more future deaths directly attributable to COVID-19, as well as indirectly caused by BMI-dependent cardiometabolic conditions.

Physical isolation and social distancing are of course very important in preventing infection by the virus. In the past few weeks, researchers have gained a lot of knowledge. It now appears that the virus can spread much more efficiently than was previously suspected. People should probably be isolating even more, and staying even farther apart.

The survival sweepstakes

Lockdown conditions mean that people do not travel far from home. No matter low their daily step count may have been before, when rules are made against movement, they take even fewer steps. They burn fewer calories and accumulate more weight. Under these conditions, one school of thought holds that figuring out a way to somehow get regular exercise is vital, on an equal footing with quarantine and physical distancing.

Chronic, underlying, pre-existing disease makes coronavirus worse. Of that there is no doubt. Can conscientious and purposeful exercise make it better? When a person who is in great shape catches COVID-19, does it stay for a shorter course than it otherwise would have? Will it be less damaging? Could it give up that nasty trick of lingering undetected, only to make a resurgence?

Dr. Thomas discusses a current observational study that asks how exercise-related factors shape the politics of lockdown:

[I]t indicates that the “burden of chronic diseases, even with a 3-month lockdown, may lead to a greater burden of excess deaths, highlighting avoidance of BMI gain and physical activity as public health priorities during the pandemic.

[R]ather than obesity, the target of health interventions should be the chronic diseases often associated with it, which are the determinants of the excess deaths.

Those are some very deep words. Maybe paying attention to them could help end the perceived stigma of obesity. A shift to deploring the poor condition of a heart, rather than the presence of an overcoat of fat all around it, might make a difference in how people act, in taking care of themselves and others.

What was that, about staying farther apart?

Using what has been called “a very clever measurement technique,” researchers studied the behavior of the floating virus. A paper that has not yet been peer-reviewed describes it:

A research team at the University of Florida succeeded in isolating live virus from aerosols collected at a distance of seven to 16 feet from patients hospitalized with Covid-19 — farther than the six feet recommended in social distancing guidelines.

The team used two samplers, one about seven feet from the patients and the other about 16 feet from them. The scientists were able to collect virus at both distances and then to show that the virus they had plucked from the air could infect cells in a lab dish.

If it turns out that viable virus can be cultured out of the air — this is big news. But the bigger news is, we might be kidding ourselves about this social distance thing. Some scientists go so far as to say that indoors, the supposed six-foot rule is invalid, and only leads us to feel safe when we are not.

Dr. Thomas’ article contains some amazing illustrations that visualize how, why, and how far the droplets travel.

Coronavirus Chronicles — The Many Factors in School Reopening

This is not the place for tracing the history of all the fallacious assumptions about COVID-19, but there certainly seem to be a lot of them. People used to think that its contagious droplets would not travel very far, or linger in the air for very long. Now, it appears that the droplets are more tiny than we can imagine, can travel farther than anyone had supposed, and hang around for a discouragingly long time.

At first, people believed, against all reason, that children possessed something close to immunity to the novel coronavirus. Then the evidence started to come in. Kids get it too, sometimes in sudden and dramatic form. Sometimes it appears mild, with a cruelly false recovery followed by “long haul” effects. There is a dawning awareness that when it comes to children’s safety, complacency is not our friend. The bottom line here is, whatever kids get, obese kids get it worse.

Okay! We’re concerned!

So, what do we do? For starters, suggests journalist Derek Thompson, we might think twice before being impressed by the words “deep cleaning” in relation to buildings and transport systems, which would include schools and buses.

In “Hygiene Theater is a Huge Waste of Time,” for The Atlantic, he explains. First, fomite transmission, or catching the virus from contact with surfaces, is not that big of a deal. While deep-cleaning the subways every night sounds great, it does more harm to the citizens than good. The evidence for surface transmission is so paltry as to be almost absent. (But we’re talking about COVID-19 here. There are still plenty of other things to catch, and people should still wash their hands thoroughly and often, just on general principles.)

Hospitals need regular deep-cleaning; in schools it probably does not help in this particular case, and is very likely to pull resources and energy away from other precautions that might make more sense. Like over-reliance on taking people’s temperatures, obsessive cleaning is perceived by some to be less of a preventative measure and more of an empty ritual.

The author sought information from microbiology professor Emanuel Goldman of Rutgers New Jersey Medical School, who takes into account not only financial reality but the “prevention fatigue” factor that enervates people:

They’re exhausted by all the information we’re throwing at them. We have to communicate priorities clearly; otherwise, they’ll be overloaded.

At a time when returning to school will require herculean efforts from teachers and extraordinary ingenuity from administrators to keep kids safely distanced, setting aside entire days to clean surfaces would be a pitiful waste of time and scarce local tax revenue.

My point is not to relax, but rather to focus on what matters and what works. Masks, social distancing, and moving activities outdoors. That’s it. That’s how we protect ourselves. That’s how we beat this thing.

Lest we forget, schools have more than one item on their agenda. In many places, school is where kids get not only high-standard nutrition, but any nutrition at all.

Economically comfortable Americans have no real grasp of what it means to be food-insecure, and others have no understanding of how much obesity is caused by kids filling up on cheap and over-processed pretend-food. Frederick M. Hess wrote,

America’s schools are a primary source of food for millions of students in the free- and reduced-price lunch program. As the massive national database compiled by my American Enterprise Institute colleague Nat Malkus shows, within two weeks of schools’ being closed, more than 80 percent of them were providing some type of meal service, and 30 percent were delivering meals to kids.

Coronavirus Chronicles — School and Its Perils

Somehow, word got around that COVID-19 was unlikely to either infect, or be transmitted by, children. Researchers desperately scrambled to find reliable and sufficiently large data sets to verify the relative safety of kids. But then, the results started to be published, and meanwhile, individual reports trickled into the public consciousness.

At the end of July, for instance, the world learned that a sleep-away camp in the American state of Georgia had been the site of a serious outbreak. The proprietors had read the Centers for Disease Control recommendations and half-heartedly gone through the motions on some of them.

Cloth masks were required for staff members. Camp attendees were cohorted by cabin and engaged in a variety of indoor and outdoor activities, including daily vigorous singing and cheering. Measures not implemented were cloth masks for campers and opening windows and doors for increased ventilation in buildings.

Masks for the grownups, but not for the kids, is the procedure in many schools, or will be when they open. Another thing about schools is, the ventilation suggestion will be very hard to follow in many parts of the country where temperatures are extreme. Picture a classroom where the students are bundled in their winter coats, hats, and gloves (and possibly even wearing face covers) for the sake of healthful fresh air circulation. Or maybe the windows don’t open. A modern HVAC system, if a school is lucky enough to have one, is not designed to be interfered with.

Anyway, in order to be accepted by the woodsy center intended to provide for fun and cultivate growth, both campers and staff had been required to prove that they tested negative within 12 days of the start of the session. In a world that offers so many opportunities to catch the disease that is an extraordinarily lenient window.

The report details that 231 campers under the age of 18 tested positive, nearly half of the 509 total children at the camp. An additional 29 people over the age of 18, out of 89 at the camp, tested positive.

At the beginning of August, Sarah Bowden of Georgia wrote about another establishment:

The day camp my son went to was limited to 60 kids per day, split into 2 year age groups with 6 kids per counselor/room, did temp checks and hand sanitizing before kids even got out of their car, and required staff and campers to wear masks. He still got #COVID19.

An article written by Rachel Schraer for BBC.com elicited 2,541 responses before comments were closed, so it obviously touched a nerve. One topic is the news from the United Kingdom’s Office for National Statistics, about a relatively small study. The researchers admit that it is “hard to make any strong conclusions,” about who is at the most risk of catching COVID-19, but here are a few of the observed patterns:

Those in people-facing health or social care roles, and working outside their homes in general… People from ethnic minority backgrounds were more likely to have a positive antibody test, suggesting a past infection… There was also some evidence that people living in larger households were more likely to test positive than those in smaller households.

This survey also added to the growing suspicion that a very large proportion of positive testers never experience any symptoms. Elevated temperature is a symptom, and apparently a lot of positive testers run hot only intermittently, or never. Investors who rushed to buy stock in the booming no-touch digital thermometer business may want to reconsider. This device is useful as a tool, but really should not be asked to serve as the tool.

Coronavirus Chronicles — What If Summer Slide Never Ends?

As we know, summer vacation has mixed effects on school-age children. The physical problem is counterintuitive, but real. Anyone who holds a mental picture of kids getting lots of exercise and slimming down over the summer will likely turn out to have been comically optimistic.

Sure, exceptionally motivated kids can use the long break to recreate their physiques, but not that many go for it, and this year has really put a lid on opportunities to use any facilities, whether publicly or commercially owned. In that respect, the early start made Summer 2020 worse than most. Not discouraged yet? There is, as Childhood Obesity News discussed, more, namely a comparable backward creep in the book-learning department.

School is only part of the pandemic’s cascade of consequences, but it is a very big part for young people and their parents. Now, add the awful affinity that COVID-19 and obesity share. They aid and abet one another like long-time cellmates who spent years plotting the perfect bank heist, and now are free to carry it out. Everything about the present crisis is worse for overweight and obese kids, and indeed for persons of any age with food-related issues. Or medical problems. Or mental health vulnerabilities.

Lately, every day brings some new horrifying headline. Yesterday, for instance: “More than 97,000 children tested positive for Covid-19 in the last two weeks of July, report says,” and they’re talking about the United States of America. Also, every day more schools are reopening.

Snitches get stitches

At a May meeting of Georgia’s Paulding County School District, board chair Jeff Fuller told listeners that COVID-19 would not affect students, and deprecated the Centers for Disease Control guidelines as “hype” and “complete crap.” Not surprisingly, the iconic story that currently captures media attention is playing out at North Paulding High School (NPHS).

On the first day back, a female student took a picture of the claustrophobically crowded hallway, where masks were worn by 10% or less of the students, and published that photo on social media. She was suspended from school, and other aspiring whistleblowers were warned that such behavior would not be tolerated. The administration announced over the PA system that any further exposure would be answered with “consequences.” Blabbermouth students were threatened with suspension, and teachers with bad marks in their employee files.

A teacher anonymously posted confirmation that other schools in the district looked the same, did no screening, and made not the feeblest effort to stagger the students’ arrival times. A school nurse resigned. An administrator proclaimed masking to be a personal choice that the district had no way of influencing. Online commentators snorted in derision, noting that schools seem quite able to police skirt length, t-shirt slogans and artwork, and even the very personal matter of student hairstyles.

Seven NPHS students and two staff members tested positive for COVID-19, and last week ended with the determination to switch to remote learning for Monday and Tuesday, August 10 and 11. (Relative to our publication date, that’s yesterday and today.) If all goes according to schedule, the next step will be announced this evening.

The good news is, student’s suspension was lifted and will not appear on her record. The bad news is, the prospects for resumption of full-time in-person school, in Georgia or most of the U.S., do not look promising.

Coronavirus Chronicles — Will Summer Slide Be a Permanent Condition?

Dr. Samareh Hill is Medical Director of WakeMed, a program whose function is to manage excess weight and associated health conditions in children and teens. Dr. Hill says that the quarantine has caused kids to gain from 5 to 30 pounds. Of course, part of that is a normal, expected phenomenon that some call the summer slide.

Childhood Obesity News has quoted several experts who are dismayed to verify that children do not work off their extra pounds during school’s long break, but actually add weight. This year is likely to be worse, as described by KentuckyToday.com:

The loss of opportunities for physical activity from school closures, especially when coupled with potentially diminished nutrition, can be particularly harmful to children. Current models estimate that childhood obesity rate may increase by 2.4 percent if school closures continue to December 2020.

A comparable “summer slide” takes place in the intellectual realm:

According to the Northwest Evaluation Association, in the summer following third grade, students lose nearly 20 percent of their school-year gains in reading and 27 percent of their school-year gains in math. By the summer after seventh grade, students lose on average 39 percent of their school-year gains in reading and 50 percent of their school-year gains in math.

Because of all the potential developmental effects on children, extended school closure is being massively resisted. There are other issues too.

In New York City, journalist Keith Gessen interviewed the president of the local branch of the International Union of Operating Engineers. Also known as building custodians, they are in charge of everything having to do with a school’s physical plant. Robert Troeller explains how a lot of words have been said — not by the workers — about what these union members will do. The politicians promise “deep cleaning,” a term that had already possessed a specific meaning in the school maintenance lexicon.

Before COVID, Troeller says, deep cleaning referred to what happened during the summer, when entire buildings were scrubbed and painted and waxed from wall to wall. “That’s certainly not happening overnight,” he says. “I think what they’re talking about is that each horizontal surface will be wiped down and cleaned and sanitized.”

Payment for all these extra labor hours and supplies is to be eked out of a budget no larger than last years’. Troeller also adds that most of the city’s schools are so old they do not have HVAC systems. Considering that one of the principles of infection avoidance is to keep fresh air circulating, this is ominous. The fresh air recommendation does not bode well for the students’ ability to keep warm in class in New York’s frigid winter.

New York’s problems also point out why, in these matters, it is so difficult to rule from the top. The federal government has no idea how to make useful laws about school closure that work in every corner of America. These things need to be figured out by honest, informed, and responsible local authorities.

Gessen also sought information from Dimitri Christakis, editor-in-chief of the journal JAMA Pediatrics, who wants schools open, and expresses a reluctance to leave the decision in the hands of local authorities, scientists, experienced plague wranglers, or anyone else other than politicians.

The entire debate, he says, is being dominated by infectious-disease experts. “If you ask them, ‘Can schools play an important role in the transmission of the virus?,’ the answer is, ‘Yes, they could!’ But they’re not thinking about the risks of not opening schools. Our children have already paid a heavy price, and they’re going to pay a heavier price if we keep them out.”

Coronavirus Chronicles — Factorial Multiplicity

The term “multifactorial” has been used before, in reference to the bewildering number of discoveries that have been made about obesity. Childhood Obesity News has used it often. An influential factor might exert only a tiny effect on the body, and contribute only a fractional number to the obesity statistics.

But so many things are accused of being responsible, in mysterious ways, for encouraging the body to create and hold onto fat cells. The “obesity villains” file holds so very many suspects, at least a portion of them must be guilty. If a grooming product contains a chemical that somehow causes an eight-ounce weight gain over a year, so what? It’s no big deal, right? But what if it turns out to be true that eating from plastic dishes makes people fat? Now, the person is carrying around an extra pound.

In the obesity field, hundreds of minor-league obesity villains have been proposed, and some have been proven. As a thought experiment, suppose that a person’s environment only holds 20 of those mini-factors, The average amount of weight each one puts on a person is eight ounces. Multiplied by 20, that’s 10 pounds a year of weight gain that is totally unconnected with nutrition or even bare sustenance.

Whether in an individual or a population, the annoying tiny effects tend to pile on until collectively they pose a serious threat to health. There is also the synergy aspect to contend with. Two seemingly minor-league obesity villains can team up and do some real damage.

The coronavirus connection

Information about the novel coronavirus comes at us thick and fast, and a lot of it has to do with factors. Age is a factor, but in different countries, things go on that might make age a much less meaningful factor — or even more significant than previously believed. Some precepts are true in one place but not a hundred miles down the road, or not among people with different colored skin. How the virus acts and how humans react turns out to be multifactorial, and people should probably know more about that before reopening schools.

Everyone is carrying around a vast number of assumptions about COVID-19 that may not be accurate or even up to date. Zeroing in on children, Dana G. Smith examines five leading theories about them and the virus. Hopefully this brief summary will not satisfy, but encourage the reader to go read the whole article.

First, the idea has become entrenched that contagion is stymied because children have fewer ACE2 receptors, which are the virus’s favorite place to latch on. While it is tempting to believe that this makes children less efficient at shedding and spreading, this is probably not true in all cases. Smith also writes,

Another possibility is that there is something different in the immune systems of young children that scientists haven’t accounted for yet. As kids age and their bodies go through puberty and look more like adults, they start to respond to the virus more like adults, too. For instance, in countries that have reopened schools, several outbreaks have occurred in high schools, but there have been relatively few cases in elementary schools.

Then, there is a fancy theory that kids’ immune systems are tough enough to habitually deal with the common cold, which is another kind of coronavirus, so COVID-19 is no problem for them. Another suggestion is that children are pretty much socially isolated by parental fiat — but in the shanty towns of Third World cities, this could not be nearly as possible as in the New Jersey suburbs.

In places where only children who seem sick are tested, a lot of positives will be found. In all the excitement, nobody has been particularly eager to test a bunch of asymptomatic children. But apparently there have been places where large numbers of asymptomatic children were tested, just out of curiosity, and shockingly large numbers of them showed positive for COVID-19.

Coronavirus Chronicles — Physical, In-Person, On-Site School

As we have seen, obesity has an intensifying effect. Any problem that children and teenagers ever run into is magnified by also being uncomfortably or dangerously overweight. It’s as if fat cells and COVID-19 have entered into some unholy alliance for mutual aid. Whether the virus succeeds in making everybody stay home, or whether in-person school is attempted, either way, the downsides will hit the obese young people worse.

Sarah Jones wrote for New York magazine:

Kids need real classrooms, trained teachers, and socialization they don’t get at home; the absence of each will harm low-income students the most… But low-income families face daunting obstacles. The pandemic deepens their disadvantages, and eats up whatever equity public schools achieve for their children.

Teachers are afraid these children will fall farther and farther behind.

And, what a coincidence. Disadvantaged, low-income students also have more of a tendency to develop obesity, and so do minority children, and there is often a lot of overlap among these groups.

Caution: Jones’ article about the consequences of various school-related choices could keep a person awake at night.

What is needed?

Kids need trained teachers, sure, and they also need empathetic teachers. A really good teacher figures out how to encourage children for their individual strengths and interests. This is so, so hard to do over a communal video feed, for more than one reason.

Socialization involves more than just learning how to say “please” and “thank you.” For a kid who is different in a non-approved way, like being too heavy, we’re talking about the development of skills. Some kids figure out how to deflect negativity with humor. Some learn how to play a musical instrument, or fix people’s computers, to earn forgiveness for being fat.

Author Shayla R. Griffin, Ph.D., discusses Dr. Fauci’s recommendations to make schools safe:

Low Covid-19 rates in the community;
Regular testing of all school personnel and students;
Robust contact tracing;
Mandatory mask usage of all students, starting from the moment they board the school bus; and
PPE for all educators, including masks, goggles or face shields, gloves, and “coverall” clothing that is easy to take off once the school day is over.

Not to be negative, but trying to convince a class of young children to wear their masks properly all day seems like a fool’s errand. That challenge alone will defeat many teachers. Where will the masks come from? Somebody needs to pay for them, and it probably will not be the families, not when many families can’t even afford to feed their kids breakfast. When even doctors, nurses, and other health-care personnel can’t get enough masks, how is this going to work out for school children?

And what about the teachers? Who will pay for their personal protective equipment, and for their hospital bills if they catch the virus? Fortunately, that question has been answered. Schools are having today’s equivalent of the old time school Bake Sale. Griffin says:

Many districts have already been doing public fundraisers for PPE donations, which raises concerns about whether or not we will actually have enough masks, goggles, gloves, and sanitizer for all students and staff.

But speaking of money, a stern reminder comes from Noah Rothman, who not only emphasizes that financially solid citizens are upset, but that America as a country seems to have given up on any notion that school opportunities should be equal:

[T]he indefinite postponement of in-person education is an abrogation of the social contract. Those who sought out their districts and pay property taxes commensurate with the services they pursued are being told they are out of luck. And they’re not entitled to a refund.
