For “herd immunity” to be achieved, the entire herd must be included, and that’s just one of the considerations we’re currently grappling with.

One of the big problems with SARS-CoV-2 is that so many aspects of the organism and its behavior remain shrouded in mystery.

The virus makes no exceptions for minors. They can catch it, they can spread it, and they can die from it.

COVID-19 may predispose people to baldness, just as it makes them more vulnerable to developing obesity.

The year 2000 was not a complete disaster as at least some useful research came out, on how the young are susceptible to COVID-19.

For months, a citadel of wishful thinking that children don’t easily contract and spread the virus had been constructed. Now it began to crumble.

Ordinary people who record their mukbang experiences on social media provide useful anecdotal evidence — the fertile ground from which evidence is born.

There is the disagreement about whether some calories are good while others are bad. Also, there is the energy balance controversy.

A calorie is not just an energy unit, and all calories are not created equal. The evidence continues to pile up.

One theory holds that 3,500 calories equal one pound of body weight, so, to lose a pound a week, a person has to cut their intake by 500 calories per day.

The fetishization of calories by generations of weight-conscious eaters seems to have brought disaster. Even with the help of fancy technology, people just don’t seem able to keep energy consumption on a leash. There is a happy medium between compulsiv …

We continue the discussion on how people of color pay a disproportionate price for catching coronavirus, and how this is especially true if they are obese.

Obesity, poverty, and minority group membership are factors that work in concert to provide the “perfect storm” situation for COVID-19.

Both obesity and COVID-19 see it as their mission to devastate the world, and both believe they can destroy more efficiently as a team.

Any numbers the Centers for Disease Control can lay hands on, that agency will crunch, mash and hash to a fare-thee-well. As always, the fate of newborns is of particular interest. There is some indication that a prospective mother who tests positive f …

Coronavirus is still with us, and this blog has been looking at transmission and how to stop it, especially relative to schooling.

It’s becoming increasingly apparent that infected children can be shockingly contagious, even when they show no symptoms of illness.

The CDC is not tracking school-based COVID-19 cases. Could there be a more perfect recipe for disaster?

Massive protests were thought to be a prime enabler of community transmission of the virus, except it wasn’t the case.

As it turns out, the protests may not have caused any dramatic increase in the spread of COVID-19. The “superspreader” events tend to be indoors.

Immunity? Nobody knows. Human behavior? Nobody knows. It’s the engine that drives history. Most mysteries boil down to human behavior, and people are crazy.

In pursuit of safe and viable schools, one of the major stumbling blocks is the mystery of transmission. And now there’s a new cause for worry, related to pets.

There are reasons why scientists are picky about rigid categories regarding the definition and degree of aerosolization as applied to the coronavirus.

If it turns out that viable virus can be cultured out of the air — this is big news. Even bigger news is, we might be kidding ourselves about social distancing.

What that could happen when schools reopen is predictable, because they are happening now in some childcare facilities across the U.S., including Texas.

Body temperature is a maddeningly unreliable indicator of disease, and basing the pass/fail system on it sounds a bit shaky.

Coronavirus neither recognizes nor respects arbitrary lines drawn on maps, so going at this problem state-by-state is a losers’ game.

Today’s post picks up on the discussion of back-to-school protocols suggested in late June by the American Academy of Pediatrics.

In the current state of chaos, it is more likely that the medical profession as a whole has only a sketchy picture of what is going on with young people.

It’s been half a year, and nobody has a lock on how coronavirus spreads. It’s estimated that close to half of the people who have it might be asymptomatic.
