England’s world-beating Covid test and trace system has people beating their heads against the wall. Anyone can mistake a wall for the world. It’s natural enough. Even in pandemic hot spots, symptomatic people are being turned away. The government’s labs had a backlog of 185,000 tests that were sent abroad over the weekend. But if test samples sit around too long, they’re useless. So, um, yeah. I’m not sure how that’s going to work. But let’s not be silly and hold out for competence.

English schools are warning that they’ll grind to a halt if students and staff can’t get tested, because people who might test negative will have to isolate.

Wales says it’s going to process its own tests. Scotland accused England of trying to limit its access to tests. Northern Ireland doesn’t seem to be taking part in the conversation, and nobody ever listens to Cornwall.

Meanwhile, Doug Jaquier sent me a bit of wisdom from a Facebook site called Puns, One Liners & Clever Wordplay: 

“Due to the success of Covid testing the Government has taken over pregnancy testing too. The waiting list is currently 10 months.”

The capitalization is not mine. Neither, sadly, is the inventive mind that thought of that. If they’d waited another lifetime, I would’ve come up with it. I just know I would’ve.

China has announced that it may have a vaccine ready for use by the public in November or December. It’s currently in phase 3 trials–the ones where they test it on a large number of people to see if it’s both safe and effective.

Britain’s Oxford vaccine phase 3 trials were interrupted when one of the test subjects got sick. They’ve resumed now. Presumably her illness was unrelated. Not that anyone’s actually said that. Confidentiality and discretion absolutely ruin a good bit of gossip.

An advisor to the British government said that details of the new rules limiting how many people can gather in what circumstances are irrational–you can get a larger group of people together for a sports event but a family of five can’t have two grandparents visit them at home. 

“It is on the other hand very simple,” he said.

And it is simple until you try to sort through the who, what, when, where, and how.

In case you were worried, you can gather in groups of up to thirty to shoot grouse. So don’t feel too bad about the grandparents. At least no one (that we know of) is hunting them.

A lot of Britain’s recent Covid cases are among younger people, so let’s talk about the people who it’s hitting like a sledgehammer. The reason I want to focus on them is that we have the illusion that Covid’s only a danger to people over sixty. Or seventy. Or eighty. Younger people are immune. 

Okay, most of us have that illusion. You probably know better, but the rest of us can be pretty dumb sometimes.

At Mount Sinai Health System, in New York, doctors treated five Covid stroke patients in two weeks, all under fifty. Normally they’d see one every three weeks. Four of them were relatively healthy beforehand. Two were in their thirties and had no risk factors. 

That’s a lot of numbers in one paragraph. Five in two weeks instead of one every three. Hold onto that. It’s not a huge number, but it reminds us that the danger to younger people is real. If you have to draw a card out of the Covid deck, you have no way to know what card it’ll be. 

Dr. Adam Dmytriw, a University of Toronto radiologist, says, “We’re seeing a startling number of young people who had a minor cough, or no recollection of viral symptoms at all . . . and they have a sudden stroke.” 

How many is a startling number? Enough to startle a doctor. That’s the best I can do, because the article didn’t say. Some of them had underlying medical conditions, but none had risks that should have increased their chance of having a stroke. For some, the stroke was the first sign that they had the coronavirus because they had the mild cases we all expect them to have.

In the U.S., the number of hospitalizations among 18- to 29-year-olds quadrupled in just a couple months. From the week ending April 18 to the one ending June 27, it went from just under 9 for every 100,000 to roughly 35 per 100,000. It’s not a huge number, but it’s a big jump for a short stretch of time.

One study, again of Americans, says a third of all younger people have at least one risk factor for severe Covid. 

Other younger people end up with some version of post-Covid syndrome, which can include exhaustion, chest pains, migraines, breathlessness, dizziness. About 600,000 people (I think that’s in Britain, and it seems to include all ages, but don’t take my word for that) have some version of post-Covid syndrome as measured by the app Covid Tracker. Around 12% of them have had it for more than a month and one in two hundred for more than 90 days.

Something close to 100% of British publications (at least the ones I read) don’t bother to translate their statistics into comparable categories. I think that would be .5%, but I’m not going to crawl too far out on that limb.

The initial belief that Covid risk rises with age still seems to hold true, but even so the evidence is increasing that younger people aren’t immune. A retrospective Chinese study of Covid in children counts 2,143 cases. More than 90% of them were mild or moderate, but 6% of pediatric cases were severe and even critical, compared to 19% of adult cases.

Isn’t it just fun to spend time with me? Doom, gloom, and after that I’m out of relevant rhymes.

A paper published in the New England Journal of Medicine floated an unproven theory about Covid: that mask wearing may be immunizing people. The idea is that masks may cut down on the number of viruses that a person breathes in, so the body’s able to mount an immune response instead of getting overwhelmed. 

It’s the same process that made variolation–the early form of inoculation against smallpox–work. A person was deliberately exposed to a small amount of the disease and the body probably mounted an immune response. Emphasis on probably. You couldn’t be sure who would become immune and who would get sick and quite possibly die. 

The mask theory rests on two unproven assumptions: that exposure to a lower dose results in a milder case and that mild or asymptomatic cases confer some immunity. More than that, the only way to directly prove it is through clinical trials that would expose people, some wearing masks and some not, to the coronavirus. Which is unethical. So at this point it’s basically an interesting thought.
