How kids learned to fake positive Covid tests–and why

TikTok videos have taught kids that they can get out of school by faking positive Covid tests. All they have to do is pour lemon juice or Coke on them. Or apple sauce, or vinegar, or hand sanitiser, or assorted other acidic liquids. Or they can rub a kiwi across them.

And here I thought TikTok was about dancing.

In Britain, at least, if they do that it means other kids in their imaginary school bubbles get sent home for ten days along with them. And their families have to stay home. But hey, if you’ve got a math test coming up–

It’s a short-term strategy, because in Britain a positive lateral flow test has to be followed up with a PCR test, which you can’t take home and use as a stir-stick for your Coke. Still, it’s a strange enough story to earn its word count here.

Irrelevant photo: Another wildflower I can’t identify. [It’s an elderflower. Thanks to DinahMow for identifying it. Somewhere in this strange thing I call my brain, I knew that.]

A spokesperson for the National Education Union suggested that Covid tests be taken in school. But that wasn’t about lemon juice and Coke. Many kids have simply stopped using the ones they’re sent home with. 

A determined spoilsport, it turns out, can override a faked positive. You can pursue that one on your own if you’re interested. The link is here.

But the story doesn’t end there. A claim’s making the rounds that lateral flow tests are useless because if you test a glass or Coke and a kiwi it will register as having Covid. And since any reasonable person knows Coke and kiwis are immune, there must be something wrong with the tests.

Shout, “Conspiracy,” here if you would.

Thank you.

A fact-checking site called, factually enough, Fact Check points to the directions from one test, which say, “This kit has been evaluated for use with human specimen material only.” This goes to the root of the problem, which is that neither the kiwi nor the Coke is human.

You can shout, “Conspiracy,” again if you want, but I won’t orchestrate it this time. I don’t think it takes a conspiracy to prove that claim. 

Alexander Edwards, associate professor in Biomedical Technology and professional spoilsport, puts it another way: “If you completely ignore the manufacturer’s instructions or in fact use the test for something completely different, then you shouldn’t really be surprised if you get a silly result.” 

 

At last: a way that Covid doesn’t spread

A study of Covid samples from hospital surfaces found that they weren’t likely to infect anyone. That lends support to the belief that contaminated surfaces aren’t a major way to spread Covid. I’d love to explain that to you in more depth but the explanation went over my head. You’ll have to follow the link and see where your head is in relation to the information.

Even without understanding the explanation, though, it reassured  me to know that the damn virus has found a way not to spread. 

 

High fashion in the Covid era

With British kids back in school (when they can’t talk their parents into parting with a lemon) and Covid restrictions easing (in spite of a more aggressive form of the virus), colds are coming back into fashion. 

I’m not basing this on personal experience. I haven’t seen anyone with a cold in a year and a half, but then I’ve never been in the front ranks of fashion. When a style starts making sense to me, that’s a signal that it’s on its way out. But I read this in multiple publications, and those of you who care about trends need to go out and get yourselves a cold. 

Parents haven’t quite caught onto this, so they’re dragging their kids into Britain’s A&E departments. (A&E stands for accident and emergency and it’s the equivalent of US emergency room.) They–that’s the panicky parents–have forgotten what it is to have a kid with a fever, a cough, and a runny nose. 

In fairness to everyone, those are also Covid symptoms and I might panic myself.

Britain’s hospitals are already overwhelmed and have been for the past year and a half. Or for the past decade or so–ever since the government started cutting funds and saying, cheerily, “We’ve never given the NHS so much money.” So they’re not in shape to add kids with minor problems to the major-problem mix. Last month, fewer than 1% of children under 15 who went to A&E needed immediate attention and more than 72% weren’t seriously ill.

And 4.36% asked their parents if they couldn’t get a Coke from the vending machine, please.

The US is also seeing a rise in the number of colds as face masks come off. 

 

A petri dish for the world

The British government’s gone sports mad lately. We’re in the midst of the Euro tournament where they play–oh, I don’t know. Some damn thing involving a ball. The game’s not the point; the crowds are, because fans travel here and there to watch the games. They eat out. They drink. For all I know, they get happy and hug.

Then they go home, and so does Covid.

In Scotland, nearly 2,000 cases have now been linked to people gathering in public fanzones, pubs, and house parties to watch the games–not to mention stadiums. Some two-thirds of those are among the 1,300 people who went to London to watch the Scottish team play there. 

For a semifinal game in Wembley, the British government plans to allow the stadium to reach 75% of its capacity–the largest crowd at a sports event in over a year. 

The World Health Organization has warned that tournament crowds (in general, not specifically this one) can act as Covid amplifiers. And the European parliament’s committee on public health warned that such a large crowd at Wembley would be “a recipe for disaster.” But Britain’s left the European Union, so we don’t have to listen to them. The reason we left the EU was so we’d be free to spread our own germs in any way we want.

If the EU passes the law of gravity, we don’t have to follow that either.

The government’s making noises about lifting most of the remaining Covid restrictions in mid-July. When it isn’t saying that we may have to take some precautions. It’s hard to know which Boris Johnson to believe, but my money’s on him lifting most restrictions. I’m basing that on how many decibels are devoted to each side.

It’s not a prospect that makes me happy. As Mark Woolhouse, a professor of infectious disease epidemiology, said, “The UK is in a unique position. We’ve the biggest Delta outbreak in a well-vaccinated country. We are a petri dish for the world.”

The question is whether vaccination breaks the link between infection on the one hand and hospitalization and death on the other. The government seems to be betting that it will. My best guess is that vaccination will weaken the link but that without other controls–masks; an effective contact tracing system; reasonable sick pay for people who are supposed to stay off work–it won’t be enough.

 

Updating the list of Covid symptoms

Assorted experts are calling for the UK to expand its list of Covid symptoms. It currently lists only the Big Three: cough, loss of the senses of smell and taste, and a high fever. 

Europe’s list includes headache, weakness, tiredness, muscle aches, runny nose, loss of appetite, and sore throat–symptoms that often begin before the Big Three and are more common in young, unvaccinated people. 

But hey, we left Europe. We get to enact our own symptoms.

 

Your small dose of hopeful news

A small study showed the Johnson & Johnson single-shot vaccine to be effective against the Delta variant.

Cold combustion as a way to kill Covid

A German project called CoClean-up (which sounds English to me, but what do I know?) has developed an air filtration system that doesn’t capture the Covid virus but destroys it, meaning that no one has to change air filters or figure out what to do with dirty filters once they’re removed.  All the process leaves behind is CO2 and hydrogen, neither of which is toxic.

The system uses cold combustion, and I never heard of it either. Air’s fed through a saline solution (basically, salt water of one sort or another). That filters out any organic particles, which includes Covid. Two electrodes run zap the saline solution. Tiny amounts of CO2 forms around one electrode and hydrogen at the other. They disperse into the room, along with the cleaned air. 

It’s still being tested, and a demonstrator model should be introduced in April. If all goes well, they expect to launch the thing commercially in another eighteen months.

A follow-up on vaccines and transmission

After falling for just long enough to tempt a person into optimism, worldwide Covid infection rates are rising again. The only exception at the moment is Africa. 

So let’s grab what good news we can: A study following vaccinated and unvaccinated health care workers reports that the Pfizer vaccine sharply reduced the number of asymptomatic Covid cases. That means that it also reduced the chances that a vaccinated person would transmit the virus: If you’re not carrying the disease, you don’t get to pass it on. Look it up in the handbook. Those are the rules. You can take it up with the management if you don’t like them.

From here on, I warn you, a lot of numbers have pushed their way in. It’s not my fault. They got in the door before I could slam it.

Ready?

In the unvaccinated group, 0.8% of the group tested positive for Covid but had no symptoms. Compare that to 0.37% in the group that had been vaccinated less than 12 days before. 

Why 12 days? That’s the number of days after vaccination when the immune system’s believed to wake up and get to work. That’s in the handbook too. It’s also the number of days in a traditional Christmas–the kind almost no one in English-speaking countries celebrates anymore. And the number of months in the calendar.

More than 12 days after vaccination, 0.2% tested positive. 

That’s not sterilizing immunity, but it does give the virus fewer chances to migrate from person to person–and with that, fewer chances to mutate. Take a deep breath. We’re making a bit of progress here. We still need masks. We still need distance. We don’t have reports on how the other vaccines are doing as far as transmission goes, and anyone who’s lucky enough to have been vaccinated needs to remember that not everyone has been and they could still pass it on. But we’re making a bit of progress.

 

Variants

A variant found in the Brazilian city of Manaus–the P.1 variant–has infected people who had recovered from an earlier strain of Covid. Out of a hundred people who recovered from an earlier strain, the estimate is that somewhere between 25 and 61 people could be reinfected. That’s a hell of a range, so we’re still dealing with rough estimates, but it’s sobering all the same, and a reminder to anyone who still believes that herd immunity will save our asses that herd immunity is not our mother and does not love us. If the big kids on the block pick on us, it will not come swooping down and send them home crying.

It’s also a reminder that until everyone is safe, no one is safe. And did I happen to mention that just ten countries have gotten three-quarters of the 191 million Covid vaccinations that have been delivered to date?)

The new variant may also weaken the effect of the vaccine being used in Brazil–one of the Chinese ones. The vaccine will still prevent severe Covid, and masks and distancing will still reduce transmission, so it’s not time to roll over and play dead, but the variant is spreading in Brazil and has popped up in other countries–24 of them at last count.

With talk of Covid variants spreading at roughly the same rate as Covid itself, the question of what to call them has gotten serious. Someone who speaks medicalese will have no problem remembering the difference between B.1.351 and VOC 202012/02, but the rest of us tend to glaze over when we hear the official names. We fall back on place names: The British variant (a.k.a the Kent variant). The South African variant. The Brazilian variant, only, oops, that’s now two variants. 

Why’s that a problem? First, because in a place as big as Brazil with as many cases as it has is almost bound to come up with more than one variant if it’s given enough time. Second, because humans are a difficult species and when a place is associated with a scary variant they tend to blame the place, along with the people who come from there. And third, because the places where the variants were found aren’t necessarily the places where the variants emerged. They just happen to be the places where they were first noticed.

So the World Health Organization has put together a committee to come up with a more sensible naming system. Not for every variant, only for the worrying ones. The names have to be easy to pronounce and easy to remember, and they have to avoid badmouthing the regions where the variants were found.  

One possibility is to name them in the order they were identified, giving us V1, V2, and so on. It’s not as much fun as naming storms, but it does avoid the problem of keeping an even balance of genders and languages.

 

Kids, Covid, Catholics, and Dolly Parton

For perfectly sensible reasons, researchers set out to discover what kids know about Covid, along with what they want to know and how they feel. They had some good questions. They knew some perfectly sensible things. We’ll ignore all of that to focus on one memorable quote.

“It is a stupid virus.”  

*

The Catholic archdiocese of New Orleans told its parishioners to avoid the Johnson & Johnson vaccine because it was developed using a “morally compromised” cell line that originated from aborted fetuses. The Moderna and Pfizer vaccines are okay, even though some lab testing involved “abortion-derived cell lines.”

What’s the difference? Beats me. 

Pope Francis has already said it’s “morally acceptable” to get any of the vaccines. So we‘ve finally found someone who really is more Catholic than the Pope.

*

Dolly Parton got vaccinated and sang–to the tune of “Jolene”–“Vaccine, vaccine, vaccine, vaccine, / I’m begging of you, please don’t hesitate. / Vaccine, vaccine, vaccine, vaccine, / because once you’re dead, then that’s a bit too late.”

To people who are hesitating, she said, “I just want to say to all of you cowards out there – don’t be such a chicken squat. Get out there and get your shot.” Click on the link and you can hear her. 

Last year, she donated $1 million to help fund research on the Moderna vaccine. 

How do we unlock a lockdown?

Britain’s poking its nose out of lockdown and looking around to see if it’s safe for the rest of the body politic to follow. A lot of people have been vaccinated–or half vaccinated, which will, we hope, hold us for the time being. The number of new Covid infections is dropping. The number of deaths is dropping. The daffodils are blooming.

Daffodils have no antiviral properties, but they do make people feel good.

So what are the prospects of getting out of this mess without setting off a new spike?

 

Daffodils. Take three and call me in the morning–or is that joke so dated that you have to be over 70 to get it?

Peeking out of lockdown

Britain’s four component nations will chart their own routes out of lockdown and each will look contemptuously at the choices the other three made, but we’ll only follow England’s here, because that’s complicated enough, thanks. 

Stage one is reopening the schools, which will open on March 8, and initially all students from secondary level on up were supposed to return at once, bright-eyed and with a negative Covid test in hand.

How were they supposed to get that negative test result? We’ll skip the details, but headteachers said there wouldn’t be time–it would take a good three weeks to get everyone tested. Teachers unions and school governors had been calling for a phased return for a good long while, although the government was ignoring them.

Hell, what do they know?

Then two days after announcing the plan, the government did a U-turn. Of course secondary schools can bring the kids back in stages. 

You’d think a government would be embarrassed to be this visibly disorganized, but if it bothers them they hide it well. And the outrage machine that makes up a large segment of the British media doesn’t seem to be bothered by it.

Once they’re back in school, older kids will take a continuing series of tests–the quick kind called lateral flow tests, which are problematic. They miss a lot of cases in the best of circumstances and miss more when done by non-experts. The kids will have a few tests at school and after that they’ll take them home to do themselves. 

These are school kids, remember. They’re the definition of non-experts. So don’t expect too much from the results here.

The government’s Scientific Pandemic Influenza Group on Modelling says the scientific consensus is that opening the schools this way will drive up the R number–the number of people that each infected person goes on to infect–by anywhere between 10% and 50%. 

Have I mentioned that teachers haven’t been a priority category in the drive to vaccinate the country? So they’re being asked to take a deep breath, walk into class, and roll the Covid dice. Masks are at least recommended for older kids in class, not just in the hallways, but that’s recommended, not required. 

Elementary school kids? Nope, they haven’t even gone that far. 

And in case the message on masks sounds too coherent, though, the school standards minister (who knew we had one?) went on TV to say that masks and testing weren’t compulsory. Parents could decide whether their kids would use either. 

I despair,” the head of one school was quoted as saying.

Let’s not go through the unlocking stage by stage. What matters is that before the country moves from one stage to the next, the situation will be evaluated. If it looks good, we move on. If not, we wait. So far so good, but what they’ll be measuring isn’t the number of cases but the number of deaths, the number of hospital admissions, the number of people vaccinated, the variant situation. So if a gazillion twelve-year-olds all test positive, it’s okay as long as deaths and hospitalizations don’t get out of control.

Are you getting a sense of why this makes my skin itch? People who test positive are the early warnings of a new spike, but the assumption seems to be that cases can be contained as long as they’re not hospitalized or dying. That kids won’t pass it to families. That teachers won’t be hospitalized and won’t pass it to partners and parents. That kids themselves won’t get seriously ill. That somehow you can get through this thing without having to worry about new cases. That as long as the hospitals aren’t overwhelmed and people aren’t dying in the streets, it’s okay. 

What the government’s doing is betting heavily here on vaccines and tests, hoping to keep the number of cases down to a manageable level until those save our hash. And it may work. In the meantime, forgive me if I scratch where it itches. I like our hash. I don’t want to see us lose it.

The Royal College of Paediatrics and Child Health says that vaccinating children and teenagers could be the way out of this mess,  but the vaccine trials involving kids have only just begun. We should hear the results in six months or so. That’s not a quick hash-saver.

Another detail that makes me itch as we poke our collective nose into the open air is that healthcare workers still don’t have proper protective equipment. Twenty healthcare bodies have written  to the prime minister about this. In response, the prime minister rumpled his hair and asked if he didn’t look cute. 

Okay, what the government actually said was that it was monitoring the evidence and would update advice “where necessary.” And by the way, didn’t the prime minister look cute?

Healthcare workers are four times more likely to become infected than the rest of us, and within hospitals people working in intensive care have gotten the highest grade protective equipment, but it turns out that people working on the general wards have double their rate of infection–and less effective protective gear.

But, what the hell, the country’s only had a year to get this right. And we do have a prime minister who knows how to rumple his hair.

Meanwhile, the government is paying consultants to locate the protective equipment that it owns and that it stored someplace, although no one person knows exactly where. Billions of pounds worth of the stuff is stashed here and there.

“We have amounts in containers, in storage around the country; there are some on the docks and there are some en route from China,” the auditor general said. 

I wonder if that’s what’s on the floor by my computer. If so, I’d really like it out of there when the prime minister’s done with his hair. It was only supposed to be there for a couple of days. 

Some of the equipment will go out of date if it’s not used. Some of it is needed in hospitals and (yup, see above) isn’t available. Some of it–possibly all of it–was bought by external consultants at inflated prices and I should have known better than to let them store it on my floor but they were being so damn nice

Anyway, they don’t seem to have a central system to track all this, so they’re paying consultants to figure out what they own and where they can find it. 

You’d laugh if it weren’t so expensive. 

 

The sciency stuff

Lab studies have confirmed that the mutation common to the British, South African, and Brazillian variants really does make Covid more contagious than the original form. The initial argument was based on modeling, and I was holding out for confirmation, thinking that maybe the variants had just gotten lucky. Now, damn them, the scientists have given me what I asked for. So yup, it’s more contagious.

New York and California–not to be left out–have developed (or found, since we don’t really know where any of the variants first emerged) variants of their own. Let’s not panic about them until more is known. There’s always time for that later.

*

A new quick Covid test has been developed in France. It gives you a result in ten minutes–a third the time of the lateral flow tests–and it’s more accurate, although still not perfect. It’s 90% accurate, with the remaining 10% taking the form of both false negatives and false positives.

That’s good news, but it’s going into a three-month trial, so don’t rush out and try to buy a few thousand of them for your local school. 

*

The US Food and Drug Administration has said that Johnson & Johnson’s one-dose vaccine is both safe and effective. That’s not yet approval, but it’s a move in the right direction. If you don’t read past the headlines, you may not fall in love with it: It’s only 66% effective, which is lower than the be-sequined two-dose vaccines that crossed the finish line first and got all the cheering.

Read past the headlines, though.

The vaccine was tested in the US, several Latin American countries (sorry–I don’t know which ones), and South Africa, and 66% is the number that comes out of the jar once you pour all those results together and shake them. In the US, it was “much closer” to the be-sequined numbers. The effectiveness depended on which variants were prevalent in which countries. 

How much closer is “much closer”? In the US, it’s 72% effective. In South Africa, 57%. After that, I run out of numbers. Sorry. 

That’s still not in the 90% zones of the star vaccines, but all the vaccines (“all” here means the ones that have been approved in the US, but may well include others that are in use around the world) are 100% effective at preventing hospitalization and death. That’s no small thing. 

 

Creativity and lockdown
In a recent blog post, Emma Cownie asked, Can the boredom of lockdown push us to be more creative? For her, the answer has been yes, and it’s also worked that way for Peter Quinn, who creates special effects for a living. You know special effects–those things we see in movies that kids think are real and adults–um, yeah, we sometimes think they are as well. I won’t try to describe what he’s done, but he’s created a few sequences just to make himself laugh, and he’s strung them together in a video clip. 

They made me laugh too. Go on. Watch it. It’s good for your immune system.
