I met up with an old friend for a walk earlier this week, taking advantage of a glorious sunny autumn day.
He's not covid cautious or conscious and he didn't know I am, so when I put on a mask to go inside a public building he was taken aback.
"Do you always do that?"
Yes I do.
We continued on our walk, chatting about all sorts of other stuff, and he brought the subject back round to the mask.
He respects me, and I respect him, so respectfully he asked if I thought masks worked.
I said that it depends what you mean by 'work'.
They reduce the amount of airborne particulates you inhale.
Covid is spread mostly by people exhaling and inhaling airborne particulates.
So if you want to reduce your risk of catching Covid by reducing the amount of Covid you inhale, then yes they work.
They're not perfect, but what is?
I've been watching all my colleagues get repeatedly sick, while I've stayed well for five years.
And then he asked what made me think that covid was worth avoiding.
I thought about my reply for a moment, and then said "science"
Not anxiety, or fear, or superstition.
Science.
The science outlining what Covid infections are doing is solid and vast.
And the links between what science predicts (eg that covid infections will cause disability) and the effects we see in the everyday (rising disability) are unequivocal.
I've given up trying to always be a cheerleader in these kind of situations.
It's a path that most people are unwilling to consider, so people can take or leave my opinion.
But he asked, so I told him.
I told him that I think everyone ages but people who catch Covid repeatedly age quicker in terms of key indicators like lung and brain and heart health.
I told him that waves of Covid infection cause ambulance delays and hospital overcrowding.
I told him that sickness rates in some sectors have doubled.
I could have kept going, but I didn't have the energy or the heart.
He acknowledged that it was potentially true.
But he, like so many others, thinks that he couldn't handle the lifestyle change.
And since we were being honest, I said that isn't a luxury that people with Long Covid have.
They don't get to choose their lifestyle change.
They have had it forced on them by a society that has chosen to get sick and make them sick.
At which point, to my astonishment, he told me that his wife has long covid.
I boggled for a while.
I'm still boggling now.
My mind is boggled.
I told him that the biggest risk factor for worsened long covid seems to be repeat infections.
And we talked about some other stuff like kids and jobs and friends we know whose health has mysteriously gone downhill in the last two years.
But all of the rest of the stuff hung in the air.
I don't know what he's going to do with it.
When a culture is so set against recognising a danger, it's very hard for an individual person to turn and go against that flow.
Good luck to all of the people who hear and make that turn.
Oh, just going to clarify this.
He actually said "My wife thinks she has Long Covid".
Sitting chatting to a friend who turned and casually announced, "oh, no, I'm a bit tired after my TIA"... and I mentally added it to my enormous list of people I know who have had TIAs recently.
A quick thread on TIAs... Covid... and Heatwaves...
... and how the covid and heatwaves can combine in effect, basically by pushing the circulation towards lower blood flow, thicker blood and easier clotting.
During hot weather, you sweat.
If you do not replace enough fluid, the volume of liquid circulating in your bloodstream falls.
There is simply less blood available to move around the body.
Today was the last day of term at one of our local schools, and after I did the end of term assembly, one of the teachers asked if I could stick around and meet a class to answer some questions.
I had an hour free, so I did.
It was an 'A level' biology class. A levels are the exams you take at about age 18 here in the UK. You normally take about 3 or 4, so students often specialise in subjects that will lean towards what they will go on to study at university.
The teacher knows me well, and he knew that some of his class were interested in the intersection of faith and science - including pupils from Hindu, Muslim and Christian backgrounds - so he wanted to give them an opportunity to ask some questions.
It's now a very widely established scientific fact that covid infections are not all cleared within weeks of infection.
It's not clear what proportion of people undergo persistent infection, but it's not a trivial number, or a rare occurrence.
We have multiple independent lines of evidence for this, including biopsies, autopsies, viral RNA and proteins found months later, successful virus culture in some cases, and sequencing showing the virus continuing to evolve within the same person over time.
No single study proves it on its own, but together they build a remarkably consistent picture that persistent infection is a genuine feature of SARS-CoV-2.
I've been writing a really long thread on the long covid dopamine study, but it's incredibly long winded and complicated and boring and depressing, and even I'm fed up of it, so here's the five tweet version:
I park my vintage 1970s steel car in the sea for a year, then take it out and wonder why it doesn't work.
I ask a mechanic whether the starter motor is rusty.
He says yes the starter motor is rusty.
Is there anyone in their right mind who would think that the starter motor is the only thing that is rusty?
🚨OH MY WORD. I WARNED FOUR YEARS AGO THAT REPEAT COVID INFECTIONS IN KIDS MIGHT LEAD TO EXACTLY THIS CONDITION.
I said that with Covid affecting blood vessels, immune signalling, inflammation, gut, nutrient absorption, nutrient handling, and calcium recycling processes, we should expect a wave of molar incisor hypomineralisation.
I was very surprised that the problem hadn't made it into the media before now - but I guess the children this is happening to now are the children who were born in 2020. The ones who were infected every year since.
There are some people who would have you believe that vaccines basically all work the same for different infections, and all have the same effect, but that's not true.
Let me explain this as simply as I can:
Some vaccines are like *insurance*.
You are unlikely to get tetanus, but if you do, vaccination can turn a catastrophic outcome into something far less dangerous. It is protection against a *rare but awful event*.
Some vaccines are like a *firebreak*.
The measles vaccine doesn't just protect the person receiving it. When enough people are vaccinated, measles struggles to find new people to infect, so the whole community is protected, including babies and people who cannot be vaccinated.
