This is obviously a worrying development, especially considering the fact that air travel was involved. I am considerably more concerned by the ongoing outbreak of Ebola in this region than I am by current events in Russia. www.bbc.co.uk/news/article...

Many people have recently reached out to me regarding the current situation in Irkutsk. Right now, the information environment there is both too sparse and too unreliable to base any firm analysis and / or prediction on. The next week will make the picture much clearer.

A friend has Covid right now. They have lost their sense of smell and they're having cognitive problems. This hit me today, as it often does: we made, and continue to make, a huge collective mistake in allowing a virus that impacts the brain to transmit unmitigated globally.

I am rarely affected by discourse on social media, but the current wave of posts asserting that Long Covid is psychosomatic has angered me. To be very clear: if you're asserting that LC isn't a physical disease, you're ignorant of science. End of.

The disconnect between the millions of dollars being thrown at biosecurity / biodefense right now and the simultaneous mocking of people wearing masks is so painfully, tragically stark. A respirator is a tool, just like a biosensor or a biological countermeasure.

A contractor was at my house a few days ago. The last time he was there - about two years ago - he told me that he'd been having some brain fog after Covid. This time, he told me, completely nonchalantly, that he, 'can't remember anything now'. He's ten years younger than me.

Articles like these are emblematic of the institutional amnesia surrounding Covid-19. A pathogen that emerged less than seven years ago, which can cause fatigue during the acute infection and as a common long-term effect, not even mentioned. Conspicuously absent. www.nbcnews.com/health/menta...

8. The vision I have of a world where infectious diseases are things of the past, no longer threats, started in the simplest of ways: a son, in 2020, wanting to visit his desperately frail mum. Who I now miss desperately. /end

7. This is why I work with and connect companies, organisations, and people that are all working to solve parts of this problem: biosurveillance, biodetection, infection control and mitigation, screening and diagnostics, and therapeutics. It is now my life's work.

6. No-one should have to go through what I did, engaged in a constant calculus of avoiding infection so I could visit my dying mother right up until the end.

5. No-one should have to go through what my mother did, isolated for long periods at the start of the pandemic when visiting was banned during outbreaks of the virus.

4. Because I didn't want to get infected and be unable to visit my mother, who could have passed away at any time from mid-2021. Three years have passed now, and my mother - my indomitable mother - would want me to express the following to you all:

Conor Browne @brownecfm.bsky.social · 17/09/2026
3. Because I didn't want to be responsible for bringing the virus into a nursing home, where every resident was, by definition, clinically extremely vulnerable. Because I didn't want to inadvertently infect my mother.

2. I visited my mother almost every day, testing for SARS-CoV-2 infection every single time. Wearing a respirator, every single time. Why?

1. My mother passed away three years ago today. She died in the early hours of the morning in the nursing home she had lived in from late 2019. The nursing home was, at that point, in a Covid-19 outbreak, the eleventh outbreak in the facility since the pandemic began.

The disconnect between the frenetic discourse regarding the potential risk of AIxBio enabled biological weapons being developed and the political reality in the US, where antivaxx ideology is being institutionalised and masking near-demonised is stark.

Conor Browne @brownecfm.bsky.social · 10/09/2026
2. While the potential for AIxBio weapons are a risk we must contend with, and mitigate to the greatest extent possible, we must not become so focussed on this potential risk that we forget or somehow diminish the risk that *already exists*. /end

Conor Browne @brownecfm.bsky.social · 10/09/2026
1. I am concerned by the very real threat of AI-enabled biological weapons, but also by the current hyper-fixation on their potential development and use. It is vital to remember that highly effective biological weapons could be developed right now with absolutely no AI involved.

The strange dissonance of sitting in the main entrance foyer of a major hospital in Northern Ireland, with SARS-CoV-2 prevalence increasing here to boot, and seeing hundreds of people walk past, all unmasked, and realising that some of those people are going to get Long Covid.

'Our findings suggest that SARS-CoV-2 infection can activate an immune program that closely resembles those involved in established autoimmune disorders...'. I have seen this so many times now. New-onset autoimmune disease following COVID-19.

I agree - the problem is that in the UK, the JCVI (Joint Committee on Vaccination and Immunisation) makes that decision. Their decision making process is based on a very flawed calculation of cost-benefit, and lobbying for change is extraordinarily difficult.

'Vaccination against COVID appeared to have a dose-response protective effect. The more doses workers received before infection, the less likely they were to report prolonged symptoms'. This dose-response effect is why I get vaccinated every six months.

I dislike sharing anecdotes, but I genuinely feel compelled to inform you all that in the past week I have found out that two more people I know have Long Covid, and that a family friend is still shielding. As you all know already, 'normality' is fundamentally a veneer.

3. ... protect my sobriety. This is why I accept the small risk of outdoor infection through outdoor socialising; because *for me* it mitigates the ongoing and larger risk to me of drinking alcohol. Risk is often complex, multi-faceted, and personal. /end

2. ... to me than my sobriety. Nothing. I would sooner deliberately be infected with SARS-CoV-2 than drink a single alcoholic drink. Way back in 2020, I determined that maintaining an outdoor social life - predominantly having coffee with friends in outdoor settings - was a necessity in order to...

1. These are good points, and deserve an honest and transparent answer. The reason I stressed 'for me' is because SARS-CoV-2 infection is *not* the primary risk I face on a day-to-day basis; the primary risk I face is drinking alcohol. I am now over 19 years sober and nothing is more important...

Conor Browne @brownecfm.bsky.social · 24/08/2026
I absolutely take your point, but - for me - and really stressing, 'for me' here - I realised a long time ago that my masking had to be sustainable over the long term. Not masking outdoors gives me the fortitude to continue masking indoors, forever if necessary.

As I'm sure you know by this point, Covid-19 continues to concern me (which is why I take serious measures to avoid infection, including masking in all public indoor spaces). However, no virus concerns me more than H5N1. We are giving this beast too much room. theconversation.com/first-bird-f...

2. Ergo, rather than dismissing SARS-CoV-2 as something along the lines of 'just another respiratory virus' you should realise than unprecedented pathogens could cause unprecedented long-term health impacts beyond the acute infection. And protect yourself accordingly. /end

1. A reminder that if you do believe that the Covid-19 pandemic occurred as a result of accidental release from a laboratory, then you're also tacitly acknowledging that said pandemic is an unprecedented event caused by an unprecedented pathogen.

Walking The Boyne Camino in the Republic of Ireland from Drogheda to Mellifont Abbey a couple of days ago.
A photograph of a forest path. The path

stretches from the left foreground of the photograph to the midground, where it turns to the left and out of the frame. The path is crossed by dappled light and edged by fallen leaves. The upper half of the photograph is dominated by the green of trees and the blue of wildflowers. In the right midground of the photograph is a gnarled tree trunk, reminiscent more of a sculpture than a tree, with a yellow arrow painted on it.
