As I've said before, the distinction drawn between acute infectious diseases and chronic diseases is, in many cases, artificial. This is the huge flaw in MAHA: infections can and often do cause chronic disease; vaccines can thus prevent some chronic diseases.

Why acute infections can lead to neurodegeneration
Researchers are uncovering the mysteries of why early-in-life acute infections can lead to neurodegenerative diseases in later years.

International Men's Day. Guys, check in on your friends; if you need help, ask, and, importantly, remember the version of masculinity you're being sold online and by many politicians isn't masculinity, it's cruelty. Last, there's nothing unmasculine about protecting your health.

Everything about SARS-CoV-2 weakens us as a species. Population-level immune dysregulation leading to both reactivation of latent pathogens and creating niches for new ones; the politicisation of our response regressing public health and massively amplifying anti-vax ideology.

Increasing prevalence of H5N1 globally, drastically reduced surveillance in the US, H3N2 driving a severe flu season in the Northern Hemisphere, a mismatched flu vaccine, and the possibility of undetected human - human transmission of H5N1 is a recipe for a reassortment event.

In the light of this, it's important to establish the relationship between reactivation of EBV (which, of course, can be triggered by SARS-CoV-2 infection) and the development of new-onset lupus.

Masking indoors in public spaces boils down to this for me now:

I love never being sick from airborne infectious diseases.

The last cold I had was in early 2019, with not even a sniffle since. The only thing I don't do is dine indoors in public spaces; a good trade for health.

H5N1 infections in wildfowl and poultry are increasing quickly in North America and Europe as a result of the southward migration of wild birds. With a severe flu season ahead of us, driven by H3N2, the risk of reassortment has significantly increased.

The reason for this is multi-factorial, but the fact that Long Covid is not mentioned once is extremely telling. Especially since the article makes an explicit comparison with 2019.

Considering the vast amount of evidence that Covid can cause serious long-term health problems, mitigating risk of infection is absolutely logical. This should be utterly uncontroversial. But alas, politics, tribalism, and a desire to conform trump logic for most people. Not me.

1. My background is in CBRN defense. I was involved in the field long before the emergence of SARS-CoV-2.

I used to essentially discount comments on social media - especially this platform - as fringe, not representative of the real world. Sadly, this is no longer the case.
November 2, 2025 at 10:28 AM
1. Fundamentally, a significant part of what I do is the prediction of both the behaviour of pathogens in the future and our likely collective response to future pathogenic threats. I have an excellent track record in this regard for two main reasons:
November 1, 2025 at 10:37 AM
1. The possibility of low-level human to human transmission of H5N1 occurring under the radar is something that has concerned me for several months now.

1. I read a study that hinted at this over a year ago. Although the overall individual risk seems to be small, there will be impacts at the population level. The effects of pathogens are an inconvenient truth for MAHA.

I believe that the state and media backed changing of the meaning of the word, 'Covid' to 'the period of time when non-pharmaceutical interventions were in place' rather than the disease itself will, in the future, be seen as the most damaging linguistic trick in history.

I try to be professional on this platform but there are times, like now, when it hits me hard on a visceral level that we are in the midst of a catastrophic global public health crisis and it seems, as a species, we've somehow decided that ignoring it is the best plan we've got.
October 28, 2025 at 12:42 AM
1. Please read the article (linked in the next post). What galls me is that there is nothing 'astonishing' about this; it was absolutely predictable. The reasons are multi-factorial, but low uptake of flu and Covid vaccines (and very tight eligibility for the latter) are a large part of the problem.
October 26, 2025 at 9:21 AM
The pandemic has, and continues to have, significant effects on global politics. I am certain that in the future entire books will be written on this subject, but these effects can be distilled to one concept: the vast majority of people have normalised that which is abnormal.

Every time I hear someone who was in government in the UK in 2020 mention lockdown, I immediately remember walking through the streets of Belfast during the Eat Out to Help Out scheme, seeing throngs of people packed in restaurants, and thinking this will kill so many.
October 23, 2025 at 10:11 AM
I don't know what pathogen will cause the next pandemic - Disease X - but what I do know is that the combination of the immune dysregulation effect of SARS-CoV-2 and the political legacy of our response to Covid means this pandemic makes us much more vulnerable to the next one.

1. There has obviously been considerable discussion regarding the differences and similarities between HIV / AIDS and SARS-CoV-2 / Covid-19 on this platform over the past few days.
