1/ Just because you have a PhD in health or science doesn’t mean you know shit about health or science. 🧵

📌 Fair warning, Sean: I'm gonna use this thread to dramatically expand my #HalloweenTombstones this year (see my pinned thread) Won't be the first time I've shared your resources and made myself look smart in the process.

2/ If you study people’s shit, but don’t know it’s used to detect viral shedding trends in a community—you’ve already lost the plot.

3/ If you think “mild” means “safe,” you don’t understand immunology. Every infection = immune injury. Repeated infections = compounding damage.

4/ If you shrug at airborne spread but teach “disease prevention,” you’ve confused education with indoctrination.

5/ If you talk about “personal choice” but ignore community transmission, you’ve abandoned public health for politics.

Landowners should be free to set whatever requirements they want on their own land. But trying to force people who disagree with you to act a particular way through the force of law will inspire rebellion.

6/ If you think disability stats are “overestimates,” you’re telling on yourself: you don’t know how to read a denominator.

7/ If you push “herd immunity” through infection, you’ve missed the first principle of epidemiology: prevention always costs less than repair.

8/ If you claim COVID is like the flu, yet can’t explain endothelial dysfunction or microclots, you’ve confused vibes with science.

9/ If you don’t understand long-term sequelae but insist the pandemic is “over”—congrats, you’re doing PR for the virus.

10/ Science isn’t about titles. It’s about evidence. And the evidence is clear: COVID isn’t done with us—just because you’re done with COVID.

11/ If you think “endemic” = “harmless,” you don’t know history. Malaria is endemic. Tuberculosis is endemic. Both still kill millions.

"Personal risk assessment" is bullshit conservative speak for "only care about yourself." Unfortunately, a majority of Democrats have embraced this ideology as well. 90% or more don't bother wearing a mask to the grocery store or other crowded indoor places all -- or even most -- of the time.

At the rate we're going, the vulnerable will never be able to "get back to normal." US society at large doesn't give a shit. SO please....keep on living life while totally disregarding the effects apathy and selfishness have on those at risk -- which also includes the healthy.

There is something called the precautionary principle. We know MANY viruses that harm the immune system, so we cannot assume sars2/c0v1d is mild. Even flu is harmful. Also, we have seen harmful viruses harm the brain (from flu, for instance) We have seen ignorance on measles from doctors.

Ditto if you DON'T have health or science degrees. Irish Health Minister during Covid-19, Simon Harris, dropped out of university. Thought Covid-18 was before Covid-19.🙄 #irishpol

Brief and thorough. Might I add: If your patients have read more SARS-CoV-2 lit than you have, you shouldn't be a doctor.

Great thread & solidarity from across campus. As the lone masker in my office and probably building, one of the many ?s running through my mind is "aren't they concerned about protecting their brains...?" 🤷‍♀️
