Delighted to have had this wide-ranging conversation with @pathogenscribe.bsky.social covering biological weapons, accidental release, the importance of precision in terminology, mitigating airborne pathogens, dual use research of concern, and much more. Thanks for having me on, Heather!

The 1968 flu pandemic occurred between 1968 and 1970 and killed up to 4 million people globally.
It is among the deadliest pandemics in history. Apparently, we didn't learn much because viral pandemics keep happening again and again and again...

Healthcare workers need to realize that the profession demanding you "push through" everything increasingly sees you as an assembly line worker, only there to mindlessly follow guidance from medicine's management class - and if #longCOVID stops you from doing that, you will be discarded too.
Healthcare Workers With Long COVID Struggle to Find Support
Some healthcare workers fail to recognize the symptoms of long COVID in themselves, says one physician.

Essential reading for everyone in the medical profession, regarding #longCOVID and the need to listen to patients. This one, by an MD, is going to get printed out and brought to a lot of appointments.

Also worth reflecting on the role of humility in "building the plane while we flew it".

Long-term cardiac effects of COVID-19 in children: ➡️ In a prospective case–control study, children with prior SARS-CoV-2 infection showed a persistent reduction in left ventricular global longitudinal strain (GLS) up to 1 year post-infection. ➡️ Key insight: Despite normal conventional echocardiographic parameters, GLS was significantly reduced — indicating subclinical myocardial dysfunction that would otherwise be missed on routine echo. 1/

adam.tsuris @AdamTsuris Somewhere along the way, being wrong about facts was reclassified as "having an opinion," and knowing facts was stigmatized as "having bias." It's a big part of why we're in hell now.
