Humans have only eradicated 3, maybe 4 diseases. Smallpox was the first
Rinderpest was second.
We got a whole strain of flu, pretty much by accident, during lockdown/masking.
We're still waiting for the final final death call on guinea worm disease, thank you Jimmy Carter et al.
Screwworm eradication was a parasitology moonshot. It was huge, ambitious, expensive, and required extraordinary international cooperation. It is one of the greatest technological marvels nobody’s heard of outside livestock circles and a select group of weirdos, of which I’m one.
