Beating the asymptote: The end of rinderpest
October 22, 2010 2 Comments
Goodbye, Rinderpest. Hello, Healthy Cattle.
The news is the effective eradication of rinderpest, a viral disease of cattle. Rinderpest does not infect humans, and even in animals it barely occurs in the Americas (or Australia or New Zealand), though until recently it was common and devastating in Africa, South Asia and the Middle East. So unless you are a large-animal veterinarian or a cattle farmer, the disease might never have been on your radar.
So why care that it is on the verge of being removed from the world? Because this marks the first time that a disease of animals has ever been eradicated — and only the second time that any disease has been eradicated at all. The first was smallpox. That was 30 years ago.
Since then, seven other human diseases have been targeted for eradication: Guinea worm (dranunculiasis), elephantiasis (lymphatic filariasis), measles, mumps, rubella, cysticercosis, and above all polio. None of those eradication programs have yet reached their target. Polio has probably come closest, at the cost of billions of dollars and undoubted millions of hours of volunteer effort — yet each time the goal seems within reach, the disease roars back again.


Actually, from the research I’ve followed, it appears that there is something that can cause it to enter some sort of stasis period whereby it can be flushed from the system over a short period. Which is how some babies born with it can actually become AIDS free. Something about the rapid turn over rate of cells within a growing baby. I look forward to seeing more research along those lines in the future.
That is wonderful, that they are learning to eradicate disease. Let’s hope they get much further with their research!
Interesting, what Kzinti said, about the AIDs babies.
