Welcome to Scientific Americans Science Talk posted on August 31st, 2015. I'm Steve Murski.

This past week, Scientific Americans celebrated the 170th anniversary of our first issue,

so we had a little party. More on that in about eight minutes first,

Jimmy Carter has been in the news of late due to his announcement that he's fighting metastatic cancer.

Back in January, the former president and 2002 Nobel Peace Laureate spoke to Scientific American Editor-in-Chief Marietti Christina at the American Museum of Natural History in New York City.

Thank you very much, President Carter, for being with us today.

And the first thing is today, you've just made some announcements about the Carter-Sutgers work in Guinea Worm

and the progress since you began working on that in 1986.

Can you speak to that for just a minute, how that's going and what remains to be done?

Well, we began the eradication of Gini Worme from the face of the earth in 1986.

We found the disease in 20 countries, three in Asia and the rest of them in Sub-Sahara Africa.

When we began to complete our survey, we had been in 23,500 villages and we found 3.5 million cases of guinea worm then.

Last year we had 126 cases, so now we know every person on earth that has guinea worm and we're monitoring very closely And we expect Gany Worm to be the second disease in the history of the world to be completely eradicated from the face of the Earth.

So we're very pleased with what's going on and it's still got a bigger challenge because those last 126 cases,

some reason they haven't been eradicated yet so they are quite intransigent and

cost a lot of money and effort to get those last cases done so guinea worm is a horrible
