This discussion follows “How Guinea worm disease went from 3 million cases to 126,” an in-depth look at a treacherous virus in Africa that’s close to becoming fully eliminated.

In the late 1980s, Guinea worm disease — a nasty, parasitic infection caused from drinking contaminated water — affected more than 3 million people in Africa. Now, only an estimated 126 cases remain.

In a Google Hangout on March 3, we’ll be joined by Dr. Donald Hopkins, vice president of health programs at the Carter Center, and Dr. Mark Siddall, curator for the division of invertebrate zoology at the American Museum of Natural History.

We’ll talk about how Guinea worm disease spreads, its symptoms and the process by which it’s being wiped out.

Join our Hangout, above, on Tuesday starting at 12:45 p.m. ET. Do you have any questions you’d like answered? Share them in the comments and we’ll try to include them.

For background on the disease, watch our interview with former U.S. President Jimmy Carter about one of his early memories witnessing the virus in action:
