- "I come from an area that had the most Guinea worm," South Sudan's Minister of Health, Dr. Riek Gai Kok, said at a news conference. "I never thought — even one time — that the area would be free of Guinea worm, let alone all of South Sudan would be."
"But today that dream has come true," he added.
The international effort to eradicate Guinea worm has been a huge success. Back in the mid-'80s, more than 3 million people were catching the parasite each year. Now Guinea worm is circulating in only three countries: Ethiopia, Mali and Chad. Last year, there were only 30 human cases worldwide.
