Nigeria Eliminates Guinea Worm Alanna Shaikh, MPH December 8, 2009 The New York Times reported yesterday that Nigeria has eliminated Guinea worm. It’s been an entire year since a worm was seen. This is a big deal. Guinea worm is a horrifying monster of a parasite; the worms can grow to three feet long and come busting out of human skin through an open sore. There is no medication for someone infected with a guinea worm.
