Guess who's blogging now? We interrupted a class of children, six to eight years old, to ask them a few questions. All of them raised their hands eagerly when asked how many had had Guinea worms and indicated the scars on their little bodies. The smallest child, named Shadrach, reminded me of our grandson Hugo, who always has clean water to drink and will never be afflicted with three-foot-long worms developing in his body and then penetrating his skin to emerge over a period of several weeks through a painful sore that may cripple him for life. At least Shadrach and his friends now know that the use of a filter cloth can protect them completely, and we're determined to eliminate the worms permanently.
