For surveillance purposes, village-based health workers search for infected persons in each village with endemic disease and complete a register that provides the basis for monthly zonal, district, and national surveillance reports.5 During 1999, dracunculiasis was endemic in 13 countries in Africa.† These countries reported 96,293 cases in 10,914 villages. Of the total number of cases, Sudan reported 66,097 (69%) cases in 7271 villages; 2606 of the known villages with endemic disease in Sudan were not accessible to program surveillance. Outside Sudan, 93% of 3068 villages reported monthly; in Sudan, 44% of 4892 accessible villages reported monthly. Outside Sudan, 20% of all villages with endemic disease reported 1 case each. Seven of the 13 countries with endemic disease reported less than 500 cases each in 1999.
