90 THIRD WHO REPORT ON NEGLECTED TROPICAL DISEASES
***
Burden and distribution
During the 1980s, dracunculiasis was endemic in 20 countries in WHO’s African, Eastern
Mediterranean and South-East Asia regions. In 1989, a total of 892 055 cases in 13 682 villages
were reported from the 15 countries that submitted reports from village-based case searches
(2). In 2013, a total of 148 cases were reported from 103 villages: 113 cases in 79 villages
(South Sudan); 14 cases in 10 villages (Chad); 11 cases in 8 villages (Mali); 7 cases in 5 villages
(Ethiopia); and 3 cases in 1 village (Sudan) in areas bordering South Sudan (1). From January
to August 2014, a total of 82 cases were reported from 50 villages: 70 cases in 38 villages (South
Sudan); 9 cases in 9 villages (Chad); 1 case in 1 village (Mali); and 2 cases in 2 villages (Ethiopia)
(1) (Fig. 4.4.1).
Fig. 4.4.2 shows the steady decline in the number of cases reported monthly. The overall
increase observed during July–August 2014 resulted from the recorded increase in the number
of cases reported in South Sudan during those months compared with the same period in 2013.
