Provisional data show a total of 1,129 cases reported from the four remaining endemic countries (Sudan, Ethiopia, Ghana, Mali) in January-July 2010, which is 43% fewer cases than the 1,994 cases that were reported during the same period of 2009. 75% of this year’s cases have been contained so far, versus 78% of cases in January-July 2009. Figure 1 and Table 1 indicate the number of cases reported by country during January- July 2010. Sudan accounts for 98% of this year’s reported cases, whereas Ghana, Mali and Ethiopia combined account for only 28 cases, a reduction of 90% from the 289 cases they reported during the same period in 2009 (Figure 2).
